# astro

## 5.18.0

### Minor Changes

- [#15589](https://github.com/withastro/astro/pull/15589) [`b7dd447`](https://github.com/withastro/astro/commit/b7dd447e319a7b435c01ccd69347e5261bd9dc14) Thanks [@qzio](https://github.com/qzio)! - Adds a new `security.actionBodySizeLimit` option to configure the maximum size of Astro Actions request bodies.

  This lets you increase the default 1 MB limit when your actions need to accept larger payloads. For example, actions that handle file uploads or large JSON payloads can now opt in to a higher limit.

  If you do not set this option, Astro continues to enforce the 1 MB default to help prevent abuse.

  ```js
  // astro.config.mjs
  export default defineConfig({
    security: {
      actionBodySizeLimit: 10 * 1024 * 1024, // set to 10 MB
    },
  });
  ```

### Patch Changes

The protocol check no longer fails due to hostname mismatch against the hardcoded test URL.

## 5.17.3

### Patch Changes

- [#15564](https://github.com/withastro/astro/pull/15564) [`522f880`](https://github.com/withastro/astro/commit/522f880b07a4ea7d69a19b5507fb53a5ed6c87f8) Thanks [@matthewp](https://github.com/matthewp)! - Add a default body size limit for server actions to prevent oversized requests from exhausting memory.

- [#15569](https://github.com/withastro/astro/pull/15569) [`e01e98b`](https://github.com/withastro/astro/commit/e01e98b063e90d274c42130ec2a60cc0966622c9) Thanks [@matthewp](https://github.com/matthewp)! - Respect image allowlists when inferring remote image sizes and reject remote redirects.

## 5.17.2

### Patch Changes

- [`c13b536`](https://github.com/withastro/astro/commit/c13b536197a70d8d4fd0037c5bd3aaa2be0598b9) Thanks [@matthewp](https://github.com/matthewp)! - Improves Host header handling for SSR deployments behind proxies

## 5.17.1

### Patch Changes

- [#15334](https://github.com/withastro/astro/pull/15334) [`d715f1f`](https://github.com/withastro/astro/commit/d715f1f88777a4ce0fb61c8043cccfbac2486ab4) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - **BREAKING CHANGE to the experimental Fonts API only**

  Removes the `getFontBuffer()` helper function exported from `astro:assets` when using the experimental Fonts API

  This experimental feature introduced in v15.6.13 ended up causing significant memory usage during build. This feature has been removed and will be reintroduced after further exploration and testing.

  If you were relying on this function, you can replicate the previous behavior manually:
  - On prerendered routes, read the file using `node:fs`
  - On server rendered routes, fetch files using URLs from `fontData` and `context.url`

## 5.17.0

### Minor Changes

- [#14932](https://github.com/withastro/astro/pull/14932) [`b19d816`](https://github.com/withastro/astro/commit/b19d816c914022c4e618d6012e09aed82be34213) Thanks [@patrickarlt](https://github.com/patrickarlt)! - Adds support for returning a Promise from the `parser()` option of the `file()` loader

  This enables you to run asynchronous code such as fetching remote data or using async parsers when loading files with the Content Layer API.

  For example:

  ```js
  import { defineCollection } from 'astro:content';
  import { file } from 'astro/loaders';

  const blog = defineCollection({
    loader: file('src/data/blog.json', {
      parser: async (text) => {
        const data = JSON.parse(text);

        // Perform async operations like fetching additional data
        const enrichedData = await fetch(`https://api.example.com/enrich`, {
          method: 'POST',
          body: JSON.stringify(data),
        }).then((res) => res.json());

        return enrichedData;
      },
    }),
  });

  export const collections = { blog };
  ```

  See [the `parser()` reference documentation](https://docs.astro.build/en/reference/content-loader-reference/#parser) for more information.

- [#15171](https://github.com/withastro/astro/pull/15171) [`f220726`](https://github.com/withastro/astro/commit/f22072607c79f5ba3459ba7522cfdf2581f1869b) Thanks [@mark-ignacio](https://github.com/mark-ignacio)! - Adds a new, optional `kernel` configuration option to select a resize algorithm in the Sharp image service

  By default, Sharp resizes images with the `lanczos3` kernel. This new config option allows you to set the default resizing algorithm to any resizing option supported by [Sharp](https://sharp.pixelplumbing.com/api-resize/#resize) (e.g. `linear`, `mks2021`).

  Kernel selection can produce quite noticeable differences depending on various characteristics of the source image - especially drawn art - so changing the kernel gives you more control over the appearance of images on your site:

  ```js
  export default defineConfig({
    image: {
      service: {
        entrypoint: 'astro/assets/services/sharp',
        config: {
          kernel: "mks2021"
        }
    }
  })
  ```

  This selection will apply to all images on your site, and is not yet configurable on a per-image basis. For more information, see [Sharps documentation on resizing images](https://sharp.pixelplumbing.com/api-resize/#resize).

- [#15063](https://github.com/withastro/astro/pull/15063) [`08e0fd7`](https://github.com/withastro/astro/commit/08e0fd723742dda4126665f5e32f4065899af83e) Thanks [@jmortlock](https://github.com/jmortlock)! - Adds a new `partitioned` option when setting a cookie to allow creating partitioned cookies.

  [Partitioned cookies](https://developer.mozilla.org/en-US/docs/Web/Privacy/Guides/Privacy_sandbox/Partitioned_cookies) can only be read within the context of the top-level site on which they were set. This allows cross-site tracking to be blocked, while still enabling legitimate uses of third-party cookies.

  You can create a partitioned cookie by passing `partitioned: true` when setting a cookie. Note that partitioned cookies must also be set with `secure: true`:

  ```js
  Astro.cookies.set('my-cookie', 'value', {
    partitioned: true,
    secure: true,
  });
  ```

  For more information, see the [`AstroCookieSetOptions` API reference](https://docs.astro.build/en/reference/api-reference/#astrocookiesetoptions).

- [#15022](https://github.com/withastro/astro/pull/15022) [`f1fce0e`](https://github.com/withastro/astro/commit/f1fce0e7cc3c1122bf5c4f1c5985ca716c8417db) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds a new `retainBody` option to the `glob()` loader to allow reducing the size of the data store.

  Currently, the `glob()` loader stores the raw body of each content file in the entry, in addition to the rendered HTML.

  The `retainBody` option defaults to `true`, but you can set it to `false` to prevent the raw body of content files from being stored in the data store. This significantly reduces the deployed size of the data store and helps avoid hitting size limits for sites with very large collections.

  The rendered body will still be available in the `entry.rendered.html` property for markdown files, and the `entry.filePath` property will still point to the original file.

  ```js
  import { defineCollection } from 'astro:content';
  import { glob } from 'astro/loaders';

  const blog = defineCollection({
    loader: glob({
      pattern: '**/*.md',
      base: './src/content/blog',
      retainBody: false,
    }),
  });
  ```

  When `retainBody` is `false`, `entry.body` will be `undefined` instead of containing the raw file contents.

- [#15153](https://github.com/withastro/astro/pull/15153) [`928529f`](https://github.com/withastro/astro/commit/928529f824d37e9bfb297ff931ebfcb3f0b56428) Thanks [@jcayzac](https://github.com/jcayzac)! - Adds a new `background` property to the `<Image />` component.

  This optional property lets you pass a background color to flatten the image with. By default, Sharp uses a black background when flattening an image that is being converted to a format that does not support transparency (e.g. `jpeg`). Providing a value for `background` on an `<Image />` component, or passing it to the `getImage()` helper, will flatten images using that color instead.

  This is especially useful when the requested output format doesn't support an alpha channel (e.g. `jpeg`) and can't support transparent backgrounds.

  ```astro
  ---
  import { Image } from 'astro:assets';
  ---

  <Image
    src="/transparent.png"
    alt="A JPEG with a white background!"
    format="jpeg"
    background="#ffffff"
  />
  ```

  See more about this new property in [the image reference docs](https://docs.astro.build/en/reference/modules/astro-assets/#background)

- [#15015](https://github.com/withastro/astro/pull/15015) [`54f6006`](https://github.com/withastro/astro/commit/54f6006c3ddae8935a5550e2c3b38d25bf662ea6) Thanks [@tony](https://github.com/tony)! - Adds optional `placement` config option for the dev toolbar.

  You can now configure the default toolbar position (`'bottom-left'`, `'bottom-center'`, or `'bottom-right'`) via `devToolbar.placement` in your Astro config. This option is helpful for sites with UI elements (chat widgets, cookie banners) that are consistently obscured by the toolbar in the dev environment.

  You can set a project default that is consistent across environments (e.g. dev machines, browser instances, team members):

  ```js
  // astro.config.mjs
  export default defineConfig({
    devToolbar: {
      placement: 'bottom-left',
    },
  });
  ```

  User preferences from the toolbar UI (stored in `localStorage`) still take priority, so this setting can be overridden in individual situations as necessary.

### Patch Changes

- [#15213](https://github.com/withastro/astro/pull/15213) [`c775fce`](https://github.com/withastro/astro/commit/c775fce98f50001bc59025dceaf8ea5287675f17) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - **BREAKING CHANGE to the experimental Fonts API only**

  Updates how the local provider must be used when using the experimental Fonts API

  Previously, there were 2 kinds of font providers: remote and local.

  Font providers are now unified. If you are using the local provider, the process for configuring local fonts must be updated:

  ```diff
  -import { defineConfig } from "astro/config";
  +import { defineConfig, fontProviders } from "astro/config";

  export default defineConfig({
      experimental: {
          fonts: [{
              name: "Custom",
              cssVariable: "--font-custom",
  -            provider: "local",
  +            provider: fontProviders.local(),
  +            options: {
              variants: [
                  {
                      weight: 400,
                      style: "normal",
                      src: ["./src/assets/fonts/custom-400.woff2"]
                  },
                  {
                      weight: 700,
                      style: "normal",
                      src: ["./src/assets/fonts/custom-700.woff2"]
                  }
                  // ...
              ]
  +            }
          }]
      }
  });
  ```

  Once configured, there is no change to using local fonts in your project. However, you should inspect your deployed site to confirm that your new font configuration is being applied.

  See [the experimental Fonts API docs](https://docs.astro.build/en/reference/experimental-flags/fonts/) for more information.

  When building a custom `FontProvider` for the experimental Fonts API, the `init()` method receives a `context`. This context now exposes a `root` URL, useful for resolving local files:

  ```diff
  import type { FontProvider } from "astro";

  export function registryFontProvider(): FontProvider {
    return {
      // ...
  -    init: async ({ storage }) => {
  +    init: async ({ storage, root }) => {
          // ...
      },
    };
  }
  ```

## 5.16.13

### Patch Changes

- [#15182](https://github.com/withastro/astro/pull/15182) [`cb60ee1`](https://github.com/withastro/astro/commit/cb60ee16051da258ab140f3bb64ff3fd8e4c9e17) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Adds a new `getFontBuffer()` method to retrieve font file buffers when using the experimental Fonts API

  The `getFontData()` helper function from `astro:assets` was introduced in 5.14.0 to provide access to font family data for use outside of Astro. One of the goals of this API was to be able to retrieve buffers using URLs.

  However, it turned out to be impactical and even impossible during prerendering.

  Astro now exports a new `getFontBuffer()` helper function from `astro:assets` to retrieve font file buffers from URL returned by `getFontData()`. For example, when using [satori](https://github.com/vercel/satori) to generate OpenGraph images:

  ```diff
  // src/pages/og.png.ts

  import type{ APIRoute } from "astro"
  -import { getFontData } from "astro:assets"
  +import { getFontData, getFontBuffer } from "astro:assets"
  import satori from "satori"

  export const GET: APIRoute = (context) => {
    const data = getFontData("--font-roboto")

    const svg = await satori(
      <div style={{ color: "black" }}>hello, world</div>,
      {
        width: 600,
        height: 400,
        fonts: [
          {
            name: "Roboto",
  -          data: await fetch(new URL(data[0].src[0].url, context.url.origin)).then(res => res.arrayBuffer()),
  +          data: await getFontBuffer(data[0].src[0].url),
            weight: 400,
            style: "normal",
          },
        ],
      },
    )

    // ...
  }
  ```

  See the [experimental Fonts API documentation](https://docs.astro.build/en/reference/experimental-flags/fonts/#accessing-font-data-programmatically) for more information.

## 5.16.12

### Patch Changes

- [#15175](https://github.com/withastro/astro/pull/15175) [`47ae148`](https://github.com/withastro/astro/commit/47ae1480eecd5da7080f1e659b6aef211aaf3300) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Allows experimental Font providers to specify family options

  Previously, an Astro `FontProvider` could only accept options at the provider level when called. That could result in weird data structures for family-specific options.

  Astro `FontProvider`s can now declare family-specific options, by specifying a generic:

  ```diff
  // font-provider.ts
  import type { FontProvider } from "astro";
  import { retrieveFonts, type Fonts } from "./utils.js",

  interface Config {
    token: string;
  }

  +interface FamilyOptions {
  +    minimal?: boolean;
  +}

  -export function registryFontProvider(config: Config): FontProvider {
  +export function registryFontProvider(config: Config): FontProvider<FamilyOptions> {
    let data: Fonts = {}

    return {
      name: "registry",
      config,
      init: async () => {
        data = await retrieveFonts(token);
      },
      listFonts: () => {
        return Object.keys(data);
      },
  -    resolveFont: ({ familyName, ...rest }) => {
  +    // options is typed as FamilyOptions
  +    resolveFont: ({ familyName, options, ...rest }) => {
        const fonts = data[familyName];
        if (fonts) {
          return { fonts };
        }
        return undefined;
      },
    };
  }
  ```

  Once the font provider is registered in the Astro config, types are automatically inferred:

  ```diff
  // astro.config.ts
  import { defineConfig } from "astro/config";
  import { registryFontProvider } from "./font-provider";

  export default defineConfig({
      experimental: {
          fonts: [{
              provider: registryFontProvider({
                token: "..."
              }),
              name: "Custom",
              cssVariable: "--font-custom",
  +            options: {
  +                minimal: true
  +            }
          }]
      }
  });
  ```

  Updates how options are passed to the Google and Google Icons font providers when using the experimental Fonts API

  Previously, the Google and Google Icons font providers accepted options that were specific to given font families.

  These options must now be set using the `options` property instead. For example using the Google provider:

  ```diff
  import { defineConfig, fontProviders } from "astro/config";

  export default defineConfig({
      experimental: {
          fonts: [{
              name: 'Inter',
              cssVariable: '--astro-font-inter',
              weights: ['300 900'],
  -            provider: fontProviders.google({
  -                experimental: {
  -                    variableAxis: {
  -                        Inter: { opsz: ['14..32'] }
  -                    }
  -                }
  -            }),
  +            provider: fontProviders.google(),
  +            options: {
  +                experimental: {
  +                    variableAxis: { opsz: ['14..32'] }
  +                }
  +            }
          }]
      }
  })
  ```

  Removes `getFontData()` exported from `astro:assets` with `fontData` when using the experimental Fonts API

  Accessing font data can be useful for advanced use cases, such as generating meta tags or Open Graph images. Before, we exposed a `getFontData()` helper function to retrieve the font data for a given `cssVariable`. That was however limiting for programmatic usages that need to access all font data.

  The `getFontData()` helper function is removed and replaced by a new `fontData` object:

  ```diff
  -import { getFontData } from "astro:assets";
  -const data = getFontData("--font-roboto")

  +import { fontData } from "astro:assets";
  +const data = fontData["--font-roboto"]

  When using `build.assetsPrefix` with a remote URL (e.g., `https://cdn.example.com`) for CSS assets, the generated `<link>` elements were incorrectly getting a `/` prepended to the full URL, resulting in invalid URLs like `/https://cdn.example.com/assets/style.css`.

  This fix checks if the stylesheet link is a remote URL before prepending the forward slash.

  Changes how font providers are implemented with updates to the `FontProvider` type

  This is an implementation detail that changes how font providers are created. This process allows Astro to take more control rather than relying directly on `unifont` types. **All of Astro's built-in font providers have been updated to reflect this new type, and can be configured as before**. However, using third-party unifont providers that rely on `unifont` types will require an update to your project code.

  Previously, an Astro `FontProvider` was made of a config and a runtime part. It relied directly on `unifont` types, which allowed a simple configuration for third-party unifont providers, but also coupled Astro's implementation to unifont, which was limiting.

  Astro's font provider implementation is now only made of a config part with dedicated hooks. This allows for the separation of config and runtime, but requires you to create a font provider object in order to use custom font providers (e.g. third-party unifont providers, or private font registeries).

  #### What should I do?

  If you were using a 3rd-party `unifont` font provider, you will now need to write an Astro `FontProvider` using it under the hood. For example:

  ```diff
  // astro.config.ts
  import { defineConfig } from "astro/config";
  import { acmeProvider, type AcmeOptions } from '@acme/unifont-provider'
  +import type { FontProvider } from "astro";
  +import type { InitializedProvider } from 'unifont';

  +function acme(config?: AcmeOptions): FontProvider {
  +	const provider = acmeProvider(config);
  +	let initializedProvider: InitializedProvider | undefined;
  +	return {
  +		name: provider._name,
  +		config,
  +		async init(context) {
  +			initializedProvider = await provider(context);
  +		},
  +		async resolveFont({ familyName, ...rest }) {
  +			return await initializedProvider?.resolveFont(familyName, rest);
  +		},
  +		async listFonts() {
  +			return await initializedProvider?.listFonts?.();
  +		},
  +	};
  +}

  export default defineConfig({
      experimental: {
          fonts: [{
  -            provider: acmeProvider({ /* ... */ }),
  +            provider: acme({ /* ... */ }),
              name: "Material Symbols Outlined",
              cssVariable: "--font-material"
          }]
      }
  });
  ```

  Changes the font format downloaded by default when using the experimental Fonts API. Additionally, adds a new `formats` configuration option to specify which font formats to download.

  Previously, Astro was opinionated about which font sources would be kept for usage, mainly keeping `woff2` and `woff` files.

  You can now specify what font formats should be downloaded (if available). Only `woff2` files are downloaded by default.

  #### What should I do?

  If you were previously relying on Astro downloading the `woff` format, you will now need to specify this explicitly with the new `formats` configuration option. Additionally, you may also specify any additional file formats to download if available:

  ```diff
  // astro.config.mjs
  import { defineConfig, fontProviders } from 'astro/config'

  export default defineConfig({
      experimental: {
          fonts: [{

### Minor Changes

- [#13880](https://github.com/withastro/astro/pull/13880) [`1a2ed01`](https://github.com/withastro/astro/commit/1a2ed01c92fe93843046396a2c854514747f4df8) Thanks [@azat-io](https://github.com/azat-io)! - Adds experimental SVGO optimization support for SVG assets

  Astro now supports automatic SVG optimization using SVGO during build time. This experimental feature helps reduce SVG file sizes while maintaining visual quality, improving your site's performance.

  To enable SVG optimization with default settings, add the following to your `astro.config.mjs`:

  ```js
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    experimental: {
      svgo: true,
    },
  });
  ```

  To customize optimization, pass a [SVGO configuration object](https://svgo.dev/docs/plugins/):

  ```js
  export default defineConfig({
    experimental: {
      svgo: {
        plugins: [
          'preset-default',
          {
            name: 'removeViewBox',
            active: false,
          },
        ],
      },
    },
  });
  ```

  For more information on enabling and using this feature in your project, see the [experimental SVG optimization docs](https://docs.astro.build/en/reference/experimental-flags/svg-optimization/).

  For example, this type can be used to retrieve the input type of a form action:

  ```ts
  import { type ActionInputSchema, defineAction } from 'astro:actions';
  import { z } from 'astro/zod';

  const action = defineAction({
    accept: 'form',
    input: z.object({ name: z.string() }),
    handler: ({ name }) => ({ message: `Welcome, ${name}!` }),
  });

  type Schema = ActionInputSchema<typeof action>;
  // typeof z.object({ name: z.string() })

  type Input = z.input<Schema>;
  // { name: string }
  ```

  Updates the default `subsets` to `["latin"]`

  Subsets have been a common source of confusion: they caused a lot of files to be downloaded by default. You now have to manually pick extra subsets.

  Review your Astro config and update subsets if you need, for example if you need greek characters:

  ```diff
  import { defineConfig, fontProviders } from "astro/config"

  export default defineConfig({
      experimental: {
          fonts: [{
              name: "Roboto",
              cssVariable: "--font-roboto",
              provider: fontProviders.google(),
  +            subsets: ["latin", "greek"]
          }]
      }
  })

- [#14750](https://github.com/withastro/astro/pull/14750) [`35122c2`](https://github.com/withastro/astro/commit/35122c278f987f9213b8e1094382398a16090aff) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Updates the experimental Fonts API to allow for more granular configuration of remote font families

  A font family is defined by a combination of properties such as weights and styles (e.g. `weights: [500, 600]` and `styles: ["normal", "bold"]`), but you may want to download only certain combinations of these.

  For greater control over which font files are downloaded, you can specify the same font (ie. with the same `cssVariable`, `name`, and `provider` properties) multiple times with different combinations. Astro will merge the results and download only the required files. For example, it is possible to download normal `500` and `600` while downloading only italic `500`:

  ```js
  // astro.config.mjs
  import { defineConfig, fontProviders } from 'astro/config';

  export default defineConfig({
    experimental: {
      fonts: [
        {
          name: 'Roboto',
          cssVariable: '--roboto',
          provider: fontProviders.google(),
          weights: [500, 600],
          styles: ['normal'],
        },
        {
          name: 'Roboto',
          cssVariable: '--roboto',
          provider: fontProviders.google(),
          weights: [500],
          styles: ['italic'],

  The `getContainerRenderer()` function is exported by Astro framework integrations to simplify the process of rendering framework components when using the experimental Container API inside a Vite or Vitest environment. This update adds the client hydration entrypoint to the returned object, enabling client-side interactivity for components rendered using this function. Previously this required users to manually call `container.addClientRenderer()` with the appropriate client renderer entrypoint.

  See [the `container-with-vitest` demo](https://github.com/withastro/astro/blob/main/examples/container-with-vitest/test/ReactWrapper.test.ts) for a usage example, and [the Container API documentation](https://docs.astro.build/en/reference/container-reference/#renderers-option) for more information on using framework components with the experimental Container API.

- [#14543](https://github.com/withastro/astro/pull/14543) [`9b3241d`](https://github.com/withastro/astro/commit/9b3241d8a903ce0092905205af883cef5498d0b2) Thanks [@matthewp](https://github.com/matthewp)! - Adds two new adapter configuration options `assetQueryParams` and `internalFetchHeaders` to the Adapter API.

  Official and community-built adapters can now use `client.assetQueryParams` to specify query parameters that should be appended to asset URLs (CSS, JavaScript, images, fonts, etc.). The query parameters are automatically appended to all generated asset URLs during the build process.

  Adapters can also use `client.internalFetchHeaders` to specify headers that should be included in Astro's internal fetch calls (Actions, View Transitions, Server Islands, Prefetch).

  This enables features like Netlify's skew protection, which requires the deploy ID to be sent with both internal requests and asset URLs to ensure client and server versions match during deployments.

- [#14489](https://github.com/withastro/astro/pull/14489) [`add4277`](https://github.com/withastro/astro/commit/add4277b6d78080a9da32554f495d870978656af) Thanks [@dev-shetty](https://github.com/dev-shetty)! - Adds a new Copy to Clipboard button to the error overlay stack trace.

  When an error occurs in dev mode, you can now copy the stack trace with a single click to more easily share it in a bug report, a support thread, or with your favorite LLM.

- [#14564](https://github.com/withastro/astro/pull/14564) [`5e7cebb`](https://github.com/withastro/astro/commit/5e7cebbfaa935dab462de6efb0bab507644e10de) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Updates `astro add cloudflare` to scaffold more configuration files

  Running `astro add cloudflare` will now emit `wrangler.jsonc` and `public/.assetsignore`, allowing your Astro project to work out of the box as a worker.

### Patch Changes

- [#14591](https://github.com/withastro/astro/pull/14591) [`3e887ec`](https://github.com/withastro/astro/commit/3e887ec523b8e4ec4d01978f0fedf246dfdfbc81) Thanks [@matthewp](https://github.com/matthewp)! - Adds TypeScript support for the `components` prop on MDX `Content` component when using `await render()`. Developers now get proper IntelliSense and type checking when passing custom components to override default MDX element rendering.

- [#14598](https://github.com/withastro/astro/pull/14598) [`7b45c65`](https://github.com/withastro/astro/commit/7b45c65c62e37d4225fb14ea378e2301de31cbea) Thanks [@delucis](https://github.com/delucis)! - Reduces terminal text styling dependency size by switching from `kleur` to `picocolors`

- [#13826](https://github.com/withastro/astro/pull/13826) [`8079482`](https://github.com/withastro/astro/commit/807948204d3838031e8952a5b3eadb26f5612b8f) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Adds the option to specify in the `preload` directive which weights, styles, or subsets to preload for a given font family when using the experimental Fonts API:

  ```astro
  ---
  import { Font } from 'astro:assets';
  ---

  <Font
    cssVariable="--font-roboto"
    preload={[{ subset: 'latin', style: 'normal' }, { weight: '400' }]}
  />
  ```

  Variable weight font files will be preloaded if any weight within its range is requested. For example, a font file for font weight `100 900` will be included when `400` is specified in a `preload` object.

The `image()` helper now normalizes bare filenames like `"cover.jpg"` to relative paths `"./cover.jpg"` for consistent resolution behavior between markdown frontmatter and JSON content collections.

## 5.14.7

### Patch Changes

- [#14582](https://github.com/withastro/astro/pull/14582) [`7958c6b`](https://github.com/withastro/astro/commit/7958c6b44c4bcdaa827d33f71ae7c2def26dc1b4) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Fixes a regression that caused Actions to throw errors while loading

- [#14566](https://github.com/withastro/astro/pull/14566) [`946fe68`](https://github.com/withastro/astro/commit/946fe68c973c966a4f589ae43858bf486cc70eb5) Thanks [@matthewp](https://github.com/matthewp)! - Fixes handling malformed cookies gracefully by returning the unparsed value instead of throwing

  When a cookie with an invalid value is present (e.g., containing invalid URI sequences), `Astro.cookies.get()` now returns the raw cookie value instead of throwing a URIError. This aligns with the behavior of the underlying `cookie` package and prevents crashes when manually-set or corrupted cookies are encountered.

### Patch Changes

- [#14562](https://github.com/withastro/astro/pull/14562) [`722bba0`](https://github.com/withastro/astro/commit/722bba0a57984b6b1c4585627cafa22af64e4251) Thanks [@erbierc](https://github.com/erbierc)! - Fixes a bug where the behavior of the "muted" HTML attribute was inconsistent with that of other attributes.

- [#14548](https://github.com/withastro/astro/pull/14548) [`6cdade4`](https://github.com/withastro/astro/commit/6cdade49c975e717f098bb4aa7f03a7b845d0a7c) Thanks [@ascorbic](https://github.com/ascorbic)! - Removes support for the `maxAge` property in `cacheHint` objects returned by live loaders.

  #### :warning: Breaking change for experimental live content collections only

  Feedback showed that this did not make sense to set at the loader level, since the loader does not know how long each individual entry should be cached for.

  If your live loader returns cache hints with `maxAge`, you need to remove this property:

  ```diff
  return {
    entries: [...],
    cacheHint: {
      tags: ['my-tag'],
  -   maxAge: 60,
      lastModified: new Date(),
    },
  };
  ```

  The `cacheHint` object now only supports `tags` and `lastModified` properties. If you want to set the max age for a page, you can set the headers manually:

  ```astro
  ---
  Astro.headers.set('cdn-cache-control', 'max-age=3600');
  ---
  ```

- [#14548](https://github.com/withastro/astro/pull/14548) [`6cdade4`](https://github.com/withastro/astro/commit/6cdade49c975e717f098bb4aa7f03a7b845d0a7c) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds missing `rendered` property to experimental live collections entry type

  Live collections support a `rendered` property that allows you to provide pre-rendered HTML for each entry. While this property was documented and implemented, it was missing from the TypeScript types. This could lead to type errors when trying to use it in a TypeScript project.

  No changes to your project code are necessary. You can continue to use the `rendered` property as before, and it will no longer produce TypeScript errors.

## 5.14.5

### Patch Changes

- [#14525](https://github.com/withastro/astro/pull/14525) [`4f55781`](https://github.com/withastro/astro/commit/4f5578190dab96ad0cd117b9e9bb96fdd18730ae) Thanks [@penx](https://github.com/penx)! - Fixes `defineLiveCollection()` types

- [#14441](https://github.com/withastro/astro/pull/14441) [`62ec8ea`](https://github.com/withastro/astro/commit/62ec8ea14a42c1dba81f68c50e987b111fabcce5) Thanks [@upsuper](https://github.com/upsuper)! - Updates redirect handling to be consistent across `static` and `server` output, aligning with the behavior of other adapters.

  Previously, the Node.js adapter used default HTML files with meta refresh tags when in `static` output. This often resulted in an extra flash of the page on redirect, while also not applying the proper status code for redirections. It's also likely less friendly to search engines.

  This update ensures that configured redirects are always handled as HTTP redirects regardless of output mode, and the default HTML files for the redirects are no longer generated in `static` output. It makes the Node.js adapter more consistent with the other official adapters.

  No change to your project is required to take advantage of this new adapter functionality. It is not expected to cause any breaking changes. However, if you relied on the previous redirecting behavior, you may need to handle your redirects differently now. Otherwise you should notice smoother redirects, with more accurate HTTP status codes, and may potentially see some SEO gains.

- [`6ee63bf`](https://github.com/withastro/astro/commit/6ee63bfac4856f21b4d4633021b3d2ee059e553f) Thanks [@matthewp](https://github.com/matthewp)! - Adds `security.allowedDomains` configuration to validate `X-Forwarded-Host` headers in SSR

  The `X-Forwarded-Host` header will now only be trusted if it matches one of the configured allowed host patterns. This prevents [host header injection attacks](https://owasp.org/www-project-web-security-testing-guide/latest/4-Web_Application_Security_Testing/07-Input_Validation_Testing/17-Testing_for_Host_Header_Injection) that can lead to cache poisoning and other security vulnerabilities.

  Configure allowed host patterns to enable `X-Forwarded-Host` support:

  ```js
  // astro.config.mjs
  export default defineConfig({
    output: 'server',
    adapter: node(),
    security: {
      allowedDomains: [
        { hostname: 'example.com' },
        { hostname: '*.example.com' },
        { hostname: 'cdn.example.com', port: '443' },
      ],
    },
  });
  ```

  The patterns support wildcards (`*` and `**`) for flexible hostname matching and can optionally specify protocol and port.

  ### Breaking change

  Previously, `Astro.url` would reflect the value of the `X-Forwarded-Host` header. While this header is commonly used by reverse proxies like Nginx to communicate the original host, it can be sent by any client, potentially allowing malicious actors to poison caches with incorrect URLs.

  If you were relying on `X-Forwarded-Host` support, add `security.allowedDomains` to your configuration to restore this functionality securely. When `allowedDomains` is not configured, `X-Forwarded-Host` headers are now ignored by default.

### Minor Changes

- [#13520](https://github.com/withastro/astro/pull/13520) [`a31edb8`](https://github.com/withastro/astro/commit/a31edb8daad8632bacd1861adf6ac720695f7173) Thanks [@openscript](https://github.com/openscript)! - Adds a new property `routePattern` available to `GetStaticPathsOptions`

  This provides the original, dynamic segment definition in a routing file path (e.g. `/[...locale]/[files]/[slug]`) from the Astro render context that would not otherwise be available within the scope of `getStaticPaths()`. This can be useful to calculate the `params` and `props` for each page route.

  For example, you can now localize your route segments and return an array of static paths by passing `routePattern` to a custom `getLocalizedData()` helper function. The `params` object will be set with explicit values for each route segment (e.g. `locale`, `files`, and `slug)`. Then, these values will be used to generate the routes and can be used in your page template via `Astro.params`.

  ```astro
  ---
  // src/pages/[...locale]/[files]/[slug].astro
  import { getLocalizedData } from '../../../utils/i18n';

  export async function getStaticPaths({ routePattern }) {
    const response = await fetch('...');
    const data = await response.json();

    console.log(routePattern); // [...locale]/[files]/[slug]

    // Call your custom helper with `routePattern` to generate the static paths
    return data.flatMap((file) => getLocalizedData(file, routePattern));
  }

  const { locale, files, slug } = Astro.params;
  ---
  ```

  For more information about this advanced routing pattern, see Astro's [routing reference](https://docs.astro.build/en/reference/routing-reference/#routepattern).

  Previously, when two dynamic routes `/[foo]` and `/[bar]` returned values on their `getStaticPaths` that resulted in the same final path, only one of the routes would be rendered while the other would be silently ignored. Now, when this happens, a warning will be displayed explaining which routes collided and on which path.

  Additionally, a new experimental flag `failOnPrerenderConflict` can be used to fail the build when such a collision occurs.

### Patch Changes

- [#13811](https://github.com/withastro/astro/pull/13811) [`69572c0`](https://github.com/withastro/astro/commit/69572c0aa2d453cc399948406dbcbfd12e03c4a8) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Adds a new `getFontData()` method to retrieve lower-level font family data programmatically when using the experimental Fonts API

  The `getFontData()` helper function from `astro:assets` provides access to font family data for use outside of Astro. This can then be used in an [API Route](/en/guides/endpoints/#server-endpoints-api-routes) or to generate your own meta tags.

  ```ts
  import { getFontData } from 'astro:assets';

  const data = getFontData('--font-roboto');
  ```

  For example, `getFontData()` can get the font buffer from the URL when using [satori](https://github.com/vercel/satori) to generate OpenGraph images:

  ```tsx
  // src/pages/og.png.ts

  import type { APIRoute } from 'astro';
  import { getFontData } from 'astro:assets';
  import satori from 'satori';

  export const GET: APIRoute = (context) => {
    const data = getFontData('--font-roboto');

      fonts: [
        {
          name: 'Roboto',

## 5.13.0

### Minor Changes

- [#14173](https://github.com/withastro/astro/pull/14173) [`39911b8`](https://github.com/withastro/astro/commit/39911b823d4617d99cc95e4b7584e9e4b7b90038) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Adds an experimental flag `staticImportMetaEnv` to disable the replacement of `import.meta.env` values with `process.env` calls and their coercion of environment variable values. This supersedes the `rawEnvValues` experimental flag, which is now removed.

  Astro allows you to configure a [type-safe schema for your environment variables](https://docs.astro.build/en/guides/environment-variables/#type-safe-environment-variables), and converts variables imported via `astro:env` into the expected type. This is the recommended way to use environment variables in Astro, as it allows you to easily see and manage whether your variables are public or secret, available on the client or only on the server at build time, and the data type of your values.

  However, you can still access environment variables through `process.env` and `import.meta.env` directly when needed. This was the only way to use environment variables in Astro before `astro:env` was added in Astro 5.0, and Astro's default handling of `import.meta.env` includes some logic that was only needed for earlier versions of Astro.

  The `experimental.staticImportMetaEnv` flag updates the behavior of `import.meta.env` to align with [Vite's handling of environment variables](https://vite.dev/guide/env-and-mode.html#env-variables) and for better ease of use with Astro's current implementations and features. **This will become the default behavior in Astro 6.0**, and this early preview is introduced as an experimental feature.

  Currently, non-public `import.meta.env` environment variables are replaced by a reference to `process.env`. Additionally, Astro may also convert the value type of your environment variables used through `import.meta.env`, which can prevent access to some values such as the strings `"true"` (which is converted to a boolean value), and `"1"` (which is converted to a number).

  The `experimental.staticImportMetaEnv` flag simplifies Astro's default behavior, making it easier to understand and use. Astro will no longer replace any `import.meta.env` environment variables with a `process.env` call, nor will it coerce values.

  To enable this feature, add the experimental flag in your Astro config and remove `rawEnvValues` if it was enabled:

  ```diff
  // astro.config.mjs
  import { defineConfig } from "astro/config";

  export default defineConfig({
  +  experimental: {
  +    staticImportMetaEnv: true
  -    rawEnvValues: false
  +  }
  });
  ```

  #### Updating your project

  If you were relying on Astro's default coercion, you may need to update your project code to apply it manually:

  ```diff
  // src/components/MyComponent.astro
  - const enabled: boolean = import.meta.env.ENABLED;
  + const enabled: boolean = import.meta.env.ENABLED === "true";
  ```

  If you were relying on the transformation into `process.env` calls, you may need to update your project code to apply it manually:

  ```diff
  // src/components/MyComponent.astro
  - const enabled: boolean = import.meta.env.DB_PASSWORD;
  + const enabled: boolean = process.env.DB_PASSWORD;
  ```

  You may also need to update types:

  ```diff
  // src/env.d.ts
  interface ImportMetaEnv {
    readonly PUBLIC_POKEAPI: string;
  -  readonly DB_PASSWORD: string;
  -  readonly ENABLED: boolean;
  +  readonly ENABLED: string;
  }

  interface ImportMeta {
    readonly env: ImportMetaEnv;
  }

  + namespace NodeJS {
  +  interface ProcessEnv {
  +    DB_PASSWORD: string;
  +  }
  + }
  ```

  See the [experimental static `import.meta.env` documentation](https://docs.astro.build/en/reference/experimental-flags/static-import-meta-env/) for more information about this feature. You can learn more about using environment variables in Astro, including `astro:env`, in the [environment variables documentation](https://docs.astro.build/en/guides/environment-variables/).

- [#14122](https://github.com/withastro/astro/pull/14122) [`41ed3ac`](https://github.com/withastro/astro/commit/41ed3ac54adf1025a38031757ee0bfaef8504092) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds experimental support for automatic [Chrome DevTools workspace folders](https://developer.chrome.com/docs/devtools/workspaces)

  This feature allows you to edit files directly in the browser and have those changes reflected in your local file system via a connected workspace folder. This allows you to apply edits such as CSS tweaks without leaving your browser tab!

  With this feature enabled, the Astro dev server will automatically configure a Chrome DevTools workspace for your project. Your project will then appear as a workspace source, ready to connect. Then, changes that you make in the "Sources" panel are automatically saved to your project source code.

  To enable this feature, add the experimental flag `chromeDevtoolsWorkspace` to your Astro config:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    experimental: {
      chromeDevtoolsWorkspace: true,
    },
  });
  ```

  See the [experimental Chrome DevTools workspace feature documentation](https://docs.astro.build/en/reference/experimental-flags/chrome-devtools-workspace/) for more information.

## 5.12.0

### Minor Changes

- [#13971](https://github.com/withastro/astro/pull/13971) [`fe35ee2`](https://github.com/withastro/astro/commit/fe35ee2835997e7e6c3e1975dc6dacfa1052a765) Thanks [@adamhl8](https://github.com/adamhl8)! - Adds an experimental flag `rawEnvValues` to disable coercion of `import.meta.env` values (e.g. converting strings to other data types) that are populated from `process.env`

  Astro allows you to configure a [type-safe schema for your environment variables](https://docs.astro.build/en/guides/environment-variables/#type-safe-environment-variables), and converts variables imported via `astro:env` into the expected type.

  However, Astro also converts your environment variables used through `import.meta.env` in some cases, and this can prevent access to some values such as the strings `"true"` (which is converted to a boolean value), and `"1"` (which is converted to a number).

  The `experimental.rawEnvValues` flag disables coercion of `import.meta.env` values that are populated from `process.env`, allowing you to use the raw value.

  To enable this feature, add the experimental flag in your Astro config:

  ```diff
  import { defineConfig } from "astro/config"

  export default defineConfig({
  +  experimental: {
  +    rawEnvValues: true,
  +  }
  })
  ```

  If you were relying on this coercion, you may need to update your project code to apply it manually:

  ```ts diff
  - const enabled: boolean = import.meta.env.ENABLED
  + const enabled: boolean = import.meta.env.ENABLED === "true"
  ```

  See the [experimental raw environment variables reference docs](https://docs.astro.build/en/reference/experimental-flags/raw-env-values/) for more information.

- [#13941](https://github.com/withastro/astro/pull/13941) [`6bd5f75`](https://github.com/withastro/astro/commit/6bd5f75806cb4df39d9e4e9b1f2225dcfdd724b0) Thanks [@aditsachde](https://github.com/aditsachde)! - Adds support for TOML files to Astro's built-in `glob()` and `file()` content loaders.

  In Astro 5.2, Astro added support for using TOML frontmatter in Markdown files instead of YAML. However, if you wanted to use TOML files as local content collection entries themselves, you needed to write your own loader.

  Astro 5.12 now directly supports loading data from TOML files in content collections in both the `glob()` and the `file()` loaders.

  If you had added your own TOML content parser for the `file()` loader, you can now remove it as this functionality is now included:

  ```diff
  // src/content.config.ts
  import { defineCollection } from "astro:content";
  import { file } from "astro/loaders";
  - import { parse as parseToml } from "toml";
  const dogs = defineCollection({
  -  loader: file("src/data/dogs.toml", { parser: (text) => parseToml(text) }),
  + loader: file("src/data/dogs.toml")
    schema: /* ... */
  })
  ```

  Note that TOML does not support top-level arrays. Instead, the `file()` loader considers each top-level table to be an independent entry. The table header is populated in the `id` field of the entry object.

  See Astro's [content collections guide](https://docs.astro.build/en/guides/content-collections/#built-in-loaders) for more information on using the built-in content loaders.

### Minor Changes

- [#13972](https://github.com/withastro/astro/pull/13972) [`db8f8be`](https://github.com/withastro/astro/commit/db8f8becc9508fa4f292d45c14af92ba59c414d1) Thanks [@ematipico](https://github.com/ematipico)! - Updates the `NodeApp.match()` function in the Adapter API to accept a second, optional parameter to allow adapter authors to add headers to static, prerendered pages.

  `NodeApp.match(request)` currently checks whether there is a route that matches the given `Request`. If there is a prerendered route, the function returns `undefined`, because static routes are already rendered and their headers cannot be updated.

  When the new, optional boolean parameter is passed (e.g. `NodeApp.match(request, true)`), Astro will return the first matched route, even when it's a prerendered route. This allows your adapter to now access static routes and provides the opportunity to set headers for these pages, for example, to implement a Content Security Policy (CSP).

  Previously, live collections required a `type` and `loader` configured. Now, Astro can determine that your collection is a `live` collection without defining it explicitly.

  This means it is now safe to remove `type: 'live'` from your collections defined in `src/live.config.ts`:

  ```diff
  import { defineLiveCollection } from 'astro:content';
  import { storeLoader } from '@mystore/astro-loader';

  const products = defineLiveCollection({
  -  type: 'live',
    loader: storeLoader({
      apiKey: process.env.STORE_API_KEY,
      endpoint: 'https://api.mystore.com/v1',
    }),
  });

  export const collections = { products };
  ```

  This is not a breaking change: your existing live collections will continue to work even if you still include `type: 'live'`. However, we suggest removing this line at your earliest convenience for future compatibility when the feature becomes stable and this config option may be removed entirely.

## 5.10.0

### Minor Changes

- [#13917](https://github.com/withastro/astro/pull/13917) [`e615216`](https://github.com/withastro/astro/commit/e615216c55bca5d61b8c5c1b49d62671f0238509) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds a new `priority` attribute for Astro's image components.

  This change introduces a new `priority` option for the `<Image />` and `<Picture />` components, which automatically sets the `loading`, `decoding`, and `fetchpriority` attributes to their optimal values for above-the-fold images which should be loaded immediately.

  It is a boolean prop, and you can use the shorthand syntax by simply adding `priority` as a prop to the `<Image />` or `<Picture />` component. When set, it will apply the following attributes:
  - `loading="eager"`
  - `decoding="sync"`
  - `fetchpriority="high"`

  The individual attributes can still be set manually if you need to customize your images further.

  By default, the Astro [`<Image />` component](https://docs.astro.build/en/guides/images/#display-optimized-images-with-the-image--component) generates `<img>` tags that lazy-load their content by setting `loading="lazy"` and `decoding="async"`. This improves performance by deferring the loading of images that are not immediately visible in the viewport, and gives the best scores in performance audits like Lighthouse.

  The new `priority` attribute will override those defaults and automatically add the best settings for your high-priority assets.

  This option was previously available for experimental responsive images, but now it is a standard feature for all images.

  #### Usage

  ```astro
  <Image src="/path/to/image.jpg" alt="An example image" priority />
  ```

  > [!Note]
  > You should only use the `priority` option for images that are critical to the initial rendering of the page, and ideally only one image per page. This is often an image identified as the [LCP element](https://web.dev/articles/lcp) when running Lighthouse tests. Using it for too many images will lead to performance issues, as it forces the browser to load those images immediately, potentially blocking the rendering of other content.

- [#13917](https://github.com/withastro/astro/pull/13917) [`e615216`](https://github.com/withastro/astro/commit/e615216c55bca5d61b8c5c1b49d62671f0238509) Thanks [@ascorbic](https://github.com/ascorbic)! - The responsive images feature introduced behind a flag in [v5.0.0](https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#500) is no longer experimental and is available for general use.

  The new responsive images feature in Astro automatically generates optimized images for different screen sizes and resolutions, and applies the correct attributes to ensure that images are displayed correctly on all devices.

  Enable the `image.responsiveStyles` option in your Astro config. Then, set a `layout` attribute on any <Image /> or <Picture /> component, or configure a default `image.layout`, for instantly responsive images with automatically generated `srcset` and `sizes` attributes based on the image's dimensions and the layout type.

  Displaying images correctly on the web can be challenging, and is one of the most common performance issues seen in sites. This new feature simplifies the most challenging part of the process: serving your site visitor an image optimized for their viewing experience, and for your website's performance.

  For full details, see the updated [Image guide](https://docs.astro.build/en/guides/images/#responsive-image-behavior).

  #### Migration from Experimental Responsive Images

  The `experimental.responsiveImages` flag has been removed, and all experimental image configuration options have been renamed to their final names.

  If you were using the experimental responsive images feature, you'll need to update your configuration:

  ##### Remove the experimental flag

  ```diff
  export default defineConfig({
     experimental: {
  -    responsiveImages: true,
     },
  });
  ```

  ##### Update image configuration options

  During the experimental phase, default styles were applied automatically to responsive images. Now, you need to explicitly set the `responsiveStyles` option to `true` if you want these styles applied.

  ```diff
  export default defineConfig({
    image: {
  +    responsiveStyles: true,
    },
  });
  ```

  The experimental image configuration options have been renamed:

  **Before:**

  ```js
  export default defineConfig({
    image: {
      experimentalLayout: 'constrained',
      experimentalObjectFit: 'cover',
      experimentalObjectPosition: 'center',
      experimentalBreakpoints: [640, 750, 828, 1080, 1280],
      experimentalDefaultStyles: true,
    },
    experimental: {
      responsiveImages: true,
    },
  });
  ```

  **After:**

  ```js
  export default defineConfig({
    image: {
      layout: 'constrained',
      objectFit: 'cover',
      objectPosition: 'center',
      breakpoints: [640, 750, 828, 1080, 1280],
      responsiveStyles: true, // This is now *false* by default
    },
  });
  ```

  ##### Component usage remains the same

  The `layout`, `fit`, and `position` props on `<Image>` and `<Picture>` components work exactly the same as before:

  ```astro
  <Image
    src={myImage}
    alt="A responsive image"
    layout="constrained"
    fit="cover"
    position="center"
  />
  ```

  If you weren't using the experimental responsive images feature, no changes are required.

  Please see the [Image guide](https://docs.astro.build/en/guides/images/#responsive-image-behavior) for more information on using responsive images in Astro.

- [#13685](https://github.com/withastro/astro/pull/13685) [`3c04c1f`](https://github.com/withastro/astro/commit/3c04c1f43027e2f9be0854f65c549fa1832f622a) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds experimental support for live content collections

  Live content collections are a new type of [content collection](https://docs.astro.build/en/guides/content-collections/) that fetch their data at runtime rather than build time. This allows you to access frequently-updated data from CMSs, APIs, databases, or other sources using a unified API, without needing to rebuild your site when the data changes.

  #### Live collections vs build-time collections

  In Astro 5.0, the content layer API added support for adding diverse content sources to content collections. You can create loaders that fetch data from any source at build time, and then access it inside a page via `getEntry()` and `getCollection()`. The data is cached between builds, giving fast access and updates.

  However there is no method for updating the data store between builds, meaning any updates to the data need a full site deploy, even if the pages are rendered on-demand. This means that content collections are not suitable for pages that update frequently. Instead, today these pages tend to access the APIs directly in the frontmatter. This works, but leads to a lot of boilerplate, and means users don't benefit from the simple, unified API that content loaders offer. In most cases users tend to individually create loader libraries that they share between pages.

  Live content collections solve this problem by allowing you to create loaders that fetch data at runtime, rather than build time. This means that the data is always up-to-date, without needing to rebuild the site.

  #### How to use

  To enable live collections add the `experimental.liveContentCollections` flag to your `astro.config.mjs` file:

  ```js title="astro.config.mjs"
  {
    experimental: {
      liveContentCollections: true,
    },
  }
  ```

  Then create a new `src/live.config.ts` file (alongside your `src/content.config.ts` if you have one) to define your live collections with a [live loader](https://docs.astro.build/en/reference/experimental-flags/live-content-collections/#creating-a-live-loader) and optionally a [schema](https://docs.astro.build/en/reference/experimental-flags/live-content-collections/#using-zod-schemas) using the new `defineLiveCollection()` function from the `astro:content` module.

  ```ts title="src/live.config.ts"
  import { defineLiveCollection } from 'astro:content';
  import { storeLoader } from '@mystore/astro-loader';

  const products = defineLiveCollection({
    type: 'live',
    loader: storeLoader({
      apiKey: process.env.STORE_API_KEY,
      endpoint: 'https://api.mystore.com/v1',
    }),
  });

  export const collections = { products };
  ```

  You can then use the dedicated `getLiveCollection()` and `getLiveEntry()` functions to access your live data:

  ```astro
  ---
  import { getLiveCollection, getLiveEntry, render } from 'astro:content';

  // Get all products
  const { entries: allProducts, error } = await getLiveCollection('products');
  if (error) {
    // Handle error appropriately
    console.error(error.message);
  }

  // Get products with a filter (if supported by your loader)
  const { entries: electronics } = await getLiveCollection('products', { category: 'electronics' });

  // Get a single product by ID (string syntax)
  const { entry: product, error: productError } = await getLiveEntry('products', Astro.params.id);
  if (productError) {
    return Astro.redirect('/404');
  }

  // Get a single product with a custom query (if supported by your loader) using a filter object
  const { entry: productBySlug } = await getLiveEntry('products', { slug: Astro.params.slug });

  const { Content } = await render(product);
  ---

  <h1>{product.title}</h1>
  <Content />
  ```

  See [the docs for the experimental live content collections feature](https://docs.astro.build/en/reference/experimental-flags/live-content-collections/) for more details on how to use this feature, including how to create a live loader. Please give feedback on [the RFC PR](https://github.com/withastro/roadmap/pull/1164) if you have any suggestions or issues.

  Changes the behavior of experimental Content Security Policy (CSP) to now serve hashes differently depending on whether or not a page is prerendered:
  - Via the `<meta>` element for static pages.
  - Via the `Response` header `content-security-policy` for on-demand rendered pages.

  This new strategy allows you to add CSP content that is not supported in a `<meta>` element (e.g. `report-uri`, `frame-ancestors`, and sandbox directives) to on-demand rendered pages.

  No change to your project code is required as this is an implementation detail. However, this will result in a different HTML output for pages that are rendered on demand. Please check your production site to verify that CSP is working as intended.

- [#13926](https://github.com/withastro/astro/pull/13926) [`953a249`](https://github.com/withastro/astro/commit/953a24924eda1ea564c97d10d68c97cbbc9db7a4) Thanks [@ematipico](https://github.com/ematipico)! - Adds a new Astro Adapter Feature called `experimentalStaticHeaders` to allow your adapter to receive the `Headers` for rendered static pages.

  Adapters that enable support for this feature can access header values directly, affecting their handling of some Astro features such as Content Security Policy (CSP). For example, Astro will no longer serve the CSP `<meta http-equiv="content-security-policy">` element in static pages to adapters with this support.

  Astro will serve the value of the header inside a map that can be retrieved from the hook `astro:build:generated`. Adapters can read this mapping and use their hosting headers capabilities to create a configuration file.

  A new field called `experimentalRouteToHeaders` will contain a map of `Map<IntegrationResolvedRoute, Headers>` where the `Headers` type contains the headers emitted by the rendered static route.

  To enable support for this experimental Astro Adapter Feature, add it to your `adapterFeatures` in your adapter config:

  ```js
  // my-adapter.mjs
  export default function createIntegration() {
    return {
      name: '@example/my-adapter',
      hooks: {
        'astro:config:done': ({ setAdapter }) => {
          setAdapter({
            name: '@example/my-adapter',
            serverEntrypoint: '@example/my-adapter/server.js',
            adapterFeatures: {
              experimentalStaticHeaders: true,
            },
          });
        },
      },
    };
  }
  ```

  See the [Adapter API docs](https://docs.astro.build/en/reference/adapter-reference/#adapter-features) for more information about providing adapter features.

  - Adds conditions for route matching in `generatePath` when building fallback routes and checking for existing translated pages

  Now for a route to be matched it needs to be inside a named `[locale]` folder. This fixes an issue where `route.pattern.test()` incorrectly matched dynamic routes, causing the page to be skipped.
  - Adds conditions for route matching in `findRouteToRewrite`

  Now the requested pathname must exist in `route.distURL` for a dynamic route to match. This fixes an issue where `route.pattern.test()` incorrectly matched dynamic routes, causing the build to fail.

  Only certain resources require quotes (e.g. `'self'` but not `https://cdn.example.com`), so Astro no longer adds quotes to any resources. You must now provide the quotes yourself for resources such as `'self'` when necessary:

  ```diff

    experimental: {
      csp: {
        styleDirective: {
          resources: [

  Removes support for experimental Content Security Policy (CSP) when using the `<ClientRouter />` component for view transitions.

  It is no longer possible to enable experimental CSP while using Astro's view transitions. Support was already unstable with the `<ClientRouter />` because CSP required making its underlying implementation asynchronous. This caused breaking changes for several users and therefore, this PR removes support completely.

  If you are currently using the component for view transitions, please remove the experimental CSP flag as they cannot be used together.

  ```diff
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    experimental: {
  -   csp: true
     }
  });
  ```

  Alternatively, to continue using experimental CSP in your project, you can [consider migrating to the browser native View Transition API](https://events-3bg.pages.dev/jotter/astro-view-transitions/) and remove the `<ClientRouter />` from your project. You may be able to achieve similar results if you are not using Astro's enhancements to the native View Transitions and Navigation APIs.

  Support might be reintroduced in future releases. You can follow this experimental feature's development in [the CSP RFC](https://github.com/withastro/roadmap/blob/feat/rfc-csp/proposals/0055-csp.md).

  CSP is an important feature to provide fine-grained control over resources that can or cannot be downloaded and executed by a document. In particular, it can help protect against [cross-site scripting (XSS)](https://developer.mozilla.org/en-US/docs/Glossary/Cross-site_scripting) attacks.

  Enabling this feature adds additional security to Astro's handling of processed and bundled scripts and styles by default, and allows you to further configure these, and additional, content types. This new experimental feature has been designed to work in every Astro rendering environment (static pages, dynamic pages and single page applications), while giving you maximum flexibility and with type-safety in mind.

  It is compatible with most of Astro's features such as client islands, and server islands, although Astro's view transitions using the `<ClientRouter />` are not yet fully supported. Inline scripts are not supported out of the box, but you can provide your own hashes for external and inline scripts.

  To enable this feature, add the experimental flag in your Astro config:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    experimental: {
      csp: true,
    },
  });
  ```

  For more information on enabling and using this feature in your project, see the [Experimental CSP docs](https://docs.astro.build/en/reference/experimental-flags/csp/).

  For a complete overview, and to give feedback on this experimental API, see the [Content Security Policy RFC](https://github.com/withastro/roadmap/blob/feat/rfc-csp/proposals/0055-csp.md).

- [#13850](https://github.com/withastro/astro/pull/13850) [`1766d22`](https://github.com/withastro/astro/commit/1766d222e7bb4adb6d15090e2d6331a0d8978303) Thanks [@ascorbic](https://github.com/ascorbic)! - Provides a Markdown renderer to content loaders

  When creating a content loader, you will now have access to a `renderMarkdown` function that allows you to render Markdown content directly within your loaders. It uses the same settings and plugins as the renderer used for Markdown files in Astro, and follows any Markdown settings you have configured in your Astro project.

  This allows you to render Markdown content from various sources, such as a CMS or other data sources, directly in your loaders without needing to preprocess the Markdown content separately.

  ```ts
  import type { Loader } from 'astro/loaders';
  import { loadFromCMS } from './cms';

  export function myLoader(settings): Loader {
    return {
      name: 'my-loader',
      async load({ renderMarkdown, store }) {
        const entries = await loadFromCMS();

        store.clear();

        for (const entry of entries) {
          // Assume each entry has a 'content' field with markdown content
          store.set({
            id: entry.id,
            data: entry,
            rendered: await renderMarkdown(entry.content),
          });
        }
      },
    };
  }
  ```

  The return value of `renderMarkdown` is an object with two properties: `html` and `metadata`. These match the `rendered` property of content entries in content collections, so you can use them to render the content in your components or pages.

  ```astro
  ---
  import { getEntry, render } from 'astro:content';
  const entry = await getEntry('my-collection', Astro.params.id);
  const { Content } = await render(entry);
  ---

  <Content />
  ```

  For more information, see the [Content Loader API docs](https://docs.astro.build/en/reference/content-loader-reference/#rendermarkdown).

This is useful when either an warning/error isn't applicable in a specific context or the default one might conflict and confuse users.

  To do so, you can add `suppress: "all"` (to suppress both the default and custom message) or `suppress: "default"` (to only suppress the default one):

  ```ts
  setAdapter({
    name: 'my-astro-integration',
    supportedAstroFeatures: {
      staticOutput: 'stable',
      hybridOutput: 'stable',
      sharpImageService: {
        support: 'limited',
        message:
          "The sharp image service isn't available in the deploy environment, but will be used by prerendered pages on build.",
        suppress: 'default',
      },
    },
  });
  ```

  This change adds a new `image.experimentalDefaultStyles` option that allows you to disable the default styles applied to responsive images.

  When using experimental responsive images, Astro applies default styles to ensure the images resize correctly. In most cases this is what you want – and they are applied with low specificity so your own styles override them. However in some cases you may want to disable these default styles entirely. This is particularly useful when using Tailwind 4, because it uses CSS cascade layers to apply styles, making it difficult to override the default styles.

  `image.experimentalDefaultStyles` is a boolean option that defaults to `true`, so you can change it in your Astro config file like this:

  ```js
  export default {
    image: {
      experimentalDefaultStyles: false,
    },
    experimental: {
      responsiveImages: true,
    },
  };
  ```

  Node.js 18 has now reached end-of-life and should not be used. For now, Astro will continue to support Node.js 18.20.8, which is the final LTS release of Node.js 18, as well as Node.js 20 and Node.js 22 or later. We will drop support for Node.js 18 in a future release, so we recommend upgrading to Node.js 22 as soon as possible. See Astro's [Node.js support policy](https://docs.astro.build/en/upgrade-astro/#support) for more details.

  :warning: **Important note for users of Cloudflare Pages**: The current build image for Cloudflare Pages uses Node.js 18.17.1 by default, which is no longer supported by Astro. If you are using Cloudflare Pages you should [override the default Node.js version](https://developers.cloudflare.com/pages/configuration/build-image/#override-default-versions) to Node.js 22. This does not affect users of Cloudflare Workers, which uses Node.js 22 by default.

  :warning: **BREAKING CHANGE FOR EXPERIMENTAL RESPONSIVE IMAGES ONLY** :warning:

  The generated styles for image layouts are now simpler and easier to override. Previously the responsive image component used CSS to set the size and aspect ratio of the images, but this is no longer needed. Now the styles just include `object-fit` and `object-position` for all images, and sets `max-width: 100%` for constrained images and `width: 100%` for full-width images.

  This is an implementation change only, and most users will see no change. However, it may affect any custom styles you have added to your responsive images. Please check your rendered images to determine whether any change to your CSS is needed.

  The styles now use the [`:where()` pseudo-class](https://developer.mozilla.org/en-US/docs/Web/CSS/:where), which has a [specificity](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_cascade/Specificity) of 0, meaning that it is easy to override with your own styles. You can now be sure that your own classes will always override the applied styles, as will global styles on `img`.

  An exception is Tailwind 4, which uses [cascade layers](https://developer.mozilla.org/en-US/docs/Web/CSS/@layer), meaning the rules are always lower specificity. Astro supports browsers that do not support cascade layers, so we cannot use this. If you need to override the styles using Tailwind 4, you must use `!important` classes. Do check if this is needed though: there may be a layout that is more appropriate for your use case.

  :warning: **BREAKING CHANGE FOR EXPERIMENTAL RESPONSIVE IMAGES ONLY** :warning:

  The layout option called `"responsive"` is renamed to `"constrained"` to better reflect its behavior.

  The previous name was causing confusion, because it is also the name of the feature. The `responsive` layout option is specifically for images that are displayed at the requested size, unless they do not fit the width of their container, at which point they would be scaled down to fit. They do not get scaled beyond the intrinsic size of the source image, or the `width` prop if provided.

  It became clear from user feedback that many people (understandably) thought that they needed to set `layout` to `responsive` if they wanted to use responsive images. They then struggled with overriding styles to make the image scale up for full-width hero images, for example, when they should have been using `full-width` layout. Renaming the layout to `constrained` should make it clearer that this layout is for when you want to constrain the maximum size of the image, but allow it to scale-down.

  #### Upgrading

  If you set a default `image.experimentalLayout` in your `astro.config.mjs`, or set it on a per-image basis using the `layout` prop, you will need to change all occurences to `constrained`:

  ```diff lang="ts"
  // astro.config.mjs
  export default {
    image: {
  -    experimentalLayout: 'responsive',
  +    experimentalLayout: 'constrained',
    },
  }
  ```

  ```diff lang="astro"
  // src/pages/index.astro
  ---
  import { Image } from 'astro:assets';
  ---
  - <Image src="/image.jpg" layout="responsive" />
  + <Image src="/image.jpg" layout="constrained" />
  ```

  Please [give feedback on the RFC](https://github.com/withastro/roadmap/pull/1051) if you have any questions or comments about the responsive images API.

## 5.7.0

### Minor Changes

- [#13527](https://github.com/withastro/astro/pull/13527) [`2fd6a6b`](https://github.com/withastro/astro/commit/2fd6a6b7aa51a4713af7fac37d5dfd824543c1bc) Thanks [@ascorbic](https://github.com/ascorbic)! - The experimental session API introduced in Astro 5.1 is now stable and ready for production use.

  Sessions are used to store user state between requests for [on-demand rendered pages](https://astro.build/en/guides/on-demand-rendering/). You can use them to store user data, such as authentication tokens, shopping cart contents, or any other data that needs to persist across requests:

  ```astro
  ---
  export const prerender = false; // Not needed with 'server' output
  const cart = await Astro.session.get('cart');
  ---

  <a href="/checkout">🛒 {cart?.length ?? 0} items</a>
  ```

  #### Configuring session storage

  Sessions require a storage driver to store the data. The Node, Cloudflare and Netlify adapters automatically configure a default driver for you, but other adapters currently require you to specify a custom storage driver in your configuration.

  If you are using an adapter that doesn't have a default driver, or if you want to choose a different driver, you can configure it using the `session` configuration option:

  ```js
  import { defineConfig } from 'astro/config';
  import vercel from '@astrojs/vercel';

  export default defineConfig({
    adapter: vercel(),
    session: {
      driver: 'upstash',
    },
  });
  ```

  #### Using sessions

  Sessions are available in on-demand rendered pages, API endpoints, actions and middleware.

  In pages and components, you can access the session using `Astro.session`:

  ```astro
  ---
  const cart = await Astro.session.get('cart');
  ---

  <a href="/checkout">🛒 {cart?.length ?? 0} items</a>
  ```

  In endpoints, actions, and middleware, you can access the session using `context.session`:

  ```js
  export async function GET(context) {
    const cart = await context.session.get('cart');
    return Response.json({ cart });
  }
  ```

  If you attempt to access the session when there is no storage driver configured, or in a prerendered page, the session object will be `undefined` and an error will be logged in the console:

  ```astro
  ---
  export const prerender = true;
  const cart = await Astro.session?.get('cart'); // Logs an error. Astro.session is undefined
  ---
  ```

  #### Upgrading from Experimental to Stable

  If you were previously using the experimental API, please remove the `experimental.session` flag from your configuration:

  ```diff
  import { defineConfig } from 'astro/config';
  import node from '@astrojs/node';

  export default defineConfig({
     adapter: node({
       mode: "standalone",
     }),
  -  experimental: {
  -    session: true,
  -  },
  });
  ```

  See [the sessions guide](https://docs.astro.build/en/guides/sessions/) for more information.

  This experimental feature allows you to use fonts from both your file system and several built-in supported providers (e.g. Google, Fontsource, Bunny) through a unified API. Keep your site performant thanks to sensible defaults and automatic optimizations including fallback font generation.

  To enable this feature, configure an `experimental.fonts` object with one or more fonts:

  ```js title="astro.config.mjs"
  import { defineConfig, fontProviders } from "astro/config"

  export default defineConfig({
      experimental: {
          fonts: [{
              provider: fontProviders.google(),
        `      name: "Roboto",
              cssVariable: "--font-roboto",
          }]
      }
  })
  ```

  Then, add a `<Font />` component and site-wide styling in your `<head>`:

  ```astro title="src/components/Head.astro"
  ---
  import { Font } from 'astro:assets';
  ---

  <Font cssVariable="--font-roboto" preload />
  <style>
    body {
      font-family: var(--font-roboto);
    }
  </style>
  ```

  Visit [the experimental Fonts documentation](https://docs.astro.build/en/reference/experimental-flags/fonts/) for the full API, how to get started, and even how to build your own custom `AstroFontProvider` if we don't yet support your preferred font service.

  For a complete overview, and to give feedback on this experimental API, see the [Fonts RFC](https://github.com/withastro/roadmap/pull/1039) and help shape its future.

  This virtual module exposes two sub-paths for type-safe, controlled access to your configuration:
  - `astro:config/client`: exposes config information that is safe to expose to the client.
  - `astro:config/server`: exposes additional information that is safe to expose to the server, such as file and directory paths.

  Access these in any file inside your project to import and use select values from your Astro config:

  ```js
  // src/utils.js
  import { trailingSlash } from 'astro:config/client';

  function addForwardSlash(path) {
    if (trailingSlash === 'always') {
      return path.endsWith('/') ? path : path + '/';
    } else {
      return path;
    }
  }
  ```

  If you were previously using this feature, please remove the experimental flag from your Astro config:

  ```diff

  export default defineConfig({
  -  experimental: {
  -    serializeConfig: true
  -  }
  })
  ```

  This feature allows you to import SVG files directly into your Astro project as components and inline them into your HTML.

  To use this feature, import an SVG file in your Astro project, passing any common SVG attributes to the imported component.

  ```astro
  ---
  import Logo from './path/to/svg/file.svg';
  ---

  <Logo width={64} height={64} fill="currentColor" />
  ```

  If you have been waiting for stabilization before using the SVG Components feature, you can now do so.

  If you were previously using this feature, please remove the experimental flag from your Astro config:

  ```diff
  import { defineConfig } from 'astro'

  export default defineConfig({
  -  experimental: {
  -    svg: true,
  -  }
  })
  ```

  Additionally, a few features that were available during the experimental stage were removed in a previous release. Please see [the v5.6.0 changelog](https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#560) for details if you have not yet already updated your project code for the experimental feature accordingly.

- [#13589](https://github.com/withastro/astro/pull/13589) [`5a0563d`](https://github.com/withastro/astro/commit/5a0563de9e377ba7b0af7e055a85893773616d4b) Thanks [@ematipico](https://github.com/ematipico)! - Deprecates the asset utility function `emitESMImage()` and adds a new `emitImageMetadata()` to be used instead

  The function
  `emitESMImage()` is now deprecated. It will continue to function, but it is no longer recommended nor supported. This function will be completely removed in a next major release of Astro.

  Please replace it with the new function`emitImageMetadata()` as soon as you are able to do so:

  ```diff
  - import { emitESMImage } from "astro/assets/utils";
  + import { emitImageMetadata } from "astro/assets/utils";
  ```

  The new function returns the same signature as the previous one. However, the new function removes two deprecated arguments that were not meant to be exposed for public use: `_watchMode` and `experimentalSvgEnabled`. Since it was possible to access these with the old function, you may need to verify that your code still works as intended with `emitImageMetadata()`.

  Deno requires npm prefix to install packages on npm. For example, to install react, we need to run `deno add npm:react`. But currently the command executed is `deno add react`, which doesn't work. So, we change the package names to have an npm prefix if you are using Deno.

## 5.6.0

### Minor Changes

- [#13403](https://github.com/withastro/astro/pull/13403) [`dcb9526`](https://github.com/withastro/astro/commit/dcb9526c6ece3b716c677205fb99b483c95bfa7d) Thanks [@yurynix](https://github.com/yurynix)! - Adds a new optional `prerenderedErrorPageFetch` option in the Adapter API to allow adapters to provide custom implementations for fetching prerendered error pages.

  Now, adapters can override the default `fetch()` behavior, for example when `fetch()` is unavailable or when you cannot call the server from itself.

  The following example provides a custom fetch for `500.html` and `404.html`, reading them from disk instead of performing an HTTP call:

  ```js "prerenderedErrorPageFetch"
  return app.render(request, {
    prerenderedErrorPageFetch: async (url: string): Promise<Response> => {
      if (url.includes("/500")) {
          const content = await fs.promises.readFile("500.html", "utf-8");
          return new Response(content, {
            status: 500,
            headers: { "Content-Type": "text/html" },
          });
      }
      const content = await fs.promises.readFile("404.html", "utf-8");
        return new Response(content, {
          status: 404,
          headers: { "Content-Type": "text/html" },
        });
  });
  ```

  If no value is provided, Astro will fallback to its default behavior for fetching error pages.

  Read more about this feature in the [Adapter API reference](https://docs.astro.build/en/reference/adapter-reference/#prerenderederrorpagefetch).

- [#13482](https://github.com/withastro/astro/pull/13482) [`ff257df`](https://github.com/withastro/astro/commit/ff257df4e1a7f3e29e9bf7f92d52bf72f7b595a4) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Updates Astro config validation to also run for the Integration API. An error log will specify which integration is failing the validation.

  Now, Astro will first validate the user configuration, then validate the updated configuration after each integration `astro:config:setup` hook has run. This means `updateConfig()` calls will no longer accept invalid configuration.

  This fixes a situation where integrations could potentially update a project with a malformed configuration. These issues should now be caught and logged so that you can update your integration to only set valid configurations.

- [#13405](https://github.com/withastro/astro/pull/13405) [`21e7e80`](https://github.com/withastro/astro/commit/21e7e8077d6f0c9ad14fe1876d87bb445f5584b1) Thanks [@Marocco2](https://github.com/Marocco2)! - Adds a new `eagerness` option for `prefetch()` when using `experimental.clientPrerender`

  With the experimental [`clientPrerender`](https://docs.astro.build/en/reference/experimental-flags/client-prerender/) flag enabled, you can use the `eagerness` option on `prefetch()` to suggest to the browser how eagerly it should prefetch/prerender link targets.

  This follows the same API described in the [Speculation Rules API](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script/type/speculationrules#eagerness) and allows you to balance the benefit of reduced wait times against bandwidth, memory, and CPU costs for your site visitors.

  For example, you can now use `prefetch()` programmatically with large sets of links and avoid [browser limits in place to guard against over-speculating](https://developer.chrome.com/blog/speculation-rules-improvements#chrome-limits) (prerendering/prefetching too many links). Set `eagerness: 'moderate'` to take advantage of [First In, First Out (FIFO)](<https://en.wikipedia.org/wiki/FIFO_(computing_and_electronics)>) strategies and browser heuristics to let the browser decide when to prerender/prefetch them and in what order:

  ```astro
  <a class="link-moderate" href="/nice-link-1">A Nice Link 1</a>
  <a class="link-moderate" href="/nice-link-2">A Nice Link 2</a>
  <a class="link-moderate" href="/nice-link-3">A Nice Link 3</a>
  <a class="link-moderate" href="/nice-link-4">A Nice Link 4</a>
  ...
  <a class="link-moderate" href="/nice-link-20">A Nice Link 20</a>
  <script>
    import { prefetch } from 'astro:prefetch';
    const linkModerate = document.getElementsByClassName('link-moderate');
    linkModerate.forEach((link) => prefetch(link.getAttribute('href'), { eagerness: 'moderate' }));
  </script>
  ```

  If an error is thrown from an integration hook, an error log will now provide information about the concerned integration and hook

### Patch Changes

- [#13539](https://github.com/withastro/astro/pull/13539) [`c43bf8c`](https://github.com/withastro/astro/commit/c43bf8cd0513c2260d4ba32b5beffe97306e2e09) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds a new `session.load()` method to the experimental session API that allows you to load a session by ID.

  When using [the experimental sessions API](https://docs.astro.build/en/reference/experimental-flags/sessions/), you don't normally need to worry about managing the session ID and cookies: Astro automatically reads the user's cookies and loads the correct session when needed. However, sometimes you need more control over which session to load.

  The new `load()` method allows you to manually load a session by ID. This is useful if you are handling the session ID yourself, or if you want to keep track of a session without using cookies. For example, you might want to restore a session from a logged-in user on another device, or work with an API endpoint that doesn't use cookies.

  ```ts
  // src/pages/api/cart.ts
  import type { APIRoute } from 'astro';

  export const GET: APIRoute = async ({ session, request }) => {
    // Load the session from a header instead of cookies
    const sessionId = request.headers.get('x-session-id');
    await session.load(sessionId);
    const cart = await session.get('cart');
    return Response.json({ cart });
  };
  ```

  If a session with that ID doesn't exist, a new one will be created. This allows you to generate a session ID in the client if needed.

  For more information, see the [experimental sessions docs](https://docs.astro.build/en/reference/experimental-flags/sessions/).

- [#13488](https://github.com/withastro/astro/pull/13488) [`d777420`](https://github.com/withastro/astro/commit/d7774207b11d042711ec310f2ad46d15246482f0) Thanks [@stramel](https://github.com/stramel)! - **BREAKING CHANGE to the experimental SVG Component API only**

  Removes some previously available prop, attribute, and configuration options from the experimental SVG API. These items are no longer available and must be removed from your code:
  - The `title` prop has been removed until we can settle on the correct balance between developer experience and accessibility. Please replace any `title` props on your components with `aria-label`:
    ```diff
    - <Logo title="My Company Logo" />
    + <Logo aria-label="My Company Logo" />
    ```
  - Sprite mode has been temporarily removed while we consider a new implementation that addresses how this feature was being used in practice. This means that there are no longer multiple `mode` options, and all SVGs will be inline. All instances of `mode` must be removed from your project as you can no longer control a mode:

    ```diff
    - <Logo mode="inline" />
    + <Logo />
    ```

    ```diff
    import { defineConfig } from 'astro'

    export default defineConfig({
      experimental: {
    -    svg: {
    -      mode: 'sprite'
    -    },
    +   svg: true
      }
    });
    ```

  - The default `role` is no longer applied due to developer feedback. Please add the appropriate `role` on each component individually as needed:
    ```diff
    - <Logo />
    + <Logo role="img" /> // To keep the role that was previously applied by default
    ```
  - The `size` prop has been removed to better work in combination with `viewBox` and additional styles/attributes. Please replace `size` with explicit `width` and `height` attributes:
    ```diff
    - <Logo size={64} />
    + <Logo width={64} height={64} />
    ```

  The new function is useful when testing routes that, for some business logic, use `Astro.rewrite`.

  For example, if you have a route `/blog/post` and for some business decision there's a rewrite to `/generic-error`, the container API implementation will look like this:

  ```js
  import Post from '../src/pages/Post.astro';
  import GenericError from '../src/pages/GenericError.astro';
  import { experimental_AstroContainer as AstroContainer } from 'astro/container';

  const container = await AstroContainer.create();
  container.insertPageRoute('/generic-error', GenericError);
  const result = await container.renderToString(Post);
  console.log(result); // this should print the response from GenericError.astro
  ```

  This new method only works for page routes, which means that endpoints aren't supported.

## 5.5.0

### Minor Changes

- [#13402](https://github.com/withastro/astro/pull/13402) [`3e7b498`](https://github.com/withastro/astro/commit/3e7b498dce52648484bb4deb04bf9e960c3d08e3) Thanks [@ematipico](https://github.com/ematipico)! - Adds a new experimental flag called `experimental.preserveScriptOrder` that renders `<script>` and `<style>` tags in the same order as they are defined.

  When rendering multiple `<style>` and `<script>` tags on the same page, Astro currently reverses their order in your generated HTML output. This can give unexpected results, for example CSS styles being overridden by earlier defined style tags when your site is built.

  With the new `preserveScriptOrder` flag enabled, Astro will generate the styles in the order they are defined:

  ```js title="astro.config.mjs"
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    experimental: {
      preserveScriptOrder: true,
    },
  });
  ```

  For example, the following component has two `<style>` tags, and both define the same style for the `body` tag:

  ```html
  <p>I am a component</p>
  <style>
    body {
      background: red;
    }
  </style>
  <style>
    body {
      background: yellow;
    }
  </style>
  ```

  Once the project is compiled, Astro will create an inline style where `yellow` appears first, and then `red`. Ultimately, the `red` background is applied:

  ```css
  body {
    background: #ff0;
  }
  body {
    background: red;
  }
  ```

  When `experimental.preserveScriptOrder` is set to `true`, the order of the two styles is kept as it is, and in the style generated `red` appears first, and then `yellow`:

  ```css
  body {
    background: red;
  }
  body {
    background: #ff0;
  }
  ```

  This is a breaking change to how Astro renders project code that contains multiple `<style>` and `<script>` tags in the same component. If you were previously compensating for Astro's behavior by writing these out of order, you will need to update your code.

  This will eventually become the new default Astro behavior, so we encourage you to add this experimental style and script ordering as soon as you are able! This will help us test the new behavior and ensure your code is ready when this becomes the new normal.

  For more information as this feature develops, please see the [experimental script order docs](https://docs.astro.build/en/reference/experimental-flags/preserve-script-order/).

- [#13352](https://github.com/withastro/astro/pull/13352) [`cb886dc`](https://github.com/withastro/astro/commit/cb886dcde6c28acca286a66be46228a4d4cc52e7) Thanks [@delucis](https://github.com/delucis)! - Adds support for a new `experimental.headingIdCompat` flag

  By default, Astro removes a trailing `-` from the end of IDs it generates for headings ending with
  special characters. This differs from the behavior of common Markdown processors.

  You can now disable this behavior with a new configuration flag:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    experimental: {
      headingIdCompat: true,
    },
  });
  ```

  This can be useful when heading IDs and anchor links need to behave consistently across your site
  and other platforms such as GitHub and npm.

  If you are [using the `rehypeHeadingIds` plugin directly](https://docs.astro.build/en/guides/markdown-content/#heading-ids-and-plugins), you can also pass this new option:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import { rehypeHeadingIds } from '@astrojs/markdown-remark';
  import { otherPluginThatReliesOnHeadingIDs } from 'some/plugin/source';

  export default defineConfig({
    markdown: {
      rehypePlugins: [
        [rehypeHeadingIds, { experimentalHeadingIdCompat: true }],
        otherPluginThatReliesOnHeadingIDs,
      ],
    },
  });
  ```

- [#13311](https://github.com/withastro/astro/pull/13311) [`a3327ff`](https://github.com/withastro/astro/commit/a3327ffbe6373228339824684eaa6f340a20a32e) Thanks [@chrisirhc](https://github.com/chrisirhc)! - Adds a new configuration option for Markdown syntax highlighting `excludeLangs`

  This option provides better support for diagramming tools that rely on Markdown code blocks, such as Mermaid.js and D2 by allowing you to exclude specific languages from Astro's default syntax highlighting.

  This option allows you to avoid rendering conflicts with tools that depend on the code not being highlighted without forcing you to disable syntax highlighting for other code blocks.

  The following example configuration will exclude highlighting for `mermaid` and `math` code blocks:

  ```js
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    markdown: {
      syntaxHighlight: {
        type: 'shiki',
        excludeLangs: ['mermaid', 'math'],
      },
    },
  });
  ```

  Read more about this new option in the [Markdown syntax highlighting configuration docs](https://docs.astro.build/en/reference/configuration-reference/#markdownsyntaxhighlight).

  You can add optional types to your session data by creating a `src/env.d.ts` file in your project that extends the global `App.SessionData` interface. For example:

  ```ts
  declare namespace App {
    interface SessionData {

        id: string;
        email: string;
      };
      lastLogin: Date;
    }
  }
  ```

  Any keys not defined in this interface will be treated as `any`.

  Then when you access `Astro.session` in your components, any defined keys will be typed correctly:

  ```astro
  ---
  const user = await Astro.session.get('user');
  //    ^? const: user: { id: string; email: string; } | undefined

  const something = await Astro.session.get('something');
  //    ^? const: something: any

  Astro.session.set('user', 1);
  //    ^? Argument of type 'number' is not assignable to parameter of type '{ id: string; email: string; }'.
  ---
  ```

  See [the experimental session docs](https://docs.astro.build/en/reference/experimental-flags/sessions/) for more information.

  **This change updates a v5.0 breaking change when `experimental.directRenderScript` became the default script handling behavior**.

  If you have already successfully upgraded to Astro v5, you may need to review your script tags again and make sure they still behave as desired after this release. [See the v5 Upgrade Guide for more details](https://docs.astro.build/en/guides/upgrade-to/v5/#script-tags-are-rendered-directly-as-declared).

## 5.4.0

### Minor Changes

- [#12052](https://github.com/withastro/astro/pull/12052) [`5be12b2`](https://github.com/withastro/astro/commit/5be12b2bc9f359d3ecfa29b766f13ed2aabd119f) Thanks [@Fryuni](https://github.com/Fryuni)! - Exposes extra APIs for scripting and testing.

  #### Config helpers

  Two new helper functions exported from `astro/config`:
  - `mergeConfig()` allows users to merge partially defined Astro configurations on top of a base config while following the merge rules of `updateConfig()` available for integrations.
  - `validateConfig()` allows users to validate that a given value is a valid Astro configuration and fills in default values as necessary.

  These helpers are particularly useful for integration authors and for developers writing scripts that need to manipulate Astro configurations programmatically.

  #### Programmatic build

  The `build` API now receives a second optional `BuildOptions` argument where users can specify:
  - `devOutput` (default `false`): output a development-based build similar to code transformed in `astro dev`.
  - `teardownCompiler` (default `true`): teardown the compiler WASM instance after build.

  These options provide more control when running Astro builds programmatically, especially for testing scenarios or custom build pipelines.

- [#13278](https://github.com/withastro/astro/pull/13278) [`4a43c4b`](https://github.com/withastro/astro/commit/4a43c4b743affb78b1502801c797157b626c77a1) Thanks [@ematipico](https://github.com/ematipico)! - Adds a new configuration option `server.allowedHosts` and CLI option `--allowed-hosts`.

  Now you can specify the hostnames that the dev and preview servers are allowed to respond to. This is useful for allowing additional subdomains, or running the dev server in a web container.

  `allowedHosts` checks the Host header on HTTP requests from browsers and if it doesn't match, it will reject the request to prevent CSRF and XSS attacks.

  ```shell
  astro dev --allowed-hosts=foo.bar.example.com,bar.example.com
  ```

  ```shell
  astro preview --allowed-hosts=foo.bar.example.com,bar.example.com
  ```

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    server: {
      allowedHosts: ['foo.bar.example.com', 'bar.example.com'],
    },
  });
  ```

  This feature is the same as [Vite's `server.allowHosts` configuration](https://vite.dev/config/server-options.html#server-allowedhosts).

- [#13254](https://github.com/withastro/astro/pull/13254) [`1e11f5e`](https://github.com/withastro/astro/commit/1e11f5e8b722b179e382f3c792cd961b2b51f61b) Thanks [@p0lyw0lf](https://github.com/p0lyw0lf)! - Adds the ability to process and optimize remote images in Markdown files

  Previously, Astro only allowed local images to be optimized when included using `![]()` syntax in plain Markdown files. Astro's image service could only display remote images without any processing.

  Now, Astro's image service can also optimize remote images written in standard Markdown syntax. This allows you to enjoy the benefits of Astro's image processing when your images are stored externally, for example in a CMS or digital asset manager.

  No additional configuration is required to use this feature! Any existing remote images written in Markdown will now automatically be optimized. To opt-out of this processing, write your images in Markdown using the HTML `<img>` tag instead. Note that images located in your `public/` folder are still never processed.

### Patch Changes

- [#13256](https://github.com/withastro/astro/pull/13256) [`509fa67`](https://github.com/withastro/astro/commit/509fa671a137515bd1818c81ee78de439a27e5dc) Thanks [@p0lyw0lf](https://github.com/p0lyw0lf)! - Adds experimental responsive image support in Markdown

  Previously, the `experimental.responsiveImages` feature could only provide responsive images when using the `<Image />` and `<Picture />` components.

  Now, images written with the `![]()` Markdown syntax in Markdown and MDX files will generate responsive images by default when using this experimental feature.

  To try this experimental feature, set `experimental.responsiveImages` to true in your `astro.config.mjs` file:

  ```js
  {
     experimental: {
        responsiveImages: true,
     },
  }
  ```

  Learn more about using this feature in the [experimental responsive images feature reference](https://docs.astro.build/en/reference/experimental-flags/responsive-images/).

  For a complete overview, and to give feedback on this experimental API, see the [Responsive Images RFC](https://github.com/withastro/roadmap/blob/responsive-images/proposals/0053-responsive-images.md).

- [#13003](https://github.com/withastro/astro/pull/13003) [`ea79054`](https://github.com/withastro/astro/commit/ea790542e186b0d2d2e828cb3ebd23bde4d04879) Thanks [@chaegumi](https://github.com/chaegumi)! - Fixes a bug that caused the `vite.base` value to be ignored when running `astro dev`

- [#13299](https://github.com/withastro/astro/pull/13299) [`2e1321e`](https://github.com/withastro/astro/commit/2e1321e9d5b27da3e86bc4021e4136661a8055aa) Thanks [@bluwy](https://github.com/bluwy)! - Uses `tinyglobby` for globbing files

- [#13233](https://github.com/withastro/astro/pull/13233) [`32fafeb`](https://github.com/withastro/astro/commit/32fafeb874cc4b6312eb50d54d9f0ca6b83aedbc) Thanks [@joshmkennedy](https://github.com/joshmkennedy)! - Ensures that `Astro.url`/`ctx.url` is correctly updated with the `base` path after rewrites.

  This change fixes an issue where `Astro.url`/`ctx.url` did not include the configured base path after Astro.rewrite was called. Now, the base path is correctly reflected in Astro.url.

  Previously, any rewrites performed through `Astro.rewrite`/`ctx.rewrite` failed to append the base path to `Astro.url`/`ctx.rewrite`, which could lead to incorrect URL handling in downstream logic. By fixing this, we ensure that all routes remain consistent and predictable after a rewrite.

  If you were relying on the work around of including the base path in astro.rewrite you can now remove it from the path.

### Minor Changes

- [#13210](https://github.com/withastro/astro/pull/13210) [`344e9bc`](https://github.com/withastro/astro/commit/344e9bc480a075161a7811b7733593556e7560da) Thanks [@VitaliyR](https://github.com/VitaliyR)! - Handle `HEAD` requests to an endpoint when a handler is not defined.

  If an endpoint defines a handler for `GET`, but does not define a handler for `HEAD`, Astro will call the `GET` handler and return the headers and status but an empty body.

- [#13195](https://github.com/withastro/astro/pull/13195) [`3b66955`](https://github.com/withastro/astro/commit/3b669555d7ab9da5427e7b7037699d4f905d3536) Thanks [@MatthewLymer](https://github.com/MatthewLymer)! - Improves SSR performance for synchronous components by avoiding the use of Promises.

- [#13145](https://github.com/withastro/astro/pull/13145) [`8d4e566`](https://github.com/withastro/astro/commit/8d4e566f5420c8a5406e1e40e8bae1c1f87cbe37) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds support for adapters auto-configuring experimental session storage drivers.

  Adapters can now configure a default session storage driver when the `experimental.session` flag is enabled. If a hosting platform has a storage primitive that can be used for session storage, the adapter can automatically configure the session storage using that driver. This allows Astro to provide a more seamless experience for users who want to use sessions without needing to manually configure the session storage.

### Patch Changes

- [#13145](https://github.com/withastro/astro/pull/13145) [`8d4e566`](https://github.com/withastro/astro/commit/8d4e566f5420c8a5406e1e40e8bae1c1f87cbe37) Thanks [@ascorbic](https://github.com/ascorbic)! - :warning: **BREAKING CHANGE FOR EXPERIMENTAL SESSIONS ONLY** :warning:

  Changes the `experimental.session` option to a boolean flag and moves session config to a top-level value. This change is to allow the new automatic session driver support. You now need to separately enable the `experimental.session` flag, and then configure the session driver using the top-level `session` key if providing manual configuration.

  ```diff
  defineConfig({
    // ...
    experimental: {
  -    session: {
  -      driver: 'upstash',
  -    },
  +    session: true,
    },
  +  session: {
  +    driver: 'upstash',
  +  },
  });
  ```

  You no longer need to configure a session driver if you are using an adapter that supports automatic session driver configuration and wish to use its default settings.

  ```diff
  defineConfig({
    adapter: node({
      mode: "standalone",
    }),
    experimental: {
  -    session: {
  -      driver: 'fs',
  -      cookie: 'astro-cookie',
  -    },
  +    session: true,
    },
  +  session: {
  +    cookie: 'astro-cookie',
  +  },
  });
  ```

  However, you can still manually configure additional driver options or choose a non-default driver to use with your adapter with the new top-level `session` config option. For more information, see the [experimental session docs](https://docs.astro.build/en/reference/experimental-flags/sessions/).

### Minor Changes

- [#12994](https://github.com/withastro/astro/pull/12994) [`5361755`](https://github.com/withastro/astro/commit/536175528dbbe75aa978d615ba2517b64bad7879) Thanks [@ascorbic](https://github.com/ascorbic)! - Redirects trailing slashes for on-demand pages

  When the `trailingSlash` option is set to `always` or `never`, on-demand rendered pages will now redirect to the correct URL when the trailing slash doesn't match the configuration option. This was previously the case for static pages, but now works for on-demand pages as well.

  Now, it doesn't matter whether your visitor navigates to `/about/`, `/about`, or even `/about///`. In production, they'll always end up on the correct page. For GET requests, the redirect will be a 301 (permanent) redirect, and for all other request methods, it will be a 308 (permanent, and preserve the request method) redirect.

  In development, you'll see a helpful 404 page to alert you of a trailing slash mismatch so you can troubleshoot routes.

- [#12979](https://github.com/withastro/astro/pull/12979) [`e621712`](https://github.com/withastro/astro/commit/e621712109b79313b24924ec4f0ba4f8ab6201c2) Thanks [@ematipico](https://github.com/ematipico)! - Adds support for redirecting to external sites with the [`redirects`](https://docs.astro.build/en/reference/configuration-reference/#redirects) configuration option.

  Now, you can redirect routes either internally to another path or externally by providing a URL beginning with `http` or `https`:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    redirects: {
      '/blog': 'https://example.com/blog',
      '/news': {
        status: 302,
        destination: 'https://example.com/news',
      },
    },
  });
  ```

- [#13084](https://github.com/withastro/astro/pull/13084) [`0f3be31`](https://github.com/withastro/astro/commit/0f3be3104e62d5b50dabfb15023f97954a160b8e) Thanks [@ematipico](https://github.com/ematipico)! - Adds a new experimental virtual module `astro:config` that exposes a type-safe subset of your `astro.config.mjs` configuration

  The virtual module exposes two sub-paths for controlled access to your configuration:
  - `astro:config/client`: exposes config information that is safe to expose to the client.
  - `astro:config/server`: exposes additional information that is safe to expose to the server, such as file/dir paths.

  To enable this new virtual module, add the `experimental.serializeManifest` feature flag to your Astro config:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  export default defineConfig({
    experimental: {
      serializeManifest: true,
    },
  });
  ```

  Then, you can access the module in any file inside your project to import and use values from your Astro config:

  ```js
  // src/utils.js
  import { trailingSlash } from 'astro:config/client';

  function addForwardSlash(path) {
    if (trailingSlash === 'always') {
      return path.endsWith('/') ? path : path + '/';
    } else {
      return path;
    }
  }
  ```

  For a complete overview, and to give feedback on this experimental API, see the [Serialized Manifest RFC](https://github.com/withastro/roadmap/blob/feat/serialised-config/proposals/0051-serialized-manifest.md).

  Sometimes a reverse proxy or similar service might modify the content-type header to include the charset or other parameters in the media type of the response. This previously wasn't handled by the client-side server island script and thus removed the script without actually placing the requested content in the DOM. This fix makes it so the script checks if the header starts with the proper content type instead of exactly matching `text/html`, so the following will still be considered a valid header: `text/html; charset=utf-8`

## 5.1.0

### Minor Changes

- [#12441](https://github.com/withastro/astro/pull/12441) [`b4fec3c`](https://github.com/withastro/astro/commit/b4fec3c7d17ed92dcaaeea5e2545aae6dfd19e53) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds experimental session support

  Sessions are used to store user state between requests for server-rendered pages, such as login status, shopping cart contents, or other user-specific data.

  ```astro
  ---
  export const prerender = false; // Not needed in 'server' mode
  const cart = await Astro.session.get('cart');
  ---

  <a href="/checkout">🛒 {cart?.length ?? 0} items</a>
  ```

  Sessions are available in on-demand rendered/SSR pages, API endpoints, actions and middleware. To enable session support, you must configure a storage driver.

  If you are using the Node.js adapter, you can use the `fs` driver to store session data on the filesystem:

  ```js
  // astro.config.mjs
  {
    adapter: node({ mode: 'standalone' }),
    experimental: {
      session: {
        // Required: the name of the unstorage driver
        driver: "fs",
      },
    },

  If you are deploying to a serverless environment, you can use drivers such as `redis`, `netlify-blobs`, `vercel-kv`, or `cloudflare-kv-binding` and optionally pass additional configuration options.

  For more information, including using the session API with other adapters and a full list of supported drivers, see [the docs for experimental session support](https://docs.astro.build/en/reference/experimental-flags/sessions/).

  Astro will now store [entity tags](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/ETag) and the [Last-Modified](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Last-Modified) date for cached remote images and use them to revalidate the cache when it goes stale.

- [#12721](https://github.com/withastro/astro/pull/12721) [`c9d5110`](https://github.com/withastro/astro/commit/c9d51107d0a4b58a9ced486b28d09118f3885254) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Adds a new `getActionPath()` helper available from `astro:actions`

  Astro 5.1 introduces a new helper function, `getActionPath()` to give you more flexibility when calling your action.

  Calling `getActionPath()` with your action returns its URL path so you can make a `fetch()` request with custom headers, or use your action with an API such as `navigator.sendBeacon()`. Then, you can [handle the custom-formatted returned data](https://docs.astro.build/en/guides/actions/#handling-returned-data) as needed, just as if you had called an action directly.

  This example shows how to call a defined `like` action passing the `Authorization` header and the [`keepalive`](https://developer.mozilla.org/en-US/docs/Web/API/Request/keepalive) option:

  ```astro
  <script>
    // src/components/my-component.astro
    import { actions, getActionPath } from 'astro:actions';

    await fetch(getActionPath(actions.like), {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        Authorization: 'Bearer YOUR_TOKEN',
      },
      body: JSON.stringify({ id: 'YOUR_ID' }),
      keepalive: true,
    });
  </script>
  ```

  This example shows how to call the same `like` action using the [`sendBeacon`](https://developer.mozilla.org/en-US/docs/Web/API/Navigator/sendBeacon) API:

  ```astro
  <script>
    // src/components/my-component.astro
    import { actions, getActionPath } from 'astro:actions';

    navigator.sendBeacon(
      getActionPath(actions.like),
      new Blob([JSON.stringify({ id: 'YOUR_ID' })], {
        type: 'application/json',
      }),
    );
  </script>
  ```

  The previously experimental feature `globalRoutePriority` is now the default in Astro 5.

  This was a refactoring of route prioritization in Astro, making it so that injected routes, file-based routes, and redirects are all prioritized using the same logic. This feature has been enabled for all Starlight projects since it was added and should not affect most users.

- [#11864](https://github.com/withastro/astro/pull/11864) [`ee38b3a`](https://github.com/withastro/astro/commit/ee38b3a94697fe883ce8300eff9f001470b8adb6) Thanks [@ematipico](https://github.com/ematipico)! - ### [changed]: `entryPoint` type inside the hook `astro:build:ssr`
  In Astro v4.x, the `entryPoint` type was `RouteData`.

  Astro v5.0 the `entryPoint` type is `IntegrationRouteData`, which contains a subset of the `RouteData` type. The fields `isIndex` and `fallbackRoutes` were removed.

  #### What should I do?

  Update your adapter to change the type of `entryPoint` from `RouteData` to `IntegrationRouteData`.

  ```diff
  -import type {RouteData} from 'astro';
  +import type {IntegrationRouteData} from "astro"

  -function useRoute(route: RouteData) {
  +function useRoute(route: IntegrationRouteData) {

  }

With this fix, the option values will now correctly resolve relative to the `outDir` option. So if `outDir` is set to `./dist/nested/`, then by default:
  - `build.client` will resolve to `<root>/dist/nested/client/`
  - `build.server` will resolve to `<root>/dist/nested/server/`

  Previously the values were incorrectly resolved:
  - `build.client` was resolved to `<root>/dist/nested/dist/client/`
  - `build.server` was resolved to `<root>/dist/nested/dist/server/`

  If you were relying on the previous build paths, make sure that your project code is updated to the new build paths.

Previously, the metadata was attached in different locations with inconsistent names. The metadata is now renamed as below:
  - `vfile.data.__astroHeadings` -> `vfile.data.astro.headings`
  - `vfile.data.imagePaths` -> `vfile.data.astro.imagePaths`

  The types of `imagePaths` has also been updated from `Set<string>` to `string[]`. The `vfile.data.astro.frontmatter` metadata is left unchanged.

  While we don't consider these APIs public, they can be accessed by Remark and Rehype plugins that want to re-use Astro's metadata. If you are using these APIs, make sure to access them in the new locations.

  Middleware, API endpoints, and pages can no longer override the `locals` object in its entirety. You can still append values onto the object, but you can not replace the entire object and delete its existing values.

  If you were previously overwriting like so:

  ```js
  ctx.locals = {
    one: 1,
    two: 2,
  };
  ```

  This can be changed to an assignment on the existing object instead:

  ```js
  Object.assign(ctx.locals, {
    one: 1,
    two: 2,
  });

This release has no changes from the latest alpha of this package, but it does bring us one step closer to the final, stable release.

  Starting from this release, no breaking changes will be introduced unless absolutely necessary.

If you have been waiting for stabilization before using `astro:env`, you can now do so.

  This feature lets you configure a type-safe schema for your environment variables, and indicate whether they should be available on the server or the client.

  To configure a schema, add the `env` option to your Astro config and define your client and server variables. If you were previously using this feature, please remove the experimental flag from your Astro config and move your entire `env` configuration unchanged to a top-level option.

  ```js
  import { defineConfig, envField } from 'astro/config';

  export default defineConfig({
    env: {
      schema: {
        API_URL: envField.string({ context: 'client', access: 'public', optional: true }),
        PORT: envField.number({ context: 'server', access: 'public', default: 4321 }),
        API_SECRET: envField.string({ context: 'server', access: 'secret' }),
      },
    },
  });
  ```

  You can import and use your defined variables from the appropriate `/client` or `/server` module:

  ```astro
  ---
  import { API_URL } from 'astro:env/client';
  import { API_SECRET_TOKEN } from 'astro:env/server';

  const data = await fetch(`${API_URL}/users`, {
    method: 'GET',
    headers: {
      'Content-Type': 'application/json',
      Authorization: `Bearer ${API_SECRET_TOKEN}`,
    },
  });
  ---

  <script>
    import { API_URL } from 'astro:env/client';

    fetch(`${API_URL}/ping`);
  </script>
  ```

  Please see our [guide to using environment variables](https://docs.astro.build/en/guides/environment-variables/#astroenv) for more about this feature.

  In Astro v4.x, the `routes` type was `RouteData`.

  Astro v5.0 the `routes` type is `IntegrationRouteData`, which contains a subset of the `RouteData` type. The fields `isIndex` and `fallbackRoutes` were removed.

  #### What should I do?

  Update your adapter to change the type of `routes` from `RouteData` to `IntegrationRouteData`.

  ```diff
  -import type {RouteData} from 'astro';
  +import type {IntegrationRouteData} from "astro"

  -function useRoute(route: RouteData) {
  +function useRoute(route: IntegrationRouteData) {

  }
  ```

- [#11941](https://github.com/withastro/astro/pull/11941) [`b6a5f39`](https://github.com/withastro/astro/commit/b6a5f39846581d0e9cfd7ae6f056c8d1209f71bd) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Merges the `output: 'hybrid'` and `output: 'static'` configurations into one single configuration (now called `'static'`) that works the same way as the previous `hybrid` option.

  It is no longer necessary to specify `output: 'hybrid'` in your Astro config to use server-rendered pages. The new `output: 'static'` has this capability included. Astro will now automatically provide the ability to opt out of prerendering in your static site with no change to your `output` configuration required. Any page route or endpoint can include `export const prerender = false` to be server-rendered, while the rest of your site is statically-generated.

  If your project used hybrid rendering, you must now remove the `output: 'hybrid'` option from your Astro config as it no longer exists. However, no other changes to your project are required, and you should have no breaking changes. The previous `'hybrid'` behavior is now the default, under a new name `'static'`.

  If you were using the `output: 'static'` (default) option, you can continue to use it as before. By default, all of your pages will continue to be prerendered and you will have a completely static site. You should have no breaking changes to your project.

  ```diff
  import { defineConfig } from "astro/config";

  export default defineConfig({
  -  output: 'hybrid',
  });
  ```

  An adapter is still required to deploy an Astro project with any server-rendered pages. Failure to include an adapter will result in a warning in development and an error at build time.

  If you had previously configured `security.checkOrigin: true`, you no longer need this set in your Astro config. This is now the default and it is safe to remove.

  To disable this behavior and opt out of automatically checking that the “origin” header matches the URL sent by each request, you must explicitly set `security.checkOrigin: false`:

  ```diff
  export default defineConfig({
  +  security: {
  +    checkOrigin: false

This allows a more direct Markdown and MDX processing, and improves the performance when building the project, but may cause issues with existing Shiki transformers.

  If you are using Shiki transformers passed to `markdown.shikiConfig.transformers`, you must make sure they do not use the `postprocess` hook as it no longer runs on code blocks in `.md` and `.mdx` files. (See [the Shiki documentation on transformer hooks](https://shiki.style/guide/transformers#transformer-hooks) for more information).

  Code blocks in `.mdoc` files and `<Code />` component do not use the internal Shiki rehype plugin and are unaffected.

  The `Astro.glob` function has been deprecated in favor of Content Collections and `import.meta.glob`.
  - If you want to query for markdown and MDX in your project, use Content Collections.
  - If you want to query source files in your project, use `import.meta.glob`(https://vitejs.dev/guide/features.html#glob-import).

  Also consider using glob packages from npm, like [fast-glob](https://www.npmjs.com/package/fast-glob), especially if statically generating your site, as it is faster for most use-cases.

  The easiest path is to migrate to `import.meta.glob` like so:

  ```diff
  - const posts = Astro.glob('./posts/*.md');
  + const posts = Object.values(import.meta.glob('./posts/*.md', { eager: true }));
  ```

  - `astro/jsx/index.js`
  - `astro/jsx/renderer.js`
  - `astro/jsx/server.js`
  - `astro/jsx/transform-options.js`

  If your project includes `.mdx` files, you must upgrade `@astrojs/mdx` to the latest version so that it doesn't rely on these entrypoints to handle your JSX.

Instead, they will be normally imported by the Node.js runtime the same way as other dependencies from `node_modules`.

  Previously, Astro would process locally-linked dependencies which were able to use Vite features like TypeScript when imported by the Astro config file.

  However, this caused confusion as integration authors may test against a package that worked locally, but not when published. This method also restricts using CJS-only dependencies because Vite requires the code to be ESM. Therefore, Astro's behaviour is now changed to ignore processing any type of dependencies by Vite.

  In most cases, make sure your locally-linked dependencies are built to JS before running the Astro project, and the config loading should work as before.

  Usage of `astro:content` in the client has always been discouraged because it leads to all of your content winding up in your client bundle, and can possibly leaks secrets.

  This formally makes doing so impossible, adding to the previous warning with errors.

  In the future Astro might add APIs for client-usage based on needs.

  Astro's default `tsconfig.json` in starter examples has been updated to include generated types and exclude your build output. This means that `src/env.d.ts` is only necessary if you have added custom type declarations or if you're not using a `tsconfig.json` file.

  Additionally, running `astro sync` no longer creates, nor updates, `src/env.d.ts` as it is not required for type-checking standard Astro projects.

  To update your project to Astro's recommended TypeScript settings, please add the following `include` and `exclude` properties to `tsconfig.json`:

  ```diff
  {
      "extends": "astro/tsconfigs/base",
  +    "include": [".astro/types.d.ts", "**/*"],

There should normally be no breaking changes, but if you relied on some previously deprecated types, these might now have been fully removed.

Also introduces the `legacy.collections` flag for projects that are unable to update to the new behavior immediately.

  :warning: **BREAKING CHANGE FOR LEGACY CONTENT COLLECTIONS** :warning:

  By default, collections that use the old types (`content` or `data`) and do not define a `loader` are now implemented under the hood using the Content Layer API's built-in `glob()` loader, with extra backward-compatibility handling.

  In order to achieve backwards compatibility with existing `content` collections, the following have been implemented:
  - a `glob` loader collection is defined, with patterns that match the previous handling (matches `src/content/<collection name>/**/*.md` and other content extensions depending on installed integrations, with underscore-prefixed files and folders ignored)
  - When used in the runtime, the entries have an ID based on the filename in the same format as legacy collections
  - A `slug` field is added with the same format as before
  - A `render()` method is added to the entry, so they can be called using `entry.render()`
  - `getEntryBySlug` is supported

  In order to achieve backwards compatibility with existing `data` collections, the following have been implemented:
  - a `glob` loader collection is defined, with patterns that match the previous handling (matches `src/content/<collection name>/**/*{.json,.yaml}` and other data extensions, with underscore-prefixed files and folders ignored)
  - Entries have an ID that is not slugified
  - `getDataEntryById` is supported

  While this backwards compatibility implementation is able to emulate most of the features of legacy collections, **there are some differences and limitations that may cause breaking changes to existing collections**:
  - In previous versions of Astro, collections would be generated for all folders in `src/content/`, even if they were not defined in `src/content/config.ts`. This behavior is now deprecated, and collections should always be defined in `src/content/config.ts`. For existing collections, these can just be empty declarations (e.g. `const blog = defineCollection({})`) and Astro will implicitly define your legacy collection for you in a way that is compatible with the new loading behavior.
  - The special `layout` field is not supported in Markdown collection entries. This property is intended only for standalone page files located in `src/pages/` and not likely to be in your collection entries. However, if you were using this property, you must now create dynamic routes that include your page styling.
  - Sort order of generated collections is non-deterministic and platform-dependent. This means that if you are calling `getCollection()`, the order in which entries are returned may be different than before. If you need a specific order, you should sort the collection entries yourself.
  - `image().refine()` is not supported. If you need to validate the properties of an image you will need to do this at runtime in your page or component.
  - the `key` argument of `getEntry(collection, key)` is typed as `string`, rather than having types for every entry.

  A new legacy configuration flag `legacy.collections` is added for users that want to keep their current legacy (content and data) collections behavior (available in Astro v2 - v4), or who are not yet ready to update their projects:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    legacy: {
      collections: true,
    },
  });
  ```

  When set, no changes to your existing collections are necessary, and the restrictions on storing both new and old collections continue to exist: legacy collections (only) must continue to remain in `src/content/`, while new collections using a loader from the Content Layer API are forbidden in that folder.

  Previously, non-boolean attributes may not have included their values when rendered to HTML. In Astro v5.0, the values are now explicitly rendered as `="true"` or `="false"`

  In the following `.astro` examples, only `allowfullscreen` is a boolean attribute:

  ```astro
  <!-- src/pages/index.astro --><!-- `allowfullscreen` is a boolean attribute -->
  <p allowfullscreen={true}></p>
  <p allowfullscreen={false}></p>

  <!-- `inherit` is *not* a boolean attribute -->
  <p inherit={true}></p>
  <p inherit={false}></p>

  <!-- `data-*` attributes are not boolean attributes -->
  <p data-light={true}></p>
  <p data-light={false}></p>
  ```

  Astro v5.0 now preserves the full data attribute with its value when rendering the HTML of non-boolean attributes:

  ```diff
    <p allowfullscreen></p>
    <p></p>

    <p inherit="true"></p>
  - <p inherit></p>
  + <p inherit="false"></p>

  - <p data-light></p>
  + <p data-light="true"></p>
  - <p></p>
  + <p data-light="false"></p>
  ```

  If you rely on attribute values, for example to locate elements or to conditionally render, update your code to match the new non-boolean attribute values:

  ```diff
  - el.getAttribute('inherit') === ''
  + el.getAttribute('inherit') === 'false'

  - el.hasAttribute('data-light')
  + el.dataset.light === 'true'
  ```

As the underlying library `libsquoosh` is no longer maintained, and the image service sees very little usage we have decided to remove it from Astro.

  Our recommendation is to use the base Sharp image service, which is more powerful, faster, and more actively maintained.

  ```diff
  - import { squooshImageService } from "astro/config";
  import { defineConfig } from "astro/config";

  export default defineConfig({
  -  image: {
  -    service: squooshImageService()
  -  }
  });
  ```

  If you are using this service, and cannot migrate to the base Sharp image service, a third-party extraction of the previous service is available here: https://github.com/Princesseuh/astro-image-service-squoosh

- [#12231](https://github.com/withastro/astro/pull/12231) [`90ae100`](https://github.com/withastro/astro/commit/90ae100cf482529828febed591172433309bc12e) Thanks [@bluwy](https://github.com/bluwy)! - Updates the automatic `charset=utf-8` behavior for Markdown pages, where instead of responding with `charset=utf-8` in the `Content-Type` header, Astro will now automatically add the `<meta charset="utf-8">` tag instead.

  This behaviour only applies to Markdown pages (`.md` or similar Markdown files located within `src/pages/`) that do not use Astro's special `layout` frontmatter property. It matches the rendering behaviour of other non-content pages, and retains the minimal boilerplate needed to write with non-ASCII characters when adding individual Markdown pages to your site.

  If your Markdown pages use the `layout` frontmatter property, then HTML encoding will be handled by the designated layout component instead, and the `<meta charset="utf-8">` tag will not be added to your page by default.

  If you require `charset=utf-8` to render your page correctly, make sure that your layout components contain the `<meta charset="utf-8">` tag. You may need to add this if you have not already done so.

  This change removes support for the `functionPerRoute` option both in Astro and `@astrojs/vercel`.

  This option made it so that each route got built as separate entrypoints so that they could be loaded as separate functions. The hope was that by doing this it would decrease the size of each function. However in practice routes use most of the same code, and increases in function size limitations made the potential upsides less important.

  Additionally there are downsides to functionPerRoute, such as hitting limits on the number of functions per project. The feature also never worked with some Astro features like i18n domains and request rewriting.

  Given this, the feature has been removed from Astro.

  In Astro v4.x, `RouteData.distURL` was `undefined` or a `URL`

  Astro v5.0, `RouteData.distURL` is `undefined` or an array of `URL`. This was a bug, because a route can generate multiple files on disk, especially when using dynamic routes such as `[slug]` or `[...slug]`.

  #### What should I do?

  Update your code to handle `RouteData.distURL` as an array.

  ```diff
  if (route.distURL) {
  -  if (route.distURL.endsWith('index.html')) {
  -    // do something
  -  }
  +  for (const url of route.distURL) {

- [#11253](https://github.com/withastro/astro/pull/11253) [`4e5cc5a`](https://github.com/withastro/astro/commit/4e5cc5aadd7d864bc5194ee67dc2ea74dbe80473) Thanks [@kevinzunigacuellar](https://github.com/kevinzunigacuellar)! - Changes the data returned for `page.url.current`, `page.url.next`, `page.url.prev`, `page.url.first` and `page.url.last` to include the value set for `base` in your Astro config.

  Previously, you had to manually prepend your configured value for `base` to the URL path. Now, Astro automatically includes your `base` value in `next` and `prev` URLs.

  If you are using the `paginate()` function for "previous" and "next" URLs, remove any existing `base` value as it is now added for you:

  ```diff
  ---
  export async function getStaticPaths({ paginate }) {
    const astronautPages = [{
      astronaut: 'Neil Armstrong',
    }, {
      astronaut: 'Buzz Aldrin',

      astronaut: 'Sally Ride',
    }, {
      astronaut: 'John Glenn',
    }];
    return paginate(astronautPages, { pageSize: 1 });
  }
  const { page } = Astro.props;
  // `base: /'docs'` configured in `astro.config.mjs`

  ### [changed]: `params` aren't decoded anymore.

  In Astro v4.x, `params` in were automatically decoded using `decodeURIComponent`.

  Astro v5.0 doesn't automatically decode `params` in `getStaticPaths` anymore, so you'll need to manually decode them yourself if needed

  #### What should I do?

  If you were relying on the automatic decode, you'll need to manually decode it using `decodeURI`.

  Note that the use of [`decodeURIComponent`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURIComponent)) is discouraged for `getStaticPaths` because it decodes more characters than it should, for example `/`, `?`, `#` and more.

  ```diff
  ---
  export function getStaticPaths() {
    return [
  +    { params: { id: decodeURI("%5Bpage%5D") } },
  -    { params: { id: "%5Bpage%5D" } },
    ]
  }

  const { id } = Astro.params;
  ---
  ```

### Minor Changes

- [#11941](https://github.com/withastro/astro/pull/11941) [`b6a5f39`](https://github.com/withastro/astro/commit/b6a5f39846581d0e9cfd7ae6f056c8d1209f71bd) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adapters can now specify the build output type they're intended for using the `adapterFeatures.buildOutput` property. This property can be used to always generate a server output, even if the project doesn't have any server-rendered pages.

  ```ts
  {
    'astro:config:done': ({ setAdapter, config }) => {
      setAdapter({
        name: 'my-adapter',
        adapterFeatures: {
          buildOutput: 'server',
        },
      });
    },
  }
  ```

  If your adapter specifies `buildOutput: 'static'`, and the user's project contains server-rendered pages, Astro will warn in development and error at build time. Note that a hybrid output, containing both static and server-rendered pages, is considered to be a `server` output, as a server is required to serve the server-rendered pages.

  This feature allows you to import SVG files directly into your Astro project as components. By default, Astro will inline the SVG content into your HTML output.

  To enable this feature, set `experimental.svg` to `true` in your Astro config:

  ```js
  {
    experimental: {
      svg: true,
    },
  }
  ```

  To use this feature, import an SVG file in your Astro project, passing any common SVG attributes to the imported component. Astro also provides a `size` attribute to set equal `height` and `width` properties:

  ```astro
  ---
  import Logo from './path/to/svg/file.svg';
  ---

  <Logo size={24} />
  ```

  For a complete overview, and to give feedback on this experimental API, see the [Feature RFC](https://github.com/withastro/roadmap/pull/1035).

Also update the `astro:build:done` hook by deprecating `routes` and adding a new `assets` map.

  When building an integration, you can now get access to routes inside the `astro:routes:resolved` hook:

  ```js
  const integration = () => {
    return {
      name: 'my-integration',
      hooks: {
        'astro:routes:resolved': ({ routes }) => {
          console.log(routes);
        },
      },
    };
  };
  ```

  This hook runs before `astro:config:done`, and whenever a route changes in development.

  The `routes` array from `astro:build:done` is now deprecated, and exposed properties are now available on `astro:routes:resolved`, except for `distURL`. For this, you can use the newly exposed `assets` map:

  ```diff
  const integration = () => {
  +    let routes
      return {
          name: 'my-integration',
          hooks: {
  +            'astro:routes:resolved': (params) => {
  +                routes = params.routes
  +            },
              'astro:build:done': ({
  -                routes
  +                assets
              }) => {
  +                for (const route of routes) {
  +                    const distURL = assets.get(route.pattern)
  +                    if (distURL) {
  +                        Object.assign(route, { distURL })
  +                    }
  +                }
                  console.log(routes)
              }
          }
      }
  }
  ```

- [#11911](https://github.com/withastro/astro/pull/11911) [`c3dce83`](https://github.com/withastro/astro/commit/c3dce8363be22121a567df22df2ec566a3ebda17) Thanks [@ascorbic](https://github.com/ascorbic)! - The Content Layer API introduced behind a flag in [4.14.0](https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#4140) is now stable and ready for use in Astro v5.0.

  The new Content Layer API builds upon content collections, taking them beyond local files in `src/content/` and allowing you to fetch content from anywhere, including remote APIs. These new collections work alongside your existing content collections, and you can migrate them to the new API at your own pace. There are significant improvements to performance with large collections of local files. For more details, see [the Content Layer RFC](https://github.com/withastro/roadmap/blob/content-layer/proposals/0050-content-layer.md).

  If you previously used this feature, you can now remove the `experimental.contentLayer` flag from your Astro config:

  ```diff
  // astro.config.mjs
  import { defineConfig } from 'astro'

  export default defineConfig({
  -  experimental: {
  -    contentLayer: true
  -  }
  })
  ```

  ### Loading your content

  The core of the new Content Layer API is the loader, a function that fetches content from a source and caches it in a local data store. Astro 4.14 ships with built-in `glob()` and `file()` loaders to handle your local Markdown, MDX, Markdoc, and JSON files:

  ```ts {3,7}
  // src/content/config.ts
  import { defineCollection, z } from 'astro:content';
  import { glob } from 'astro/loaders';

  const blog = defineCollection({
    // The ID is a slug generated from the path of the file relative to `base`
    loader: glob({ pattern: '**/*.md', base: './src/data/blog' }),
    schema: z.object({
      title: z.string(),
      description: z.string(),
      publishDate: z.coerce.date(),
    }),
  });

  export const collections = { blog };
  ```

  You can then query using the existing content collections functions, and use a simplified `render()` function to display your content:

  ```astro
  ---
  import { getEntry, render } from 'astro:content';

  const post = await getEntry('blog', Astro.params.slug);

  const { Content } = await render(entry);
  ---

  <Content />
  ```

  ### Creating a loader

  You're not restricted to the built-in loaders – we hope you'll try building your own. You can fetch content from anywhere and return an array of entries:

  ```ts
  // src/content/config.ts
  const countries = defineCollection({
    loader: async () => {
      const response = await fetch('https://restcountries.com/v3.1/all');
      const data = await response.json();
      // Must return an array of entries with an id property,
      // or an object with IDs as keys and entries as values
      return data.map((country) => ({
        id: country.cca3,
        ...country,
      }));
    },
    // optionally add a schema to validate the data and make it type-safe for users
    // schema: z.object...
  });

  export const collections = { countries };
  ```

  For more advanced loading logic, you can define an object loader. This allows incremental updates and conditional loading, and gives full access to the data store. It also allows a loader to define its own schema, including generating it dynamically based on the source API. See the [the Content Layer API RFC](https://github.com/withastro/roadmap/blob/content-layer/proposals/0050-content-layer.md#loaders) for more details.

  ### Sharing your loaders

  Loaders are better when they're shared. You can create a package that exports a loader and publish it to npm, and then anyone can use it on their site. We're excited to see what the community comes up with! To get started, [take a look at some examples](https://github.com/ascorbic/astro-loaders/). Here's how to load content using an RSS/Atom feed loader:

  ```ts
  // src/content/config.ts
  import { defineCollection } from 'astro:content';
  import { feedLoader } from '@ascorbic/feed-loader';

  const podcasts = defineCollection({
    loader: feedLoader({
      url: 'https://feeds.99percentinvisible.org/99percentinvisible',
    }),
  });

  export const collections = { podcasts };
  ```

  The `<ViewTransitions />` component has been renamed to `<ClientRouter />`. There are no other changes than the name. The old name will continue to work in Astro 5.x, but will be removed in 6.0.

  This change was done to clarify the role of the component within Astro's View Transitions support. Astro supports View Transitions APIs in a few different ways, and renaming the component makes it more clear that the features you get from the ClientRouter component are slightly different from what you get using the native CSS-based MPA router.

  We still intend to maintain the ClientRouter as before, and it's still important for use-cases that the native support doesn't cover, such as persisting state between pages.

This boolean value represents whether or not the current page is prerendered:

  ```astro

  export const prerender = true;
  ---
  ```

  ```js

- [#12047](https://github.com/withastro/astro/pull/12047) [`21b5e80`](https://github.com/withastro/astro/commit/21b5e806c5df37c6b01da63487568a6ed351ba7d) Thanks [@rgodha24](https://github.com/rgodha24)! - Adds a new optional `parser` property to the built-in `file()` loader for content collections to support additional file types such as `toml` and `csv`.

  The `file()` loader now accepts a second argument that defines a `parser` function. This allows you to specify a custom parser (e.g. `toml.parse` or `csv-parse`) to create a collection from a file's contents. The `file()` loader will automatically detect and parse JSON and YAML files (based on their file extension) with no need for a `parser`.

  This works with any type of custom file formats including `csv` and `toml`. The following example defines a content collection `dogs` using a `.toml` file.

  ```toml
  [[dogs]]
  id = "..."
  age = "..."

  [[dogs]]
  id = "..."
  age = "..."
  ```

  After importing TOML's parser, you can load the `dogs` collection into your project by passing both a file path and `parser` to the `file()` loader.

  ```typescript
  import { defineCollection } from "astro:content"
  import { file } from "astro/loaders"
  import { parse as parseToml } from "toml"

  const dogs = defineCollection({
    loader: file("src/data/dogs.toml", { parser: (text) => parseToml(text).dogs }),
    schema: /* ... */
  })

  // it also works with CSVs!
  import { parse as parseCsv } from "csv-parse/sync";

  const cats = defineCollection({
    loader: file("src/data/cats.csv", { parser: (text) => parseCsv(text, { columns: true, skipEmptyLines: true })})
  });
  ```

  The `parser` argument also allows you to load a single collection from a nested JSON document. For example, this JSON file contains multiple collections:

  ```json
  { "dogs": [{}], "cats": [{}] }
  ```

  You can separate these collections by passing a custom `parser` to the `file()` loader like so:

  ```typescript
  const dogs = defineCollection({
    loader: file('src/data/pets.json', { parser: (text) => JSON.parse(text).dogs }),
  });
  const cats = defineCollection({
    loader: file('src/data/pets.json', { parser: (text) => JSON.parse(text).cats }),
  });
  ```

  And it continues to work with maps of `id` to `data`

  ```yaml
  bubbles:
    breed: 'Goldfish'
    age: 2
  finn:
    breed: 'Betta'
    age: 1
  ```

  ```typescript
  const fish = defineCollection({
    loader: file('src/data/fish.yaml'),
    schema: z.object({ breed: z.string(), age: z.number() }),
  });
  ```

The `routePattern` represents the current route (component)
  that is being rendered by Astro. It's usually a path pattern will look like this: `blog/[slug]`:

  ```astro
  ---
  // src/pages/blog/[slug].astro
  const route = Astro.routePattern;

  This can be used to know if the user's project will be built as a static site (HTML files), or a server-rendered site (whose exact output depends on the adapter).

- [#12377](https://github.com/withastro/astro/pull/12377) [`af867f3`](https://github.com/withastro/astro/commit/af867f3910ecd8fc04a5337f591d84f03192e3fa) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds experimental support for automatic responsive images

  This feature is experimental and may change in future versions. To enable it, set `experimental.responsiveImages` to `true` in your `astro.config.mjs` file.

  ```js title=astro.config.mjs
  {
     experimental: {
        responsiveImages: true,
     },
  }
  ```

  When this flag is enabled, you can pass a `layout` prop to any `<Image />` or `<Picture />` component to create a responsive image. When a layout is set, images have automatically generated `srcset` and `sizes` attributes based on the image's dimensions and the layout type. Images with `responsive` and `full-width` layouts will have styles applied to ensure they resize according to their container.

  ```astro
  ---
  import { Image, Picture } from 'astro:assets';
  import myImage from '../assets/my_image.png';
  ---

  <Image
    src={myImage}
    alt="A description of my image."
    layout="responsive"
    width={800}
    height={600}
  />
  <Picture
    src={myImage}
    alt="A description of my image."
    layout="full-width"
    formats={['avif', 'webp', 'jpeg']}
  />
  ```

  This `<Image />` component will generate the following HTML output:

  ```html title=Output
  <img
    src="/_astro/my_image.hash3.webp"
    srcset="
      /_astro/my_image.hash1.webp  640w,
      /_astro/my_image.hash2.webp  750w,
      /_astro/my_image.hash3.webp  800w,
      /_astro/my_image.hash4.webp  828w,
      /_astro/my_image.hash5.webp 1080w,
      /_astro/my_image.hash6.webp 1280w,
      /_astro/my_image.hash7.webp 1600w
    "
    alt="A description of my image"
    sizes="(min-width: 800px) 800px, 100vw"
    loading="lazy"
    decoding="async"
    fetchpriority="auto"
    width="800"
    height="600"
    style="--w: 800; --h: 600; --fit: cover; --pos: center;"
    data-astro-image="responsive"
  />
  ```

  #### Responsive image properties

  These are additional properties available to the `<Image />` and `<Picture />` components when responsive images are enabled:
  - `layout`: The layout type for the image. Can be `responsive`, `fixed`, `full-width` or `none`. Defaults to value of `image.experimentalLayout`.
  - `fit`: Defines how the image should be cropped if the aspect ratio is changed. Values match those of CSS `object-fit`. Defaults to `cover`, or the value of `image.experimentalObjectFit` if set.
  - `position`: Defines the position of the image crop if the aspect ratio is changed. Values match those of CSS `object-position`. Defaults to `center`, or the value of `image.experimentalObjectPosition` if set.
  - `priority`: If set, eagerly loads the image. Otherwise images will be lazy-loaded. Use this for your largest above-the-fold image. Defaults to `false`.

  #### Default responsive image settings

  You can enable responsive images for all `<Image />` and `<Picture />` components by setting `image.experimentalLayout` with a default value. This can be overridden by the `layout` prop on each component.

  **Example:**

  ```js title=astro.config.mjs
  {
      image: {
        // Used for all `<Image />` and `<Picture />` components unless overridden
        experimentalLayout: 'responsive',
      },
      experimental: {
        responsiveImages: true,
      },
  }
  ```

  ```astro
  ---
  import { Image } from 'astro:assets';
  import myImage from '../assets/my_image.png';
  ---

  <Image src={myImage} alt="This will use responsive layout" width={800} height={600} />

  <Image src={myImage} alt="This will use full-width layout" layout="full-width" />

  <Image src={myImage} alt="This will disable responsive images" layout="none" />
  ```

  For a complete overview, and to give feedback on this experimental API, see the [Responsive Images RFC](https://github.com/withastro/roadmap/blob/responsive-images/proposals/0053-responsive-images.md).

- [#12150](https://github.com/withastro/astro/pull/12150) [`93351bc`](https://github.com/withastro/astro/commit/93351bc78aed8f4ecff003268bad21c3b93c2f56) Thanks [@bluwy](https://github.com/bluwy)! - Adds support for passing values other than `"production"` or `"development"` to the `--mode` flag (e.g. `"staging"`, `"testing"`, or any custom value) to change the value of `import.meta.env.MODE` or the loaded `.env` file. This allows you take advantage of Vite's [mode](https://vite.dev/guide/env-and-mode#modes) feature.

  Also adds a new `--devOutput` flag for `astro build` that will output a development-based build.

  Note that changing the `mode` does not change the kind of code transform handled by Vite and Astro:
  - In `astro dev`, Astro will transform code with debug information.
  - In `astro build`, Astro will transform code with the most optimized output and removes debug information.
  - In `astro build --devOutput` (new flag), Astro will transform code with debug information like in `astro dev`.

  This enables various usecases like:

  ```bash
  # Run the dev server connected to a "staging" API
  astro dev --mode staging

  # Build a site that connects to a "staging" API
  astro build --mode staging

  # Build a site that connects to a "production" API with additional debug information
  astro build --devOutput

  # Build a site that connects to a "testing" API
  astro build --mode testing
  ```

  The different modes can be used to load different `.env` files, e.g. `.env.staging` or `.env.production`, which can be customized for each environment, for example with different `API_URL` environment variable values.

This avoids leaking the framework name into the URL bar, which may be considered a security issue.

The content of the `message` property will be shown in the Astro CLI when the adapter is not compatible with the feature, allowing one to give a better informational message to the user.

  This is notably useful with the new `limited` value, to explain to the user why support is limited.

- [#12071](https://github.com/withastro/astro/pull/12071) [`61d248e`](https://github.com/withastro/astro/commit/61d248e581a3bebf0ec67169813fc8ae4a2182df) Thanks [@Princesseuh](https://github.com/Princesseuh)! - `astro add` no longer automatically sets `output: 'server'`. Since the default value of output now allows for server-rendered pages, it no longer makes sense to default to full server builds when you add an adapter

- [#11955](https://github.com/withastro/astro/pull/11955) [`d813262`](https://github.com/withastro/astro/commit/d8132626b05f150341c0628d6078fdd86b89aaed) Thanks [@matthewp](https://github.com/matthewp)! - [Server Islands](https://astro.build/blog/future-of-astro-server-islands/) introduced behind an experimental flag in [v4.12.0](https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#4120) is no longer experimental and is available for general use.

  Server islands are Astro's solution for highly cacheable pages of mixed static and dynamic content. They allow you to specify components that should run on the server, allowing the rest of the page to be more aggressively cached, or even generated statically.

  Turn any `.astro` component into a server island by adding the `server:defer` directive and optionally, fallback placeholder content. It will be rendered dynamically at runtime outside the context of the rest of the page, allowing you to add longer cache headers for the pages, or even prerender them.

  ```astro
  ---
  import Avatar from '../components/Avatar.astro';
  import GenericUser from '../components/GenericUser.astro';
  ---

  <header>
    <h1>Page Title</h1>
    <div class="header-right">
      <Avatar server:defer>
        <GenericUser slot="fallback" />
      </Avatar>
    </div>
  </header>
  ```

  If you were previously using this feature, please remove the experimental flag from your Astro config:

  ```diff
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    experimental {
  -    serverIslands: true,
    },
  });
  ```

  If you have been waiting for stabilization before using server islands, you can now do so.

  Please see the [server island documentation](https://docs.astro.build/en/guides/server-islands/) for more about this feature.

- [#12373](https://github.com/withastro/astro/pull/12373) [`d10f918`](https://github.com/withastro/astro/commit/d10f91815e63f169cff3d1daef5505aef077c76c) Thanks [@bholmesdev](https://github.com/bholmesdev)! - Changes the default behavior for Astro Action form requests to a standard POST submission.

  In Astro 4.x, actions called from an HTML form would trigger a redirect with the result forwarded using cookies. This caused issues for large form errors and return values that exceeded the 4 KB limit of cookie-based storage.

  Astro 5.0 now renders the result of an action as a POST result without any forwarding. This will introduce a "confirm form resubmission?" dialog when a user attempts to refresh the page, though it no longer imposes a 4 KB limit on action return value.

  ## Customize form submission behavior

  If you prefer to address the "confirm form resubmission?" dialog on refresh, or to preserve action results across sessions, you can now [customize action result handling from middleware](https://5-0-0-beta.docs.astro.build/en/guides/actions/#advanced-persist-action-results-with-a-session).

  We recommend using a session storage provider [as described in our Netlify Blob example](https://5-0-0-beta.docs.astro.build/en/guides/actions/#advanced-persist-action-results-with-a-session). However, if you prefer the cookie forwarding behavior from 4.X and accept the 4 KB size limit, you can implement the pattern as shown in this sample snippet:

  ```ts
  // src/middleware.ts
  import { defineMiddleware } from 'astro:middleware';
  import { getActionContext } from 'astro:actions';

  export const onRequest = defineMiddleware(async (context, next) => {
    // Skip requests for prerendered pages
    if (context.isPrerendered) return next();

    const { action, setActionResult, serializeActionResult } = getActionContext(context);

    // If an action result was forwarded as a cookie, set the result
    // to be accessible from `Astro.getActionResult()`
    const payload = context.cookies.get('ACTION_PAYLOAD');
    if (payload) {
      const { actionName, actionResult } = payload.json();
      setActionResult(actionName, actionResult);
      context.cookies.delete('ACTION_PAYLOAD');
      return next();
    }

    // If an action was called from an HTML form action,
    // call the action handler and redirect with the result as a cookie.
    if (action?.calledFrom === 'form') {
      const actionResult = await action.handler();

      context.cookies.set('ACTION_PAYLOAD', {
        actionName: action.name,
        actionResult: serializeActionResult(actionResult),
      });

      if (actionResult.error) {
        // Redirect back to the previous page on error
        const referer = context.request.headers.get('Referer');
        if (!referer) {
          throw new Error('Internal: Referer unexpectedly missing from Action POST request.');
        }
        return context.redirect(referer);
      }
      // Redirect to the destination page on success
      return context.redirect(context.originPathname);
    }

    return next();
  });
  ```

  The previous location is still supported, and is required if the `legacy.collections` flag is enabled.

- [#11963](https://github.com/withastro/astro/pull/11963) [`0a1036e`](https://github.com/withastro/astro/commit/0a1036eef62f13c9609362874c5b88434d1e9300) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Adds a new `createCodegenDir()` function to the `astro:config:setup` hook in the Integrations API

  In 4.14, we introduced the `injectTypes` utility on the `astro:config:done` hook. It can create `.d.ts` files and make their types available to user's projects automatically. Under the hood, it creates a file in `<root>/.astro/integrations/<normalized_integration_name>`.

  While the `.astro` directory has always been the preferred place to write code generated files, it has also been prone to mistakes. For example, you can write a `.astro/types.d.ts` file, breaking Astro types. Or you can create a file that overrides a file created by another integration.

  In this release, `<root>/.astro/integrations/<normalized_integration_name>` can now be retrieved in the `astro:config:setup` hook by calling `createCodegenDir()`. It allows you to have a dedicated folder, avoiding conflicts with another integration or Astro itself. This directory is created by calling this function so it's safe to write files to it directly:

  ```js
  import { writeFileSync } from 'node:fs';

  const integration = {
    name: 'my-integration',
    hooks: {
      'astro:config:setup': ({ createCodegenDir }) => {
        const codegenDir = createCodegenDir();
        writeFileSync(new URL('cache.json', codegenDir), '{}', 'utf-8');
      },
    },
  };
  ```

  When importing `astro/config`, types from `astro/client` will be made automatically available to your project. If your project `tsconfig.json` changes how references behave, you'll still have access to these types after running `astro sync`.

- [#12081](https://github.com/withastro/astro/pull/12081) [`8679954`](https://github.com/withastro/astro/commit/8679954bf647529e0f2134053866fc507e64c5e3) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Removes the experimental `contentCollectionsCache` introduced in `3.5.0`.

  Astro Content Layer API independently solves some of the caching and performance issues with legacy content collections that this strategy attempted to address. This feature has been replaced with continued work on improvements to the content layer. If you were using this experimental feature, you must now remove the flag from your Astro config as it no longer exists:

  ```diff
  export default defineConfig({
      experimental: {
  -        contentCollectionsCache: true
      }
  })
  ```

  The `cacheManifest` boolean argument is no longer passed to the `astro:build:done` integration hook:

  ```diff
  const integration = {
      name: "my-integration",
      hooks: {
          "astro:build:done": ({
  -            cacheManifest,
              logger
          }) => {}
      }
  }
  ```

  The signature for `app.render()` has changed, and the second argument is now an options object called `renderOptions` with more options for customizing rendering.

  The `renderOptions` are:
  - `addCookieHeader`: Determines whether Astro will set the `Set-Cookie` header, otherwise the adapter is expected to do so itself.
  - `clientAddress`: The client IP address used to set `Astro.clientAddress`.
  - `locals`: An object of locals that's set to `Astro.locals`.
  - `routeData`: An object specifying the route to use.

This can be used, for example, to register a webhook endpoint during dev, or to open a socket to a CMS to listen for changes.

  By default, `refreshContent` will refresh all collections. You can optionally pass a `loaders` property, which is an array of loader names. If provided, only collections that use those loaders will be refreshed. For example, A CMS integration could use this property to only refresh its own collections.

  You can also pass a `context` object to the loaders. This can be used to pass arbitrary data, such as the webhook body, or an event from the websocket.

  ```ts
   {
      name: 'my-integration',
      hooks: {
          'astro:server:setup': async ({ server, refreshContent }) => {
              server.middlewares.use('/_refresh', async (req, res) => {
                  if(req.method !== 'POST') {
                    res.statusCode = 405
                    res.end('Method Not Allowed');
                    return
                  }
                  let body = '';
                  req.on('data', chunk => {
                      body += chunk.toString();
                  });
                  req.on('end', async () => {
                      try {
                          const webhookBody = JSON.parse(body);
                          await refreshContent({
                            context: { webhookBody },
                            loaders: ['my-loader']
                          });
                          res.writeHead(200, { 'Content-Type': 'application/json' });
                          res.end(JSON.stringify({ message: 'Content refreshed successfully' }));

This new strategy prevents scripts from being executed in pages where they are not used.

  Scripts will directly render as declared in Astro files (including existing features like TypeScript, importing `node_modules`, and deduplicating scripts). You can also now conditionally render scripts in your Astro file.

  However, this means scripts are no longer hoisted to the `<head>`, multiple scripts on a page are no longer bundled together, and the `<script>` tag may interfere with the CSS styling.

  As this is a potentially breaking change to your script behavior, please review your `<script>` tags and ensure that they behave as expected.

  Server Island requests include the props used to render the island as well as any slots passed in (excluding the fallback slot). Since browsers have a max 4mb URL length we default to using a POST request to avoid overflowing this length.

  However in reality most usage of Server Islands are fairly isolated and won't exceed this limit, so a GET request is possible by passing this same information via search parameters.

  Using GET means we can also include a `<link rel="preload">` tag to speed up the request.

  This change implements this, with safe fallback to POST.

  This feature allows you to import SVG files directly into your Astro project as components. By default, Astro will inline the SVG content into your HTML output.

  To enable this feature, set `experimental.svg` to `true` in your Astro config:

  ```js
  {
    experimental: {
      svg: true,
    },
  }
  ```

  To use this feature, import an SVG file in your Astro project, passing any common SVG attributes to the imported component. Astro also provides a `size` attribute to set equal `height` and `width` properties:

  ```astro
  ---
  import Logo from './path/to/svg/file.svg';
  ---

  <Logo size={24} />
  ```

  For a complete overview, and to give feedback on this experimental API, see the [Feature RFC](https://github.com/withastro/roadmap/pull/1035).

- [#12329](https://github.com/withastro/astro/pull/12329) [`8309c61`](https://github.com/withastro/astro/commit/8309c61f0dfa5991d3f6c5c5fca4403794d6fda2) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Adds a new `astro:routes:resolved` hook to the Integration API. Also update the `astro:build:done` hook by deprecating `routes` and adding a new `assets` map.

  When building an integration, you can now get access to routes inside the `astro:routes:resolved` hook:

  ```js
  const integration = () => {
    return {
      name: 'my-integration',
      hooks: {
        'astro:routes:resolved': ({ routes }) => {
          console.log(routes);
        },
      },
    };
  };
  ```

  This hook runs before `astro:config:done`, and whenever a route changes in development.

  The `routes` array from `astro:build:done` is now deprecated, and exposed properties are now available on `astro:routes:resolved`, except for `distURL`. For this, you can use the newly exposed `assets` map:

  ```diff
  const integration = () => {
  +    let routes
      return {
          name: 'my-integration',
          hooks: {
  +            'astro:routes:resolved': (params) => {
  +                routes = params.routes
  +            },

- [#12377](https://github.com/withastro/astro/pull/12377) [`af867f3`](https://github.com/withastro/astro/commit/af867f3910ecd8fc04a5337f591d84f03192e3fa) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds experimental support for automatic responsive images

  This feature is experimental and may change in future versions. To enable it, set `experimental.responsiveImages` to `true` in your `astro.config.mjs` file.

  ```js title=astro.config.mjs
  {
     experimental: {
        responsiveImages: true,
     },
  }
  ```

  When this flag is enabled, you can pass a `layout` prop to any `<Image />` or `<Picture />` component to create a responsive image. When a layout is set, images have automatically generated `srcset` and `sizes` attributes based on the image's dimensions and the layout type. Images with `responsive` and `full-width` layouts will have styles applied to ensure they resize according to their container.

  ```astro
  ---
  import { Image, Picture } from 'astro:assets';
  import myImage from '../assets/my_image.png';
  ---

  <Image
    src={myImage}
    alt="A description of my image."
    layout="responsive"
    width={800}
    height={600}
  />
  <Picture
    src={myImage}
    alt="A description of my image."
    layout="full-width"
    formats={['avif', 'webp', 'jpeg']}
  />
  ```

  This `<Image />` component will generate the following HTML output:

  ```html title=Output
  <img
    src="/_astro/my_image.hash3.webp"
    srcset="
      /_astro/my_image.hash1.webp  640w,
      /_astro/my_image.hash2.webp  750w,
      /_astro/my_image.hash3.webp  800w,
      /_astro/my_image.hash4.webp  828w,
      /_astro/my_image.hash5.webp 1080w,
      /_astro/my_image.hash6.webp 1280w,
      /_astro/my_image.hash7.webp 1600w
    "
    alt="A description of my image"
    sizes="(min-width: 800px) 800px, 100vw"
    loading="lazy"
    decoding="async"
    fetchpriority="auto"
    width="800"
    height="600"
    style="--w: 800; --h: 600; --fit: cover; --pos: center;"
    data-astro-image="responsive"
  />
  ```

  #### Responsive image properties

  These are additional properties available to the `<Image />` and `<Picture />` components when responsive images are enabled:
  - `layout`: The layout type for the image. Can be `responsive`, `fixed`, `full-width` or `none`. Defaults to value of `image.experimentalLayout`.
  - `fit`: Defines how the image should be cropped if the aspect ratio is changed. Values match those of CSS `object-fit`. Defaults to `cover`, or the value of `image.experimentalObjectFit` if set.
  - `position`: Defines the position of the image crop if the aspect ratio is changed. Values match those of CSS `object-position`. Defaults to `center`, or the value of `image.experimentalObjectPosition` if set.
  - `priority`: If set, eagerly loads the image. Otherwise images will be lazy-loaded. Use this for your largest above-the-fold image. Defaults to `false`.

  #### Default responsive image settings

  You can enable responsive images for all `<Image />` and `<Picture />` components by setting `image.experimentalLayout` with a default value. This can be overridden by the `layout` prop on each component.

  **Example:**

  ```js title=astro.config.mjs
  {
      image: {
        // Used for all `<Image />` and `<Picture />` components unless overridden
        experimentalLayout: 'responsive',
      },
      experimental: {
        responsiveImages: true,
      },
  }
  ```

  ```astro
  ---
  import { Image } from 'astro:assets';
  import myImage from '../assets/my_image.png';
  ---

  <Image src={myImage} alt="This will use responsive layout" width={800} height={600} />

  <Image src={myImage} alt="This will use full-width layout" layout="full-width" />

  <Image src={myImage} alt="This will disable responsive images" layout="none" />
  ```

### Minor Changes

- [#12373](https://github.com/withastro/astro/pull/12373) [`d10f918`](https://github.com/withastro/astro/commit/d10f91815e63f169cff3d1daef5505aef077c76c) Thanks [@bholmesdev](https://github.com/bholmesdev)! - Changes the default behavior for Astro Action form requests to a standard POST submission.

  In Astro 4.x, actions called from an HTML form would trigger a redirect with the result forwarded using cookies. This caused issues for large form errors and return values that exceeded the 4 KB limit of cookie-based storage.

  Astro 5.0 now renders the result of an action as a POST result without any forwarding. This will introduce a "confirm form resubmission?" dialog when a user attempts to refresh the page, though it no longer imposes a 4 KB limit on action return value.

  ## Customize form submission behavior

  If you prefer to address the "confirm form resubmission?" dialog on refresh, or to preserve action results across sessions, you can now [customize action result handling from middleware](https://5-0-0-beta.docs.astro.build/en/guides/actions/#advanced-persist-action-results-with-a-session).

  We recommend using a session storage provider [as described in our Netlify Blob example](https://5-0-0-beta.docs.astro.build/en/guides/actions/#advanced-persist-action-results-with-a-session). However, if you prefer the cookie forwarding behavior from 4.X and accept the 4 KB size limit, you can implement the pattern as shown in this sample snippet:

  ```ts
  // src/middleware.ts
  import { defineMiddleware } from 'astro:middleware';
  import { getActionContext } from 'astro:actions';

  export const onRequest = defineMiddleware(async (context, next) => {
    // Skip requests for prerendered pages
    if (context.isPrerendered) return next();

    const { action, setActionResult, serializeActionResult } = getActionContext(context);

    // If an action result was forwarded as a cookie, set the result
    // to be accessible from `Astro.getActionResult()`
    const payload = context.cookies.get('ACTION_PAYLOAD');
    if (payload) {
      const { actionName, actionResult } = payload.json();
      setActionResult(actionName, actionResult);
      context.cookies.delete('ACTION_PAYLOAD');
      return next();
    }

    // If an action was called from an HTML form action,
    // call the action handler and redirect with the result as a cookie.
    if (action?.calledFrom === 'form') {
      const actionResult = await action.handler();

      context.cookies.set('ACTION_PAYLOAD', {
        actionName: action.name,
        actionResult: serializeActionResult(actionResult),
      });

      if (actionResult.error) {
        // Redirect back to the previous page on error
        const referer = context.request.headers.get('Referer');
        if (!referer) {
          throw new Error('Internal: Referer unexpectedly missing from Action POST request.');
        }
        return context.redirect(referer);
      }
      // Redirect to the destination page on success
      return context.redirect(context.originPathname);
    }

    return next();
  });
  ```

  This behaviour only applies to Markdown pages (`.md` or similar Markdown files located within `src/pages/`) that do not use Astro's special `layout` frontmatter property. It matches the rendering behaviour of other non-content pages, and retains the minimal boilerplate needed to write with non-ASCII characters when adding individual Markdown pages to your site.

  If your Markdown pages use the `layout` frontmatter property, then HTML encoding will be handled by the designated layout component instead, and the `<meta charset="utf-8">` tag will not be added to your page by default.

  If you require `charset=utf-8` to render your page correctly, make sure that your layout components contain the `<meta charset="utf-8">` tag. You may need to add this if you have not already done so.

TypeScript will now error if a group of related configuration options do not have consistent types. For example, you will now see an error if your language set for `i18n.defaultLocale` is not one of the supported locales specified in `i18n.locales`.

- [#12150](https://github.com/withastro/astro/pull/12150) [`93351bc`](https://github.com/withastro/astro/commit/93351bc78aed8f4ecff003268bad21c3b93c2f56) Thanks [@bluwy](https://github.com/bluwy)! - Adds support for passing values other than `"production"` or `"development"` to the `--mode` flag (e.g. `"staging"`, `"testing"`, or any custom value) to change the value of `import.meta.env.MODE` or the loaded `.env` file. This allows you take advantage of Vite's [mode](https://vite.dev/guide/env-and-mode#modes) feature.

  Also adds a new `--devOutput` flag for `astro build` that will output a development-based build.

  Note that changing the `mode` does not change the kind of code transform handled by Vite and Astro:
  - In `astro dev`, Astro will transform code with debug information.
  - In `astro build`, Astro will transform code with the most optimized output and removes debug information.
  - In `astro build --devOutput` (new flag), Astro will transform code with debug information like in `astro dev`.

  This enables various usecases like:

  ```bash
  # Run the dev server connected to a "staging" API
  astro dev --mode staging

  # Build a site that connects to a "staging" API
  astro build --mode staging

  # Build a site that connects to a "production" API with additional debug information
  astro build --devOutput

  # Build a site that connects to a "testing" API
  astro build --mode testing
  ```

  The different modes can be used to load different `.env` files, e.g. `.env.staging` or `.env.production`, which can be customized for each environment, for example with different `API_URL` environment variable values.

Also introduces the `legacy.collections` flag for projects that are unable to update to the new behavior immediately.

  :warning: **BREAKING CHANGE FOR LEGACY CONTENT COLLECTIONS** :warning:

  By default, collections that use the old types (`content` or `data`) and do not define a `loader` are now implemented under the hood using the Content Layer API's built-in `glob()` loader, with extra backward-compatibility handling.

  In order to achieve backwards compatibility with existing `content` collections, the following have been implemented:
  - a `glob` loader collection is defined, with patterns that match the previous handling (matches `src/content/<collection name>/**/*.md` and other content extensions depending on installed integrations, with underscore-prefixed files and folders ignored)
  - When used in the runtime, the entries have an ID based on the filename in the same format as legacy collections
  - A `slug` field is added with the same format as before
  - A `render()` method is added to the entry, so they can be called using `entry.render()`
  - `getEntryBySlug` is supported

  In order to achieve backwards compatibility with existing `data` collections, the following have been implemented:
  - a `glob` loader collection is defined, with patterns that match the previous handling (matches `src/content/<collection name>/**/*{.json,.yaml}` and other data extensions, with underscore-prefixed files and folders ignored)
  - Entries have an ID that is not slugified
  - `getDataEntryById` is supported

  While this backwards compatibility implementation is able to emulate most of the features of legacy collections, **there are some differences and limitations that may cause breaking changes to existing collections**:
  - In previous versions of Astro, collections would be generated for all folders in `src/content/`, even if they were not defined in `src/content/config.ts`. This behavior is now deprecated, and collections should always be defined in `src/content/config.ts`. For existing collections, these can just be empty declarations (e.g. `const blog = defineCollection({})`) and Astro will implicitly define your legacy collection for you in a way that is compatible with the new loading behavior.
  - The special `layout` field is not supported in Markdown collection entries. This property is intended only for standalone page files located in `src/pages/` and not likely to be in your collection entries. However, if you were using this property, you must now create dynamic routes that include your page styling.
  - Sort order of generated collections is non-deterministic and platform-dependent. This means that if you are calling `getCollection()`, the order in which entries are returned may be different than before. If you need a specific order, you should sort the collection entries yourself.
  - `image().refine()` is not supported. If you need to validate the properties of an image you will need to do this at runtime in your page or component.
  - the `key` argument of `getEntry(collection, key)` is typed as `string`, rather than having types for every entry.

  A new legacy configuration flag `legacy.collections` is added for users that want to keep their current legacy (content and data) collections behavior (available in Astro v2 - v4), or who are not yet ready to update their projects:

  ```js
  // astro.config.mjs
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    legacy: {
      collections: true,
    },
  });
  ```

  When set, no changes to your existing collections are necessary, and the restrictions on storing both new and old collections continue to exist: legacy collections (only) must continue to remain in `src/content/`, while new collections using a loader from the Content Layer API are forbidden in that folder.

  ### [changed]: `params` aren't decoded anymore.

  In Astro v4.x, `params` in were automatically decoded using `decodeURIComponent`.

  Astro v5.0 doesn't automatically decode `params` in `getStaticPaths` anymore, so you'll need to manually decode them yourself if needed

  #### What should I do?

  If you were relying on the automatic decode, you'll need to manually decode it using `decodeURI`.

  Note that the use of [`decodeURIComponent`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURIComponent)) is discouraged for `getStaticPaths` because it decodes more characters than it should, for example `/`, `?`, `#` and more.

  ```diff
  ---
  export function getStaticPaths() {
    return [
  +    { params: { id: decodeURI("%5Bpage%5D") } },
  -    { params: { id: "%5Bpage%5D" } },
    ]
  }

  const { id } = Astro.params;

- [#12047](https://github.com/withastro/astro/pull/12047) [`21b5e80`](https://github.com/withastro/astro/commit/21b5e806c5df37c6b01da63487568a6ed351ba7d) Thanks [@rgodha24](https://github.com/rgodha24)! - Adds a new optional `parser` property to the built-in `file()` loader for content collections to support additional file types such as `toml` and `csv`.

  The `file()` loader now accepts a second argument that defines a `parser` function. This allows you to specify a custom parser (e.g. `toml.parse` or `csv-parse`) to create a collection from a file's contents. The `file()` loader will automatically detect and parse JSON and YAML files (based on their file extension) with no need for a `parser`.

  This works with any type of custom file formats including `csv` and `toml`. The following example defines a content collection `dogs` using a `.toml` file.

  ```toml
  [[dogs]]
  id = "..."
  age = "..."

  [[dogs]]
  id = "..."
  age = "..."
  ```

  After importing TOML's parser, you can load the `dogs` collection into your project by passing both a file path and `parser` to the `file()` loader.

  ```typescript
  import { defineCollection } from "astro:content"
  import { file } from "astro/loaders"
  import { parse as parseToml } from "toml"

  const dogs = defineCollection({
    loader: file("src/data/dogs.toml", { parser: (text) => parseToml(text).dogs }),
    schema: /* ... */
  })

  // it also works with CSVs!
  import { parse as parseCsv } from "csv-parse/sync";

  const cats = defineCollection({
    loader: file("src/data/cats.csv", { parser: (text) => parseCsv(text, { columns: true, skipEmptyLines: true })})
  });
  ```

  The `parser` argument also allows you to load a single collection from a nested JSON document. For example, this JSON file contains multiple collections:

  ```json
  { "dogs": [{}], "cats": [{}] }
  ```

  You can separate these collections by passing a custom `parser` to the `file()` loader like so:

  ```typescript
  const dogs = defineCollection({
    loader: file('src/data/pets.json', { parser: (text) => JSON.parse(text).dogs }),
  });
  const cats = defineCollection({
    loader: file('src/data/pets.json', { parser: (text) => JSON.parse(text).cats }),
  });
  ```

  And it continues to work with maps of `id` to `data`

  ```yaml
  bubbles:
    breed: 'Goldfish'
    age: 2
  finn:
    breed: 'Betta'
    age: 1
  ```

  ```typescript
  const fish = defineCollection({
    loader: file('src/data/fish.yaml'),
    schema: z.object({ breed: z.string(), age: z.number() }),
  });
  ```

- [#12071](https://github.com/withastro/astro/pull/12071) [`61d248e`](https://github.com/withastro/astro/commit/61d248e581a3bebf0ec67169813fc8ae4a2182df) Thanks [@Princesseuh](https://github.com/Princesseuh)! - `astro add` no longer automatically sets `output: 'server'`. Since the default value of output now allows for server-rendered pages, it no longer makes sense to default to full server builds when you add an adapter

- [#11963](https://github.com/withastro/astro/pull/11963) [`0a1036e`](https://github.com/withastro/astro/commit/0a1036eef62f13c9609362874c5b88434d1e9300) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Adds a new `createCodegenDir()` function to the `astro:config:setup` hook in the Integrations API

  In 4.14, we introduced the `injectTypes` utility on the `astro:config:done` hook. It can create `.d.ts` files and make their types available to user's projects automatically. Under the hood, it creates a file in `<root>/.astro/integrations/<normalized_integration_name>`.

  While the `.astro` directory has always been the preferred place to write code generated files, it has also been prone to mistakes. For example, you can write a `.astro/types.d.ts` file, breaking Astro types. Or you can create a file that overrides a file created by another integration.

  In this release, `<root>/.astro/integrations/<normalized_integration_name>` can now be retrieved in the `astro:config:setup` hook by calling `createCodegenDir()`. It allows you to have a dedicated folder, avoiding conflicts with another integration or Astro itself. This directory is created by calling this function so it's safe to write files to it directly:

  ```js
  import { writeFileSync } from 'node:fs';

  const integration = {
    name: 'my-integration',
    hooks: {
      'astro:config:setup': ({ createCodegenDir }) => {
        const codegenDir = createCodegenDir();
        writeFileSync(new URL('cache.json', codegenDir), '{}', 'utf-8');
      },
    },
  };
  ```

- [#12081](https://github.com/withastro/astro/pull/12081) [`8679954`](https://github.com/withastro/astro/commit/8679954bf647529e0f2134053866fc507e64c5e3) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Removes the experimental `contentCollectionsCache` introduced in `3.5.0`.

  Astro Content Layer API independently solves some of the caching and performance issues with legacy content collections that this strategy attempted to address. This feature has been replaced with continued work on improvements to the content layer. If you were using this experimental feature, you must now remove the flag from your Astro config as it no longer exists:

  ```diff
  export default defineConfig({
      experimental: {
  -        contentCollectionsCache: true
      }
  })
  ```

  The `cacheManifest` boolean argument is no longer passed to the `astro:build:done` integration hook:

  ```diff
  const integration = {
      name: "my-integration",
      hooks: {
          "astro:build:done": ({
  -            cacheManifest,
              logger
          }) => {}
      }
  }
  ```

  When using the `image()` schema helper, previously paths with an initial slash were treated as public URLs. This was to match the behavior of markdown images. However this is a change from before, where paths with an initial slash were treated as project-relative. This change restores the previous behavior, so that paths with an initial slash are treated as project-relative.

### Major Changes

- [#11982](https://github.com/withastro/astro/pull/11982) [`d84e444`](https://github.com/withastro/astro/commit/d84e444fd3496c1f787b3fcee2929c92bc74e0cd) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adds a default exclude and include value to the tsconfig presets. `{projectDir}/dist` is now excluded by default, and `{projectDir}/.astro/types.d.ts` and `{projectDir}/**/*` are included by default.

  Both of these options can be overridden by setting your own values to the corresponding settings in your `tsconfig.json` file.

- [#11987](https://github.com/withastro/astro/pull/11987) [`bf90a53`](https://github.com/withastro/astro/commit/bf90a5343f9cd1bb46f30e4b331e7ae675f5e720) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - The `locals` object can no longer be overridden

  Middleware, API endpoints, and pages can no longer override the `locals` object in its entirety. You can still append values onto the object, but you can not replace the entire object and delete its existing values.

  If you were previously overwriting like so:

  ```js
  ctx.locals = {
    one: 1,
    two: 2,
  };
  ```

  This can be changed to an assignment on the existing object instead:

  ```js
  Object.assign(ctx.locals, {
    one: 1,
    two: 2,
  });
  ```

### Minor Changes

- [#11980](https://github.com/withastro/astro/pull/11980) [`a604a0c`](https://github.com/withastro/astro/commit/a604a0ca9e0cdead01610b603d3b4c37ab010efc) Thanks [@matthewp](https://github.com/matthewp)! - ViewTransitions component renamed to ClientRouter

  The `<ViewTransitions />` component has been renamed to `<ClientRouter />`. There are no other changes than the name. The old name will continue to work in Astro 5.x, but will be removed in 6.0.

  This change was done to clarify the role of the component within Astro's View Transitions support. Astro supports View Transitions APIs in a few different ways, and renaming the component makes it more clear that the features you get from the ClientRouter component are slightly different from what you get using the native CSS-based MPA router.

  We still intend to maintain the ClientRouter as before, and it's still important for use-cases that the native support doesn't cover, such as persisting state between pages.

### Patch Changes

- [#11987](https://github.com/withastro/astro/pull/11987) [`bf90a53`](https://github.com/withastro/astro/commit/bf90a5343f9cd1bb46f30e4b331e7ae675f5e720) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - `render()` signature now takes `renderOptions` as 2nd argument

  The signature for `app.render()` has changed, and the second argument is now an options object called `renderOptions` with more options for customizing rendering.

  The `renderOptions` are:
  - `addCookieHeader`: Determines whether Astro will set the `Set-Cookie` header, otherwise the adapter is expected to do so itself.
  - `clientAddress`: The client IP address used to set `Astro.clientAddress`.
  - `locals`: An object of locals that's set to `Astro.locals`.
  - `routeData`: An object specifying the route to use.

### Major Changes

- [#11864](https://github.com/withastro/astro/pull/11864) [`ee38b3a`](https://github.com/withastro/astro/commit/ee38b3a94697fe883ce8300eff9f001470b8adb6) Thanks [@ematipico](https://github.com/ematipico)! - ### [changed]: `entryPoint` type inside the hook `astro:build:ssr`
  In Astro v4.x, the `entryPoint` type was `RouteData`.

  Astro v5.0 the `entryPoint` type is `IntegrationRouteData`, which contains a subset of the `RouteData` type. The fields `isIndex` and `fallbackRoutes` were removed.

  #### What should I do?

  Update your adapter to change the type of `entryPoint` from `RouteData` to `IntegrationRouteData`.

  ```diff
  -import type {RouteData} from 'astro';
  +import type {IntegrationRouteData} from "astro"

  -function useRoute(route: RouteData) {
  +function useRoute(route: IntegrationRouteData) {

  }
  ```

This can be useful in niche situations where the default route `/_image` conflicts with an existing route or your local server setup.

  ```js
  import { defineConfig } from 'astro/config';

  defineConfig({
    image: {
      endpoint: {
        route: '/image',
        entrypoint: './src/image_endpoint.ts',
      },
    },

  Now, relating to assets, only a single `sharpImageService` property is available, determining if the adapter is compatible with the built-in sharp image service.

- [#11864](https://github.com/withastro/astro/pull/11864) [`ee38b3a`](https://github.com/withastro/astro/commit/ee38b3a94697fe883ce8300eff9f001470b8adb6) Thanks [@ematipico](https://github.com/ematipico)! - ### [changed]: `routes` type inside the hook `astro:build:done`
  In Astro v4.x, the `routes` type was `RouteData`.

  Astro v5.0 the `routes` type is `IntegrationRouteData`, which contains a subset of the `RouteData` type. The fields `isIndex` and `fallbackRoutes` were removed.

  #### What should I do?

  Update your adapter to change the type of `routes` from `RouteData` to `IntegrationRouteData`.

  ```diff
  -import type {RouteData} from 'astro';
  +import type {IntegrationRouteData} from "astro"

  -function useRoute(route: RouteData) {
  +function useRoute(route: IntegrationRouteData) {

  }
  ```

- [#11864](https://github.com/withastro/astro/pull/11864) [`ee38b3a`](https://github.com/withastro/astro/commit/ee38b3a94697fe883ce8300eff9f001470b8adb6) Thanks [@ematipico](https://github.com/ematipico)! - ### [changed]: `RouteData.distURL` is now an array
  In Astro v4.x, `RouteData.distURL` was `undefined` or a `URL`

  Astro v5.0, `RouteData.distURL` is `undefined` or an array of `URL`. This was a bug, because a route can generate multiple files on disk, especially when using dynamic routes such as `[slug]` or `[...slug]`.

  #### What should I do?

  Update your code to handle `RouteData.distURL` as an array.

  ```diff
  if (route.distURL) {
  -  if (route.distURL.endsWith('index.html')) {
  -    // do something
  -  }
  +  for (const url of route.distURL) {
  +    if (url.endsWith('index.html')) {
  +      // do something
  +    }
  +  }
  }
  ```

### Minor Changes

- [#11806](https://github.com/withastro/astro/pull/11806) [`f7f2338`](https://github.com/withastro/astro/commit/f7f2338c2b96975001b5c782f458710e9cc46d74) Thanks [@Princesseuh](https://github.com/Princesseuh)! - The value of the different properties on `supportedAstroFeatures` for adapters can now be objects, with a `support` and `message` properties. The content of the `message` property will be shown in the Astro CLI when the adapter is not compatible with the feature, allowing one to give a better informational message to the user.

  This is notably useful with the new `limited` value, to explain to the user why support is limited.

- [#11955](https://github.com/withastro/astro/pull/11955) [`d813262`](https://github.com/withastro/astro/commit/d8132626b05f150341c0628d6078fdd86b89aaed) Thanks [@matthewp](https://github.com/matthewp)! - [Server Islands](https://astro.build/blog/future-of-astro-server-islands/) introduced behind an experimental flag in [v4.12.0](https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#4120) is no longer experimental and is available for general use.

  Server islands are Astro's solution for highly cacheable pages of mixed static and dynamic content. They allow you to specify components that should run on the server, allowing the rest of the page to be more aggressively cached, or even generated statically.

  Turn any `.astro` component into a server island by adding the `server:defer` directive and optionally, fallback placeholder content. It will be rendered dynamically at runtime outside the context of the rest of the page, allowing you to add longer cache headers for the pages, or even prerender them.

  ```astro
  ---
  import Avatar from '../components/Avatar.astro';
  import GenericUser from '../components/GenericUser.astro';
  ---

  <header>
    <h1>Page Title</h1>
    <div class="header-right">
      <Avatar server:defer>
        <GenericUser slot="fallback" />
      </Avatar>
    </div>
  </header>
  ```

  If you were previously using this feature, please remove the experimental flag from your Astro config:

  ```diff
  import { defineConfig } from 'astro/config';

  export default defineConfig({
    experimental {
  -    serverIslands: true,
    },
  });
  ```

  If you have been waiting for stabilization before using server islands, you can now do so.

  Please see the [server island documentation](https://docs.astro.build/en/guides/server-islands/) for more about this feature.

This is useful for adapters that support a feature, but not in all cases or with all options.

  When importing `astro/config`, types from `astro/client` will be made automatically available to your project. If your project `tsconfig.json` changes how references behave, you'll still have access to these types after running `astro sync`.

  It is no longer necessary to specify `output: 'hybrid'` in your Astro config to use server-rendered pages. The new `output: 'static'` has this capability included. Astro will now automatically provide the ability to opt out of prerendering in your static site with no change to your `output` configuration required. Any page route or endpoint can include `export const prerender = false` to be server-rendered, while the rest of your site is statically-generated.

  If your project used hybrid rendering, you must now remove the `output: 'hybrid'` option from your Astro config as it no longer exists. However, no other changes to your project are required, and you should have no breaking changes. The previous `'hybrid'` behavior is now the default, under a new name `'static'`.

  If you were using the `output: 'static'` (default) option, you can continue to use it as before. By default, all of your pages will continue to be prerendered and you will have a completely static site. You should have no breaking changes to your project.

  ```diff
  import { defineConfig } from "astro/config";

  export default defineConfig({
  -  output: 'hybrid',
  });
  ```

  An adapter is still required to deploy an Astro project with any server-rendered pages. Failure to include an adapter will result in a warning in development and an error at build time.

### Minor Changes

- [#11941](https://github.com/withastro/astro/pull/11941) [`b6a5f39`](https://github.com/withastro/astro/commit/b6a5f39846581d0e9cfd7ae6f056c8d1209f71bd) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adapters can now specify the build output type they're intended for using the `adapterFeatures.buildOutput` property. This property can be used to always generate a server output, even if the project doesn't have any server-rendered pages.

  ```ts
  {
    'astro:config:done': ({ setAdapter, config }) => {
      setAdapter({
        name: 'my-adapter',
        adapterFeatures: {
          buildOutput: 'server',
        },
      });
    },
  }
  ```

  If your adapter specifies `buildOutput: 'static'`, and the user's project contains server-rendered pages, Astro will warn in development and error at build time. Note that a hybrid output, containing both static and server-rendered pages, is considered to be a `server` output, as a server is required to serve the server-rendered pages.

- [#11941](https://github.com/withastro/astro/pull/11941) [`b6a5f39`](https://github.com/withastro/astro/commit/b6a5f39846581d0e9cfd7ae6f056c8d1209f71bd) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Adds a new `buildOutput` property to the `astro:config:done` hook returning the build output type.

  This can be used to know if the user's project will be built as a static site (HTML files), or a server-rendered site (whose exact output depends on the adapter).

### Patch Changes

- [#11960](https://github.com/withastro/astro/pull/11960) [`4410130`](https://github.com/withastro/astro/commit/4410130df722eae494caaa46b17c8eeb6223f160) Thanks [@ascorbic](https://github.com/ascorbic)! - Fixes an issue where the refresh context data was not passed correctly to content layer loaders

- [#11952](https://github.com/withastro/astro/pull/11952) [`50a0146`](https://github.com/withastro/astro/commit/50a0146e9aff78a245914125f34719cfb32c585f) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds support for array patterns in the built-in `glob()` content collections loader

  The glob loader can now accept an array of multiple patterns as well as string patterns. This allows you to more easily combine multiple patterns into a single collection, and also means you can use negative matches to exclude files from the collection.

  ```ts
  const probes = defineCollection({
    // Load all markdown files in the space-probes directory, except for those that start with "voyager-"
    loader: glob({ pattern: ['*.md', '!voyager-*'], base: 'src/data/space-probes' }),
    schema: z.object({
      name: z.string(),
      type: z.enum(['Space Probe', 'Mars Rover', 'Comet Lander']),
      launch_date: z.date(),
      status: z.enum(['Active', 'Inactive', 'Decommissioned']),
      destination: z.string(),
      operator: z.string(),
      notable_discoveries: z.array(z.string()),
    }),
  });
  ```

### Major Changes

- [#11916](https://github.com/withastro/astro/pull/11916) [`46ea29f`](https://github.com/withastro/astro/commit/46ea29f91df83ea638ecbc544ce99375538636d4) Thanks [@bluwy](https://github.com/bluwy)! - Updates how the `build.client` and `build.server` option values get resolved to match existing documentation. With this fix, the option values will now correctly resolve relative to the `outDir` option. So if `outDir` is set to `./dist/nested/`, then by default:
  - `build.client` will resolve to `<root>/dist/nested/client/`
  - `build.server` will resolve to `<root>/dist/nested/server/`

  Previously the values were incorrectly resolved:
  - `build.client` was resolved to `<root>/dist/nested/dist/client/`
  - `build.server` was resolved to `<root>/dist/nested/dist/server/`

  If you were relying on the previous build paths, make sure that your project code is updated to the new build paths.

### Minor Changes

- [#11875](https://github.com/withastro/astro/pull/11875) [`a8a3d2c`](https://github.com/withastro/astro/commit/a8a3d2cde813d891dd9c63f07f91ce4e77d4f93b) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Adds a new property `isPrerendered` to the globals `Astro` and `APIContext` . This boolean value represents whether or not the current page is prerendered:

  ```astro
  ---
  // src/pages/index.astro

  export const prerender = true;
  ---
  ```

  ```js
  // src/middleware.js

  export const onRequest = (ctx, next) => {
    console.log(ctx.isPrerendered); // it will log true
    return next();
  };
  ```

### Patch Changes

- [#11927](https://github.com/withastro/astro/pull/11927) [`5b4e3ab`](https://github.com/withastro/astro/commit/5b4e3abbb152146b71c1af05d33c96211000b2a6) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Updates the `env` configuration reference docs to include a full API reference for `envField`.

## 5.0.0-alpha.4

### Major Changes

- [#11859](https://github.com/withastro/astro/pull/11859) [`3804711`](https://github.com/withastro/astro/commit/38047119ff454e80cddd115bff53e33b32cd9930) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - Changes the default `tsconfig.json` with better defaults, and makes `src/env.d.ts` optional

  Astro's default `tsconfig.json` in starter examples has been updated to include generated types and exclude your build output. This means that `src/env.d.ts` is only necessary if you have added custom type declarations or if you're not using a `tsconfig.json` file.

  Additionally, running `astro sync` no longer creates, nor updates, `src/env.d.ts` as it is not required for type-checking standard Astro projects.

  To update your project to Astro's recommended TypeScript settings, please add the following `include` and `exclude` properties to `tsconfig.json`:

  ```diff
  {
      "extends": "astro/tsconfigs/base",
  +    "include": [".astro/types.d.ts", "**/*"],
  +    "exclude": ["dist"]
  }
  ```

### Minor Changes

- [#11911](https://github.com/withastro/astro/pull/11911) [`c3dce83`](https://github.com/withastro/astro/commit/c3dce8363be22121a567df22df2ec566a3ebda17) Thanks [@ascorbic](https://github.com/ascorbic)! - The Content Layer API introduced behind a flag in [4.14.0](https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#4140) is now stable and ready for use in Astro v5.0.

  The new Content Layer API builds upon content collections, taking them beyond local files in `src/content/` and allowing you to fetch content from anywhere, including remote APIs. These new collections work alongside your existing content collections, and you can migrate them to the new API at your own pace. There are significant improvements to performance with large collections of local files. For more details, see [the Content Layer RFC](https://github.com/withastro/roadmap/blob/content-layer/proposals/0050-content-layer.md).

  If you previously used this feature, you can now remove the `experimental.contentLayer` flag from your Astro config:

  ```diff
  // astro.config.mjs
  import { defineConfig } from 'astro'

  export default defineConfig({
  -  experimental: {
  -    contentLayer: true
  -  }
  })
  ```

  ### Loading your content

  The core of the new Content Layer API is the loader, a function that fetches content from a source and caches it in a local data store. Astro 4.14 ships with built-in `glob()` and `file()` loaders to handle your local Markdown, MDX, Markdoc, and JSON files:

  ```ts {3,7}
  // src/content/config.ts
  import { defineCollection, z } from 'astro:content';
  import { glob } from 'astro/loaders';

  const blog = defineCollection({
    // The ID is a slug generated from the path of the file relative to `base`
    loader: glob({ pattern: '**/*.md', base: './src/data/blog' }),
    schema: z.object({
      title: z.string(),
      description: z.string(),
      publishDate: z.coerce.date(),
    }),
  });

  export const collections = { blog };
  ```

  You can then query using the existing content collections functions, and use a simplified `render()` function to display your content:

  ```astro
  ---
  import { getEntry, render } from 'astro:content';

  const post = await getEntry('blog', Astro.params.slug);

  const { Content } = await render(entry);
  ---

  <Content />
  ```

  ### Creating a loader

  You're not restricted to the built-in loaders – we hope you'll try building your own. You can fetch content from anywhere and return an array of entries:

  ```ts
  // src/content/config.ts
  const countries = defineCollection({
    loader: async () => {
      const response = await fetch('https://restcountries.com/v3.1/all');
      const data = await response.json();
      // Must return an array of entries with an id property,
      // or an object with IDs as keys and entries as values
      return data.map((country) => ({
        id: country.cca3,
        ...country,
      }));
    },
    // optionally add a schema to validate the data and make it type-safe for users
    // schema: z.object...
  });

  export const collections = { countries };
  ```

  For more advanced loading logic, you can define an object loader. This allows incremental updates and conditional loading, and gives full access to the data store. It also allows a loader to define its own schema, including generating it dynamically based on the source API. See the [the Content Layer API RFC](https://github.com/withastro/roadmap/blob/content-layer/proposals/0050-content-layer.md#loaders) for more details.

  ### Sharing your loaders

  Loaders are better when they're shared. You can create a package that exports a loader and publish it to npm, and then anyone can use it on their site. We're excited to see what the community comes up with! To get started, [take a look at some examples](https://github.com/ascorbic/astro-loaders/). Here's how to load content using an RSS/Atom feed loader:

  ```ts
  // src/content/config.ts
  import { defineCollection } from 'astro:content';
  import { feedLoader } from '@ascorbic/feed-loader';

  const podcasts = defineCollection({
    loader: feedLoader({
      url: 'https://feeds.99percentinvisible.org/99percentinvisible',
    }),
  });

  export const collections = { podcasts };
  ```

  The `ScopedDataStore` interface (which was previously internal) is renamed to `DataStore`, to reflect the fact that it's the only public API for the data store.

## 5.0.0-alpha.3

### Major Changes

- [#11861](https://github.com/withastro/astro/pull/11861) [`3ab3b4e`](https://github.com/withastro/astro/commit/3ab3b4efbcdd2aabea5f949deedf51a5acefae59) Thanks [@bluwy](https://github.com/bluwy)! - Cleans up Astro-specific metadata attached to `vfile.data` in Remark and Rehype plugins. Previously, the metadata was attached in different locations with inconsistent names. The metadata is now renamed as below:
  - `vfile.data.__astroHeadings` -> `vfile.data.astro.headings`
  - `vfile.data.imagePaths` -> `vfile.data.astro.imagePaths`

  The types of `imagePaths` has also been updated from `Set<string>` to `string[]`. The `vfile.data.astro.frontmatter` metadata is left unchanged.

  While we don't consider these APIs public, they can be accessed by Remark and Rehype plugins that want to re-use Astro's metadata. If you are using these APIs, make sure to access them in the new locations.

- [#11825](https://github.com/withastro/astro/pull/11825) [`560ef15`](https://github.com/withastro/astro/commit/560ef15ad23bd137b56ef1048eb2df548b99fdce) Thanks [@bluwy](https://github.com/bluwy)! - Updates internal Shiki rehype plugin to highlight code blocks as hast (using Shiki's `codeToHast()` API). This allows a more direct Markdown and MDX processing, and improves the performance when building the project, but may cause issues with existing Shiki transformers.

  If you are using Shiki transformers passed to `markdown.shikiConfig.transformers`, you must make sure they do not use the `postprocess` hook as it no longer runs on code blocks in `.md` and `.mdx` files. (See [the Shiki documentation on transformer hooks](https://shiki.style/guide/transformers#transformer-hooks) for more information).

  Code blocks in `.mdoc` files and `<Code />` component do not use the internal Shiki rehype plugin and are unaffected.

- [#11819](https://github.com/withastro/astro/pull/11819) [`2bdde80`](https://github.com/withastro/astro/commit/2bdde80cd3107d875e2d77e6e9621001e0e8b38a) Thanks [@bluwy](https://github.com/bluwy)! - Updates the Astro config loading flow to ignore processing locally-linked dependencies with Vite (e.g. `npm link`, in a monorepo, etc). Instead, they will be normally imported by the Node.js runtime the same way as other dependencies from `node_modules`.

  Previously, Astro would process locally-linked dependencies which were able to use Vite features like TypeScript when imported by the Astro config file.

  However, this caused confusion as integration authors may test against a package that worked locally, but not when published. This method also restricts using CJS-only dependencies because Vite requires the code to be ESM. Therefore, Astro's behaviour is now changed to ignore processing any type of dependencies by Vite.

  In most cases, make sure your locally-linked dependencies are built to JS before running the Astro project, and the config loading should work as before.

### Patch Changes

- [#11878](https://github.com/withastro/astro/pull/11878) [`334948c`](https://github.com/withastro/astro/commit/334948ced29ed9ab03992f2174547bb9ee3a20c0) Thanks [@ascorbic](https://github.com/ascorbic)! - Adds a new function `refreshContent` to the `astro:server:setup` hook that allows integrations to refresh the content layer. This can be used, for example, to register a webhook endpoint during dev, or to open a socket to a CMS to listen for changes.

  By default, `refreshContent` will refresh all collections. You can optionally pass a `loaders` property, which is an array of loader names. If provided, only collections that use those loaders will be refreshed. For example, A CMS integration could use this property to only refresh its own collections.

  You can also pass a `context` object to the loaders. This can be used to pass arbitrary data, such as the webhook body, or an event from the websocket.

  ```ts
   {
      name: 'my-integration',
      hooks: {
          'astro:server:setup': async ({ server, refreshContent }) => {
              server.middlewares.use('/_refresh', async (req, res) => {
                  if(req.method !== 'POST') {
                    res.statusCode = 405
                    res.end('Method Not Allowed');
                    return
                  }
                  let body = '';
                  req.on('data', chunk => {
                      body += chunk.toString();
                  });
                  req.on('end', async () => {
                      try {
                          const webhookBody = JSON.parse(body);
                          await refreshContent({
                            context: { webhookBody },
                            loaders: ['my-loader']
                          });
                          res.writeHead(200, { 'Content-Type': 'application/json' });
                          res.end(JSON.stringify({ message: 'Content refreshed successfully' }));
                      } catch (error) {
                          res.writeHead(500, { 'Content-Type': 'application/json' });
                          res.end(JSON.stringify({ error: 'Failed to refresh content: ' + error.message }));
                      }
                  });
              });

### Major Changes

- [#11826](https://github.com/withastro/astro/pull/11826) [`7315050`](https://github.com/withastro/astro/commit/7315050fc1192fa72ae92aef92b920f63b46118f) Thanks [@matthewp](https://github.com/matthewp)! - Deprecate Astro.glob

  The `Astro.glob` function has been deprecated in favor of Content Collections and `import.meta.glob`.
  - If you want to query for markdown and MDX in your project, use Content Collections.
  - If you want to query source files in your project, use `import.meta.glob`(https://vitejs.dev/guide/features.html#glob-import).

  Also consider using glob packages from npm, like [fast-glob](https://www.npmjs.com/package/fast-glob), especially if statically generating your site, as it is faster for most use-cases.

  The easiest path is to migrate to `import.meta.glob` like so:

  ```diff
  - const posts = Astro.glob('./posts/*.md');
  + const posts = Object.values(import.meta.glob('./posts/*.md', { eager: true }));
  ```

- [#11827](https://github.com/withastro/astro/pull/11827) [`a83e362`](https://github.com/withastro/astro/commit/a83e362ee41174501a433c210a24696784d7368f) Thanks [@matthewp](https://github.com/matthewp)! - Prevent usage of `astro:content` in the client

  Usage of `astro:content` in the client has always been discouraged because it leads to all of your content winding up in your client bundle, and can possibly leaks secrets.

  This formally makes doing so impossible, adding to the previous warning with errors.

  In the future Astro might add APIs for client-usage based on needs.

- [#11253](https://github.com/withastro/astro/pull/11253) [`4e5cc5a`](https://github.com/withastro/astro/commit/4e5cc5aadd7d864bc5194ee67dc2ea74dbe80473) Thanks [@kevinzunigacuellar](https://github.com/kevinzunigacuellar)! - Changes the data returned for `page.url.current`, `page.url.next`, `page.url.prev`, `page.url.first` and `page.url.last` to include the value set for `base` in your Astro config.

  Previously, you had to manually prepend your configured value for `base` to the URL path. Now, Astro automatically includes your `base` value in `next` and `prev` URLs.

  If you are using the `paginate()` function for "previous" and "next" URLs, remove any existing `base` value as it is now added for you:

  ```diff
  ---
  export async function getStaticPaths({ paginate }) {

### Minor Changes

- [#11698](https://github.com/withastro/astro/pull/11698) [`05139ef`](https://github.com/withastro/astro/commit/05139ef8b46de96539cc1d08148489eaf3cfd837) Thanks [@ematipico](https://github.com/ematipico)! - Adds a new property to the globals `Astro` and `APIContext` called `routePattern`. The `routePattern` represents the current route (component)
  that is being rendered by Astro. It's usually a path pattern will look like this: `blog/[slug]`:

  ```asto
  ---
  // src/pages/blog/[slug].astro
  const route = Astro.routePattern;
  console.log(route); // it will log "blog/[slug]"
  ---
  ```

  ```js
  // src/pages/index.js

  export const GET = (ctx) => {
    console.log(ctx.routePattern); // it will log src/pages/index.js
    return new Response.json({ loreum: 'ipsum' });
  };
  ```

### Patch Changes

- [#11791](https://github.com/withastro/astro/pull/11791) [`9393243`](https://github.com/withastro/astro/commit/93932432e7239a1d31c68ea916945302286268e9) Thanks [@bluwy](https://github.com/bluwy)! - Updates Astro's default `<script>` rendering strategy and removes the `experimental.directRenderScript` option as this is now the default behavior: scripts are always rendered directly. This new strategy prevents scripts from being executed in pages where they are not used.

  Scripts will directly render as declared in Astro files (including existing features like TypeScript, importing `node_modules`, and deduplicating scripts). You can also now conditionally render scripts in your Astro file.

  However, this means scripts are no longer hoisted to the `<head>`, multiple scripts on a page are no longer bundled together, and the `<script>` tag may interfere with the CSS styling.

  As this is a potentially breaking change to your script behavior, please review your `<script>` tags and ensure that they behave as expected.

### Major Changes

- [#11798](https://github.com/withastro/astro/pull/11798) [`e9e2139`](https://github.com/withastro/astro/commit/e9e2139bf788893566f5a3fe58daf1d24076f018) Thanks [@matthewp](https://github.com/matthewp)! - Unflag globalRoutePriority

  The previously [experimental feature `globalRoutePriority`](https://docs.astro.build/en/reference/configuration-reference/#experimentalglobalroutepriority) is now the default in Astro 5.

  This was a refactoring of route prioritization in Astro, making it so that injected routes, file-based routes, and redirects are all prioritized using the same logic. This feature has been enabled for all Starlight projects since it was added and should not affect most users.

- [#11679](https://github.com/withastro/astro/pull/11679) [`ea71b90`](https://github.com/withastro/astro/commit/ea71b90c9c08ddd1d3397c78e2e273fb799f7dbd) Thanks [@florian-lefebvre](https://github.com/florian-lefebvre)! - The [`astro:env` feature introduced behind a flag](https://docs.astro.build/en/reference/configuration-reference/#experimentalglobalroutepriority) in [v4.10.0](https://github.com/withastro/astro/blob/main/packages/astro/CHANGELOG.md#x4100) is no longer experimental and is available for general use. If you have been waiting for stabilization before using `astro:env`, you can now do so.

  This feature lets you configure a type-safe schema for your environment variables, and indicate whether they should be available on the server or the client.

  To configure a schema, add the `env` option to your Astro config and define your client and server variables. If you were previously using this feature, please remove the experimental flag from your Astro config and move your entire `env` configuration unchanged to a top-level option.

  ```js
  import { defineConfig, envField } from 'astro/config';

  export default defineConfig({
    env: {
      schema: {
        API_URL: envField.string({ context: 'client', access: 'public', optional: true }),
        PORT: envField.number({ context: 'server', access: 'public', default: 4321 }),
        API_SECRET: envField.string({ context: 'server', access: 'secret' }),
      },
    },
  });
  ```

  You can import and use your defined variables from the appropriate `/client` or `/server` module:

  ```astro
  ---
  import { API_URL } from 'astro:env/client';
  import { API_SECRET_TOKEN } from 'astro:env/server';

  const data = await fetch(`${API_URL}/users`, {
    method: 'GET',
    headers: {
      'Content-Type': 'application/json',
      Authorization: `Bearer ${API_SECRET_TOKEN}`,
    },
  });
  ---

  <script>
    import { API_URL } from 'astro:env/client';

    fetch(`${API_URL}/ping`);
  </script>
  ```

- [#11788](https://github.com/withastro/astro/pull/11788) [`7c0ccfc`](https://github.com/withastro/astro/commit/7c0ccfc26947b178584e3476584bcaa490c6ba86) Thanks [@ematipico](https://github.com/ematipico)! - Updates the default value of `security.checkOrigin` to `true`, which enables Cross-Site Request Forgery (CSRF) protection by default for pages rendered on demand.

  If you had previously configured `security.checkOrigin: true`, you no longer need this set in your Astro config. This is now the default and it is safe to remove.

  To disable this behavior and opt out of automatically checking that the “origin” header matches the URL sent by each request, you must explicitly set `security.checkOrigin: false`:

  ```diff
  export default defineConfig({
  +  security: {
  +    checkOrigin: false
  +  }
  })
  ```

- [#11741](https://github.com/withastro/astro/pull/11741) [`6617491`](https://github.com/withastro/astro/commit/6617491c3bc2bde87f7867d7dec2580781852cfc) Thanks [@bluwy](https://github.com/bluwy)! - Removes internal JSX handling and moves the responsibility to the `@astrojs/mdx` package directly. The following exports are also now removed:
  - `astro/jsx/babel.js`
  - `astro/jsx/component.js`
  - `astro/jsx/index.js`
  - `astro/jsx/renderer.js`
  - `astro/jsx/server.js`
  - `astro/jsx/transform-options.js`

  If your project includes `.mdx` files, you must upgrade `@astrojs/mdx` to the latest version so that it doesn't rely on these entrypoints to handle your JSX.

- [#11782](https://github.com/withastro/astro/pull/11782) [`9a2aaa0`](https://github.com/withastro/astro/commit/9a2aaa01ea427df3844bce8595207809a8d2cb94) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Makes the `compiledContent` property of Markdown content an async function, this change should fix underlying issues where sometimes when using a custom image service and images inside Markdown, Node would exit suddenly without any error message.

  ```diff
  ---
  import * as myPost from "../post.md";

  - const content = myPost.compiledContent();
  + const content = await myPost.compiledContent();
  ---

  <Fragment set:html={content} />
  ```

- [#11770](https://github.com/withastro/astro/pull/11770) [`cfa6a47`](https://github.com/withastro/astro/commit/cfa6a47ac7a541f99fdad46a68d0cca6e5816cd5) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Removed support for the Squoosh image service. As the underlying library `libsquoosh` is no longer maintained, and the image service sees very little usage we have decided to remove it from Astro.

  Our recommendation is to use the base Sharp image service, which is more powerful, faster, and more actively maintained.

  ```diff
  - import { squooshImageService } from "astro/config";
  import { defineConfig } from "astro/config";

  export default defineConfig({
  -  image: {
  -    service: squooshImageService()
  -  }
  });
  ```

  If you are using this service, and cannot migrate to the base Sharp image service, a third-party extraction of the previous service is available here: https://github.com/Princesseuh/astro-image-service-squoosh

### Major Changes

- [#10742](https://github.com/withastro/astro/pull/10742) [`b6fbdaa`](https://github.com/withastro/astro/commit/b6fbdaa94a9ecec706a99e1938fbf5cd028c72e0) Thanks [@ematipico](https://github.com/ematipico)! - The lowest version of Node supported by Astro is now Node v18.17.1 and higher.

- [#11715](https://github.com/withastro/astro/pull/11715) [`d74617c`](https://github.com/withastro/astro/commit/d74617cbd3278feba05909ec83db2d73d57a153e) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Refactor the exported types from the `astro` module. There should normally be no breaking changes, but if you relied on some previously deprecated types, these might now have been fully removed.

  In most cases, updating your code to move away from previously deprecated APIs in previous versions of Astro should be enough to fix any issues.

- [#11660](https://github.com/withastro/astro/pull/11660) [`e90f559`](https://github.com/withastro/astro/commit/e90f5593d23043579611452a84b9e18ad2407ef9) Thanks [@bluwy](https://github.com/bluwy)! - Fixes attribute rendering for non-[boolean HTML attributes](https://developer.mozilla.org/en-US/docs/Glossary/Boolean/HTML) with boolean values to match proper attribute handling in browsers.

  Previously, non-boolean attributes may not have included their values when rendered to HTML. In Astro v5.0, the values are now explicitly rendered as `="true"` or `="false"`

  In the following `.astro` examples, only `allowfullscreen` is a boolean attribute:

  ```astro
  <!-- src/pages/index.astro --><!-- `allowfullscreen` is a boolean attribute -->
  <p allowfullscreen={true}></p>
  <p allowfullscreen={false}></p>

  <!-- `inherit` is *not* a boolean attribute -->
  <p inherit={true}></p>
  <p inherit={false}></p>

  <!-- `data-*` attributes are not boolean attributes -->
  <p data-light={true}></p>
  <p data-light={false}></p>
  ```

  Astro v5.0 now preserves the full data attribute with its value when rendering the HTML of non-boolean attributes:

  ```diff
    <p allowfullscreen></p>
    <p></p>

    <p inherit="true"></p>
  - <p inherit></p>
  + <p inherit="false"></p>

  - <p data-light></p>
  + <p data-light="true"></p>
  - <p></p>
  + <p data-light="false"></p>
  ```

  If you rely on attribute values, for example to locate elements or to conditionally render, update your code to match the new non-boolean attribute values:

  ```diff
  - el.getAttribute('inherit') === ''
  + el.getAttribute('inherit') === 'false'

  - el.hasAttribute('data-light')
  + el.dataset.light === 'true'
  ```

- [#11714](https://github.com/withastro/astro/pull/11714) [`8a53517`](https://github.com/withastro/astro/commit/8a5351737d6a14fc55f1dafad8f3b04079e81af6) Thanks [@matthewp](https://github.com/matthewp)! - Remove support for functionPerRoute

  This change removes support for the `functionPerRoute` option both in Astro and `@astrojs/vercel`.

  This option made it so that each route got built as separate entrypoints so that they could be loaded as separate functions. The hope was that by doing this it would decrease the size of each function. However in practice routes use most of the same code, and increases in function size limitations made the potential upsides less important.

  Additionally there are downsides to functionPerRoute, such as hitting limits on the number of functions per project. The feature also never worked with some Astro features like i18n domains and request rewriting.

  Given this, the feature has been removed from Astro.
