Biome CLI v2.4.12

2.4.12

Patch Changes

• #9376 9701a33 Thanks @​dyc3! - Added the nursery/noIdenticalTestTitle lint rule. This rule disallows using the same title for two describe blocks or two test cases at the same nesting level.

  describe("foo", () => {});
  describe("foo", () => {
    // invalid: same title as previous describe block
    test("baz", () => {});
    test("baz", () => {}); // invalid: same title as previous test case
  });

• #9889 7ae83f2 Thanks @​dyc3! - Improved the diagnostics for useForOf to better explain the problem, why it matters, and how to fix it.

• #9916 27dd7b1 Thanks @​Jayllyz! - Added a new nursery rule noComponentHookFactories, that disallows defining React components or custom hooks inside other functions.

  For example, the following snippets trigger the rule:

  function createComponent(label) {
    function MyComponent() {
      return <div>{label}</div>;
    }
    return MyComponent;
  }

  function Parent() {
    function Child() {
      return <div />;
    }
    return <Child />;
  }

• #9980 098f1ff Thanks @​ematipico! - Fixed #9941: Biome now emits a warning diagnostic when a file exceed the files.maxSize limit.

• #9942 9956f1d Thanks @​dyc3! - Fixed #9918: useConsistentTestIt no longer panics when applying fixes to chained calls such as test.for([])("x", () => {});.

• #9891 4d9ac51 Thanks @​dyc3! - Improved the noGlobalObjectCalls diagnostic to better explain why calling global objects like Math or JSON is invalid and how to fix it.

• #9902 3f4d103 Thanks @​ematipico! - Fixed #9901: the command lint --write is now idempotent when it's run against HTML-ish files that contains scripts and styles.

• #9891 4d9ac51 Thanks @​dyc3! - Improved the noMultiStr diagnostic to explain why escaped multiline strings are discouraged and what to use instead.

Biome 2.0 migration guide breaking changes from version 1.x

💡 Result:

To migrate from Biome 1.x to 2.0+, follow the official upgrade guide from biomejs.dev. Upgrade steps: 1. Install Biome 2.0.6 or later: npm install --save-dev --save-exact @biomejs/biome@2.0.6 (or equivalent for pnpm/yarn/bun/deno). 2. Run npx @biomejs/biome migrate --write to automatically update your biome.json/biome.jsonc configuration for most breaking changes. Review the output for any manual steps needed. Key breaking changes (biome migrate handles many automatically): - Rome-related features removed: Rename rome.json to biome.json; // rome-ignore to // biome-ignore; ROME_BINARY to BIOME_BINARY; suppression format changed to // biome-ignore lint/: . - --config-path CLI option removed from biome lsp-proxy and biome start (use editor plugins that support workspace/configuration). - Globs/paths: Now resolved from config file location (not working directory); no automatic / prepending; include/ignore merged into includes with new syntax. - linter 'all' option removed (enable rules explicitly). - Style rules: No longer error by default (warn unless configured); some recommended rules changed. - Import organizer: New sorter with different order (e.g., non-node: Node modules not prioritized before others); config moved from organizeImports to assist.actions.source.organizeImports. - Syntax assert unsupported (use with syntax). - Linter behavior: Recommended rules now warn (not error); style group warns by default. - Extensions: Update Zed/VS Code extensions for compatibility. - Other: noUndeclaredVariables ignores TS types; JSON formatter no trailing commas; etc. Biome v2 released June 2025 with type-aware linting. Current version ~2.4.x as of 2026. For full details, see https://biomejs.dev/guides/upgrade-to-biome-v2/. Run biome migrate first when upgrading from 1.x.

Fix biome suppression comments before upgrading to v2.4.12—several use an invalid placeholder format.

The upgrade to v2.4.12 introduces breaking changes in suppression comment syntax. Multiple files contain biome-ignore comments with <explanation> placeholders, which are not valid in v2.4.12:

• src/common/commonTypes.ts:1
• src/config/ConfigScope.spec.ts (lines 124, 152, 183, 223, 835)

These must be rewritten with actual reasons instead of placeholders (e.g., // biome-ignore lint/suspicious/noExplicitAny: intentional use instead of // biome-ignore lint/suspicious/noExplicitAny: <explanation>).

Additionally, the biome.json schema version is at 2.4.11 but the CLI will be 2.4.12. Update the schema reference to 2.4.12 or run biome migrate --write to auto-update both issues.
