-In the production branch of `server.js` we need to read and pass the manifest to the `render` function exported by `src/entry-server.js`. This would provide us with enough information to render preload directives for files used by async routes!

 ## Pre-Rendering / SSG
 
-If the routes and the data needed for certain routes are known ahead of time, we can pre-render these routes into static HTML using the same logic as production SSR. This can also be considered a form of Static-Site Generation (SSG). See [demo pre-render script](https://github.com/vitejs/vite/blob/main/playground/ssr-vue/prerender.js) for working example.
