🍿 Minor Changes

• #15460 ee7e53f Thanks @florian-lefebvre! - Updates the Adapter API to allow providing a serverEntrypoint when using entryType: 'self'

  Astro 6 introduced a new powerful yet simple Adapter API for defining custom server entrypoints. You can now call setAdapter() with the entryType: 'self' option and specify your custom serverEntrypoint:

  export function myAdapter() {
    return {
      name: 'my-adapter',
      hooks: {
        'astro:config:done': ({ setAdapter }) => {
          setAdapter({
            name: 'my-adapter',
            entryType: 'self',
            serverEntrypoint: 'my-adapter/server.js',
            supportedAstroFeatures: {
              // ...
            },
          });
        },
      },
    };
  }

  If you need further customization at the Vite level, you can omit serverEntrypoint and instead specify your custom server entrypoint with vite.build.rollupOptions.input.
