Minor Changes

• #​10935 ddd8e49 Thanks @​bluwy! - Exports astro/jsx/rehype.js with utilities to generate an Astro metadata object

• #​10625 698c2d9 Thanks @​goulvenclech! - Adds the ability for multiple pages to use the same component as an entrypoint when building an Astro integration. This change is purely internal, and aligns the build process with the behaviour in the development server.

• #​10906 7bbd664 Thanks @​Princesseuh! - Adds a new radio checkbox component to the dev toolbar UI library (astro-dev-toolbar-radio-checkbox)

• #​10963 61f47a6 Thanks @​delucis! - Adds support for passing an inline Astro configuration object to getViteConfig()

  If you are using getViteConfig() to configure the Vitest test runner, you can now pass a second argument to control how Astro is configured. This makes it possible to configure unit tests with different Astro options when using Vitest’s workspaces feature.

  // vitest.config.ts
  import { getViteConfig } from 'astro/config';
  
  export default getViteConfig(
    /* Vite configuration */
    { test: {} },
    /* Astro configuration */
    {
      site: 'https://example.com',
      trailingSlash: 'never',
    }
  );

• #​10867 47877a7 Thanks @​ematipico! - Adds experimental rewriting in Astro with a new rewrite() function and the middleware next() function.

  The feature is available via an experimental flag in astro.config.mjs:

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

  When enabled, you can use rewrite() to render another page without changing the URL of the browser in Astro pages and endpoints.
