v7.0.0

Compare Source

Major Changes

• #​17951 e5b0ac4 Thanks @​hanford! - Migrates the React integration to @vitejs/plugin-react v6, using Oxc for JSX and Fast Refresh. Removes the babel integration option; projects with custom Babel transforms must configure @rolldown/plugin-babel under vite.plugins instead.

  Adds an opt-in compiler option for the Oxc-based React Compiler. Install oxc-transform-react and enable it in your Astro config:

  import react from '@astrojs/react';
  
  export default {
    integrations: [react({ compiler: true })],
  };

  The compiler memoizes client components and hooks. Server rendering is not compiled. The target defaults to the installed React major version; React 17 and 18 projects also need react-compiler-runtime installed. Pass an options object to configure the compiler, for example compiler: { compilationMode: 'annotation' }. The integration's include and exclude options apply, and dependencies and Astro files are excluded.

v6.0.6

Patch Changes

• #​17985 7a6e7f7 Thanks @​astro-factory! - Fixes Vue render-function components failing to build when @astrojs/react is also enabled. React's renderer check no longer crashes on non-React object components, and Vue's check now recognizes defineComponent() components that use a setup function returning a render function.

Major Changes

• #​15819 cafec4e Thanks @​delucis! - Upgrade to Vite v8

Minor Changes

• #​17093 4585fe5 Thanks @​Princesseuh! - Replaces the import entrypoint of getContainerRenderer()

  A new container-renderer entrypoint exporting getContainerRenderer() has been added to the following integrations: React, Preact, Svelte, SolidJS, Vue, and MDX. This prevents bundlers from trying to bundle unrelated exports from the package root when only the Container API is used.

  If you are using the Container API, update your import statements to use the new entrypoint. The following example updates the getContainerRenderer() import for React:

  - import { getContainerRenderer } from '@astrojs/react';
  + import { getContainerRenderer } from '@astrojs/react/container-renderer';

  Importing getContainerRenderer() from the package root still works, but is now deprecated and logs a warning.

Patch Changes

• #​17027 241250b Thanks @​ocavue! - Triggers beta prereleases for packages that are still on alpha

⚖️ Safety Assessment: ⚠️ Needs Manual Migration

🔍 Release Content Analysis

v6.0.0 (Breaking Changes):

• Vite v8 upgrade: @astrojs/react v6 migrated to Vite v8 internally. This is a breaking change in the integration's underlying toolchain.
• New container-renderer entrypoint: getContainerRenderer() can now be imported from @astrojs/react/container-renderer (root import deprecated with a warning, not removed).

v7.0.0 (Breaking Changes):

• babel option removed: The integration dropped the babel config option. @vitejs/plugin-react was upgraded to v6 (Oxc-based) from v5 (Babel-based). Projects using custom Babel transforms must now use @rolldown/plugin-babel under vite.plugins instead.
• New opt-in compiler option: Oxc-based React Compiler support via react({ compiler: true }) — opt-in, not required.
• @vitejs/plugin-react upgraded: 5.2.0 (Babel + Vite 7) → 6.1.2 (Oxc + Vite 8).

🎯 Impact Scope Investigation

Direct API usage in this codebase:

• astro.config.ts:1: import react from '@astrojs/react'
• astro.config.ts:21: integrations: [sitemap(), react()] — called with no arguments
• ✅ No babel option used → v7 breaking change does NOT apply
• ✅ No getContainerRenderer import from @astrojs/react root → v6 deprecation does NOT apply

Transitive dependency impact (significant concern):

• @vitejs/plugin-react: 5.2.0 (Vite 7) → 6.1.2 (Vite 8) — internal to @astrojs/react
• vite@8.3.3 is added to the lockfile; vite@7.3.2 remains (still required by astro@6.4.8)
• @tailwindcss/vite@4.3.3 peer dep resolution: vite@7.3.2 → vite@8.3.3
• vitest@4.1.11 peer dep resolution: vite@7.3.2 → vite@8.3.3
• All @babel/* packages removed from lockfile (Oxc replaces Babel for JSX)

Risk: Vite 7/8 coexistence
After this PR, both vite@7.3.2 (for astro@6.4.8 internals) and vite@8.3.3 (for @astrojs/react@7.0.0 and peer deps of @tailwindcss/vite, vitest) coexist. The @tailwindcss/vite plugin is registered in astro.config.ts under vite.plugins, meaning it runs in Astro's Vite context. If Astro 6.4.8 exposes a Vite 7 instance at runtime, but @tailwindcss/vite was resolved against Vite 8, there could be plugin API mismatches. This requires a real build to validate.

💡 Recommended Actions

1. Run a full production build (pnpm build) to verify Astro + @tailwindcss/vite (on Vite 8 peer) works correctly inside Astro's Vite 7 context.
2. Run all tests (pnpm test:tools && pnpm test:libs) — vitest now runs on Vite 8, which could expose test failures.
3. Verify React component rendering — the move from Babel to Oxc for JSX transformation is transparent in most cases, but fast-refresh behavior and edge cases in JSX transforms should be smoke-tested in dev mode (pnpm dev).
4. If build/tests pass, this PR can be merged without code changes — no babel option migration is needed.
5. If @tailwindcss/vite or vitest encounter Vite version mismatch issues, consider pinning vite@8 explicitly in package.json to stabilize the peer dep resolution.
