plugin-react@4.0.0

Options changes

include/exclude

These options now allow to completely override the files processed by the plugin (#122). This is more in line with other Rollup/Vite plugins and simplify the setup of enabling Fast Refresh for .mdx files. This can be done like this:

export default defineConfig({
  plugins: [
    { enforce: 'pre', ...mdx() },
    react({ include: /\.(mdx|js|jsx|ts|tsx)$/ }),
  ],
})

These changes also allow to apply Babel plugins on files outside Vite root (expect in node_modules), which improve support for monorepo (fix #16).

With these changes, only the file extensions is used for filtering processed files and the query param fallback is removed.

jsxRuntime

The support for React auto import when using classic runtime is removed. This was prone to errors and added complexity for no good reason given the very wide support of automatic runtime nowadays. This migration path should be as simple as removing the runtime option from the config.

Removed options

• fastRefresh (#122) This should be correctly activated by plugin without configuration.
• jsxPure (#129) This is a niche use case that was just passing down the boolean to esbuild.jsxSideEffects.

Perf

This release goes in hand with the upcoming Vite 4.3 release focusing on performances:

• Cache plugin load (#141)
• Wrap dynamic import to speedup analysis (#143)

Other notable changes

• Silence "use client" warning (#144, fix #137)
• Fast Refresh is applied on JS files using automatic runtime (#122, fix #83)
• Vite 4.2 is required as a peer dependency (#128)
• Avoid key collision in React refresh registration (a74dfef, fix #116)
• Throw when refresh runtime is loaded twice (#108, fix #101)
• Don't force optimization of jsx-runtime (#132)

4.0.0 (2025-08-07)

4.0.0-beta.0 (2025-07-28)

Require Node 20.19+, 22.12+

This plugin now requires Node 20.19+ or 22.12+.

3.11.0 (2025-07-18)

Add HMR support for compound components (#518)

HMR now works for compound components like this:

const Root = () => <div>Accordion Root</div>
const Item = () => <div>Accordion Item</div>
export const Accordion = { Root, Item }

Return Plugin[] instead of PluginOption[] (#537)

The return type has changed from react(): PluginOption[] to more specialized type react(): Plugin[]. This allows for type-safe manipulation of plugins, for example:

// previously this causes type errors
react()
  .map(p => ({ ...p, applyToEnvironment: e => e.name === 'client' }))

3.10.2 (2025-06-10)

Suggest @vitejs/plugin-react-oxc if rolldown-vite is detected #491

Emit a log which recommends @vitejs/plugin-react-oxc when rolldown-vite is detected to improve performance and use Oxc under the hood. The warning can be disabled by setting disableOxcRecommendation: true in the plugin options.

Use optimizeDeps.rollupOptions instead of optimizeDeps.esbuildOptions for rolldown-vite #489

This suppresses the warning about optimizeDeps.esbuildOptions being deprecated in rolldown-vite.

Add Vite 7-beta to peerDependencies range #497

React plugins are compatible with Vite 7, this removes the warning when testing the beta.

3.10.1 (2025-06-03)

Add explicit semicolon in preambleCode #485

This fixes an edge case when using HTML minifiers that strips line breaks aggressively.
