Sourced from @​vitejs/plugin-react-swc's releases.

plugin-react@4.1.0

• Add @types/babel__cores to dependencies (fix #211)
• Improve build perf when not using Babel plugins by lazy loading @babel/core #212
• Better invalidation message when an export is added & fix HMR for export of nullish values #215
• Include non-dev jsx runtime in optimizeDeps & support HMR for JS files using the non dev runtime #224
• The build output now contains a index.d.cts file so you don't get types errors when setting moduleResolution to node16 or nodenext in your tsconfig (we recommend using bundler which is more close to how Vite works)

plugin-react-swc@4.1.0

Set SWC cacheRoot options

This is set to {viteCacheDir}/swc and override the default of .swc.

Perf: simplify refresh wrapper generation (#835)

plugin-react@4.0.4

• Fix #198: Enable Babel if presets list is not empty

plugin-react@4.0.3

• Revert #108: Remove throw when refresh runtime is loaded twice to enable usage in micro frontend apps. This was added to help fix setup usage, and this is not worth an annoying warning for others or a config parameter.

plugin-react@4.0.2

• Fix fast-refresh for files that are transformed into jsx (#188)

plugin-react@4.0.1

• Support Vitest deps.experimentalOptimizer
• Support using components inside web workers (#181)

plugin-react-swc@4.0.1

Set optimizeDeps.rollupOptions.transform.jsx instead of optimizeDeps.rollupOptions.jsx for rolldown-vite (#735)

optimizeDeps.rollupOptions.jsx is going to be deprecated in favor of optimizeDeps.rollupOptions.transform.jsx.

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).

Perf: simplify refresh wrapper generation (#835)

4.0.1 (2025-08-19)

Set optimizeDeps.rollupOptions.transform.jsx instead of optimizeDeps.rollupOptions.jsx for rolldown-vite (#735)

optimizeDeps.rollupOptions.jsx is going to be deprecated in favor of optimizeDeps.rollupOptions.transform.jsx.

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.
