plugin-react-swc@3.11.0

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' }))

plugin-react-swc@3.10.2

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: false 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.

plugin-react-swc@3.10.1

Add explicit semicolon in preambleCode #485

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

plugin-react-swc@3.10.0

Add filter for rolldown-vite #470

Added filter so that it is more performant when running this plugin with rolldown-powered version of Vite.

Skip HMR preamble in Vitest browser mode #478

This was causing annoying Sourcemap for "/@react-refresh" points to missing source files and is unnecessary in test mode.

Skip HMR for JSX files with hooks #480
