v3.11.0

Compare Source

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' }))

v3.10.2

Compare Source

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.

v3.10.1

Compare Source

Add explicit semicolon in preambleCode #​485

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

v3.10.0

Compare Source

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 "/@&#8203;react-refresh" points to missing source files and is unnecessary in test mode.

Skip HMR for JSX files with hooks #​480

This removes the HMR warning for hooks with JSX.

v3.9.0

Compare Source

Make compatible with rolldown-vite

This plugin is now compatible with rolldown-powered version of Vite.

v3.8.1

Compare Source

Remove WebContainers warning #​268

SWC is now supported in WebContainers 🎉

v3.8.0

Compare Source

Add useAtYourOwnRisk_mutateSwcOptions option

The future of Vite is with OXC, and from the beginning this was a design choice to not exposed too many specialties from SWC so that Vite React users can move to another transformer later.
Also debugging why some specific version of decorators with some other unstable/legacy feature doesn't work is not fun, so we won't provide support for it, hence the name useAtYourOwnRisk.

react({
  useAtYourOwnRisk_mutateSwcOptions(options) {
    options.jsc.parser.decorators = true;
    options.jsc.transform.decoratorVersion = "2022-03";
  },
});
