Bumps @vitejs/plugin-react-swc from 3.7.0 to 4.2.1.

Release notes

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

plugin-react@4.2.1

Remove generic parameter on Plugin to avoid type error with Rollup 4/Vite 5 and skipLibCheck: false.

I expect very few people to currently use this feature, but if you are extending the React plugin via api object, you can get back the typing of the hook by importing ViteReactPluginApi:

import type { Plugin } from 'vite'
import type { ViteReactPluginApi } from '@vitejs/plugin-react'
export const somePlugin: Plugin = {
name: 'some-plugin',
api: {
reactBabel: (babelConfig) => {
babelConfig.plugins.push('some-babel-plugin')
},
} satisfies ViteReactPluginApi,
}

plugin-react-swc@4.2.1

Fix @vitejs/plugin-react-swc/preamble on build (#962)

plugin-react@4.2.0

Update peer dependency range to target Vite 5

There were no breaking change that impacted this plugin, so any combination of React plugins and Vite core version will work.

Align jsx runtime for optimized dependencies

This will only affect people using internal libraries that contains untranspiled JSX. This change aligns the optimizer with the source code and avoid issues when the published source don't have React in the scope.

Reminder: While being partially supported in Vite, publishing TS & JSX outside of internal libraries is highly discouraged.

plugin-react-swc@4.2.0

Add @vitejs/plugin-react-swc/preamble virtual module for SSR HMR (#890)

SSR applications can now initialize HMR runtime by importing @vitejs/plugin-react-swc/preamble at the top of their client entry instead of manually calling transformIndexHtml. This simplifies SSR setup for applications that don't use the transformIndexHtml API.

Use SWC when useAtYourOwnRisk_mutateSwcOptions is provided (#951)

Previously, this plugin did not use SWC if plugins were not provided even if useAtYourOwnRisk_mutateSwcOptions was provided. This is now fixed.

plugin-react@4.1.1

• Enable retainLines to get correct line numbers for jsxDev (fix #235)

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
