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

SSR applications can now initialize HMR runtime by importing @vitejs/plugin-react/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.

Fix raw Rolldown support for Rolldown 1.0.0-beta.44+ (#​930)

Rolldown 1.0.0-beta.44+ removed the top-level jsx option in favor of transform.jsx. This plugin now uses the transform.jsx option to support Rolldown 1.0.0-beta.44+.

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({ babel: { plugins: ['babel-plugin-react-compiler'] } })
  .map(p => ({ ...p, applyToEnvironment: e => e.name === 'client' }))

v4.6.0

Add raw Rolldown support

This plugin only worked with Vite. But now it can also be used with raw Rolldown. The main purpose for using this plugin with Rolldown is to use react compiler.

v4.5.2

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.

Force Babel to output spec compliant import attributes #​386

v4.3.3

Compare Source

React Compiler runtimeModule option removed

React Compiler was updated to accept a target option and runtimeModule was removed. vite-plugin-react will still detect runtimeModule for backwards compatibility.

When using a custom runtimeModule or target !== '19', the plugin will not try to pre-optimize react/compiler-runtime dependency.

The react-compiler-runtime is now available on npm can be used instead of the local shim for people using the compiler with React < 19.

Here is the configuration to use the compiler with React 18 and correct source maps in development:

npm install babel-plugin-react-compiler react-compiler-runtime @​babel/plugin-transform-react-jsx-development

export default defineConfig(({ command }) => {
  const babelPlugins = [['babel-plugin-react-compiler', { target: '18' }]]
  if (command === 'serve') {
    babelPlugins.push(['@​babel/plugin-transform-react-jsx-development', {}])
  }

  return {
    plugins: [react({ babel: { plugins: babelPlugins } })],
  }
})

Fix support for React Compiler with React 18

The previous version made this assumption that the compiler was only usable with React 19, but it's possible to use it with React 18 and a custom runtimeModule: https://gist.github.com/poteto/37c076bf112a07ba39d0e5f0645fec43

When using a custom runtimeModule, the plugin will not try to pre-optimize react/compiler-runtime dependency.

Reminder: Vite expect code outside of node_modules to be ESM, so you will need to update the gist with import React from 'react'.

v4.3.0

Compare Source

Fix support for React compiler

Don't set retainLines: true when the React compiler is used. This creates whitespace issues and the compiler is modifying the JSX too much to get correct line numbers after that. If you want to use the React compiler and get back correct line numbers for tools like vite-plugin-react-click-to-component to work, you should update your config to something like:

export default defineConfig(({ command }) => {
  const babelPlugins = [['babel-plugin-react-compiler', {}]]
  if (command === 'serve') {
    babelPlugins.push(['@​babel/plugin-transform-react-jsx-development', {}])
  }

  return {
    plugins: [react({ babel: { plugins: babelPlugins } })],
  }
})

Support HMR for class components

This is a long overdue and should fix some issues people had with HMR when migrating from CRA.

v4.2.1

Compare Source

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,
}

v4.2.0

Compare Source

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.

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

• 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)

v4.0.0

Compare Source

This major version include a revamp of options:

• include/exclude 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.

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

The support for React auto import whe 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.

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)
