v4.3.4

Add Vite 6 to peerDependencies range

Vite 6 is highly backward compatible, not much to add!

Force Babel to output spec compliant import attributes #386

The default was an old spec (with type: "json"). We now enforce spec compliant (with { type: "json" })

v4.3.3

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 } })],
  }
})

v4.3.2

Ignore directive sourcemap error #369

v4.3.1

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

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

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

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.

v4.1.1

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

v4.1.0

• 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)

v4.0.4

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