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

[email protected]

• 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)

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

[email protected]

• Revert #108: Remove throw when refresh runtime is loaded twice to enable usage in micro frontend apps. This was added to help fix setup usage, and this is not worth an annoying warning for others or a config parameter.

• Fix fast-refresh for files that are transformed into jsx (#188)

• Support Vitest deps.experimentalOptimizer
• Support using components inside web workers (#181)

Options changes

include/exclude

These options 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.

jsxRuntime

The support for React auto import when 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.

Removed options

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

Perf

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)
