Fix HMR for compound components (#1484)

Adding or removing a component from a compound component was not handled, creating stale updates. Doing this now triggers hmr invalidate on the file and propagates the invalidation to importers.

Fix compiler.logDiagnostics option not working (#1483)

With oxc-transform-react >= 0.148, the logDiagnostics was not working. This version fixes it and requires oxc-transform-react >= 0.152 as a peer dependency if you are using the compiler option. compiler.logDiagnostics option is now deprecated and should be swapped for the builtin compiler.reportDiagnostics.

Disable refresh for non-jsx with compiler enabled (fix #1478) (#1485)

When the compiler was enabled, TS files could trigger fast refresh which would cause runtime errors. The logic now follows what the builtin oxc plugin in Vite does.

Add compiler.logDiagnostics option

Recoverable React Compiler diagnostics are no longer logged by default. Set compiler.logDiagnostics to true to log them through Vite. Fatal diagnostics are always logged and fail the transform.

Respect environment sourcemap option for React Compiler transform when builder.sharedPlugins is enabled (#1439)

The React Compiler transform was using the top-level sourcemap option instead of the environment sourcemap option. This caused a problem when the experimental builder.sharedPlugins was enabled.

Add experimental native React Compiler support (#1419)

Add experimental native React Compiler support.

You can use it by installing oxc-transform-react and enabling it via the compiler option:

npm install -D oxc-transform-react

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'

export default defineConfig({
  plugins: [
     react({ compiler: true })
  ]
})
