There was a problem hiding this comment.
I'm wondering if we would not have better stability by always using oxc-transform-react. You could then remove react refresh from the builtin oxc-transform, making it a lot more vendor neutral.
That's a trade off, because it would be a bit slower for people not using the compiler, but in my experience the overhead is not visible in real Vite application (and in build mode without compiler, the builtin transform could still be used)

…in-react main vitejs/vite-plugin-react#1419 is merged (f1340b0c); the tarball now builds from that canonical commit instead of the fork PR head (the only source change is an @experimental JSDoc tag on the compiler option). The npm release is queued as @vitejs/plugin-react@6.1.0 in vitejs/vite-plugin-react#1428 — vendor/README.md tracks the swap plan. Co-authored-by: Cody Olsen <stipsan@users.noreply.github.com>

Add a
compileroption backed by the optionaloxc-transform-reactpackage.When enabled,
oxc-transform-reactowns the React Compiler, TypeScript/JSX, and Fast Refresh transforms in one pass, while Rolldown React transforms are disabled. React Compiler and Fast Refresh remain client-only; server environments use the same package for TypeScript/JSX.Keeping React Compiler in a separate package avoids adding framework-specific compiler size and complexity to Rolldown.
