React Compiler

[samesfahani-tuplehealth]

Will there be instructions on how to use the new React Compiler given that it's babel based?

[ArnaudBarre]

For now the simplest way is to switch back to the Babel plugin. They working a Rust port, I hope this can be builtin in SWC in the future!

how can I New React Compiler setting Vite project, now?
I try to rewrite "vite.config.ts" file (plus plugins section) .....
but the "babel" letter makes errors

[alireza-akbarzadeh]

You should use vite-plugin-react

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

const ReactCompilerConfig = {};

export default defineConfig({
  plugins: [
    react({
      babel: {
        plugins: [["babel-plugin-react-compiler", ReactCompilerConfig]],
      },
    }),
  ],
});

Will be there an option to use react compiler with SWC in the future?

[ArnaudBarre]

If the React team lands the Rust port of the compiler, I think SWC will try to integrate it directly. But the rust part didn't get updated since annouced: https://github.com/facebook/react/commits/main/compiler/crates

[AaronDewes]

The Rust port has been removed: facebook/react#32219

For React Compiler though, we plan to continue using JavaScript and explore lightweight native wrappers for things like OXC and SWC plugins.

[ArnaudBarre]

Yeah, they still plan to have some integrations, but it will probably take times too
