Currently in the `compiler` workspace, we invoke esbuild directly to build most packages (with the exception of `snap`). This has been mostly fine, but does not allow us to do things like generate type declaration files. I would #32416 to be able to consume the merged eslint-plugin-react-compiler from source rather than via npm, and one of the things that has come up from my exploration in that stack using the compiler from source is that babel-plugin-react-compiler is missing type declarations. I still need to test if this unblocks #32416 but this stack can be landed independently though as we could probably just release type declarations on npm. No one should be using the compiler directly, but if they really wanted to, lack of type declarations would not stop them (cf React secret internals). Note that I still kept esbuild as we still use it directly for forgive.
React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
