Summary

React Compiler Beta is published to npm under the @beta tag. It provides build-time automatic memoization and a companion ESLint plugin that surfaces Rules of React issues. The compiler now supports apps on React 17+ via the optional react-compiler-runtime, and library authors can compile and ship pre-compiled packages so consumers benefit without enabling the compiler.

Key Points

• Install (beta): npm install -D babel-plugin-react-compiler@beta eslint-plugin-react-compiler@beta or yarn add -D babel-plugin-react-compiler@beta eslint-plugin-react-compiler@beta.
• ESLint plugin recommended and usable standalone: npm install -D eslint-plugin-react-compiler@beta; enable it in your ESLint config to detect Rules of React violations before enabling the compiler.
• Backwards compatibility: set a minimum target in your compiler config and add react-compiler-runtime to support React 17/18; the runtime will polyfill the required APIs depending on the host app.
• Libraries: compile source in the library repo prior to publishing so downstream apps receive pre-compiled, memoized code without running the compiler.
• Working Group: public membership opened for community feedback; continue filing bug reports in the React repo and use the Working Group discussion forum for design feedback.
• Roadmap: experimental → public Beta (today) → Release Candidate → General Availability (Stable); future work includes merging the compiler ESLint plugin with eslint-plugin-react-hooks and additional compiler optimizations.

Actionable next steps

• Run the ESLint plugin first to catch Rules of React issues.
• Try the beta in an isolated branch or small repo, and if targeting React <19 add react-compiler-runtime and set minTarget.
• Library maintainers: compile and test before publishing to npm so consumers benefit immediately.
