Port React Compiler to Rust
Meta's React team opens a PR to rewrite the React Compiler in Rust for significant build performance gains.
The React core team has submitted a pull request to port the React Compiler from JavaScript to Rust, following the broader trend of frontend tooling rewrites. React Compiler automatically inserts memoization into React components at build time; a Rust rewrite would dramatically speed up compilation in large codebases. This mirrors moves by SWC, Turbopack, Rolldown, and Biome, signaling that the entire React build pipeline may eventually run on Rust.
React Compiler 是 Meta 開源團隊多年研發的靜態分析與自動優化工具，最初以「React Forget」為代號，於 React 19 周期正式亮相。其核心功能是在建置期靜態分析 React 元件與 Hook 的資料流，自動插入 `useMemo`、`useCallback` 等記憶化邏輯，讓開發者無需手動管理依賴陣列，也能獲得媲美精心調校後的效能表現。
