In React Labs posts, we write about projects in active research and development. We’ve made significant progress since our last update, and we’d like to share our progress. React Compiler is no longer a research project and powers instagram.com in production. Weve invested in building an optimizing compiler for React, which can re-render just the right parts of the UI when state changes. The compiler models both the rules of JavaScript and the rules of React to optimize code safely. Were testing against Metas codebase and recommend enabling Strict Mode and configuring Reacts ESLint plugin for better code quality. Check out our talk for more information on React Compiler.
