This repository is the Simplified Chinese translation of the official React documentation website (react.dev). It is a Next.js static site (Pages Router) that serves MDX-based documentation with interactive code examples via Sandpack, including a sophisticated React Server Components (RSC) sandbox that runs user code in a Web Worker inside an iframe. The site features Algolia DocSearch, RSS feed generation, an error decoder page that fetches React error codes from GitHub, and custom ESLint rules that lint markdown code blocks using the React Compiler. The architecture is a standard Next.js static site with custom remark/rehype plugins, a component library for MDX (challenges, diagrams, callouts, etc.), and a layout system with sidebar navigation and table of contents. The repository is actively maintained and synchronized with the upstream react.dev repository, with translations managed via a dedicated process.
