Configure, review, or troubleshoot Rsbuild applications, including build/dev commands, assets, type checking, and bundle optimization.

Rsbuild best practices Apply these rules when writing or reviewing Rsbuild projects. Configuration Use rsbuild.config.ts and defineConfig Use tools.rspack or tools.bundlerChain only when no first class Rsbuild option exists Define explicit source.entry values for multi page applications In TypeScript projects, prefer tsconfig.json path aliases first CLI Use rsbuild for local development Use rsbuild build for production build Use rsbuild preview only for local production preview Use rsbuild inspect to inspect final Rsbuild/Rspack configs Type checking Use @rsbuild/plugin type check for integrated dev/build type checks Or run tsc noEmit / vue tsc noEmit as an explicit script step Bundle size optimization Prefer dynamic import() for non critical code paths Prefer lightweight libraries where possible Keep browserslist aligned with real compatibility requirements Asset management Import source managed assets from project source directories, not from public Reference public files by absolute URL path Security Do not publish .map files to public servers/CDNs when production source maps are enabled Debugging Run with DEBUG=rsbuild when diagnosing config resolution or plugin behavior Read generated files in dist/.rsbuild to confirm final config, not assumed config Profiling Use Node CPU profiling ( cpu prof ) when JavaScript side overhead is suspected Use RSPACK PROFILE=OVERVIEW and analyze trace output for compiler phase bottlenecks Documentation For the latest (v2) docs, read http://rsbuild.rs/llms.txt For Rsbuild v1 docs, read http://v1.rsbuild.rs/llms.txt
