Rslib Best Practices

Apply these rules when writing or reviewing Rslib library projects.

Configuration

• Use rslib.config.ts and defineConfig
• Check Rslib-specific configurations first (e.g., lib.*), and also leverage Rsbuild configurations (e.g., source.*, output.*, tools.*) as needed
• For deep-level or advanced configuration needs, use tools.rspack or tools.bundlerChain to access Rspack's native configurations
• In TypeScript projects, prefer tsconfig.json path aliases

CLI

• Use rslib to build
• Use rslib --watch to build in watch mode for local development
• Use rslib inspect to inspect final Rslib/Rsbuild/Rspack configs
