Fast, modern JavaScript/TypeScript development with the Bun runtime, inspired by oven-sh/bun . Use this skill when: - Native TypeScript and JSX support with no transpiler required; 10-100x faster package installation and ~25ms startup time compared to Node.js - Built-in tools: HTTP/WebSocket server, SQLite database, test runner, bundler, and password hashing via Bun.serve() , Bun.sql() , bun test , and Bun.build() - File system and environment variable APIs ( Bun.file() , auto-loaded .env ) plus executable compilation for standalone CLI tools across Linux, macOS, and ARM64 - High Node.js compatibility for most APIs ( fs , path , crypto , process , Buffer ); migration involves swapping package manager and updating scripts in package.json - Starting new JS/TS projects with Bun - Migrating from Node.js to Bun - Optimizing development speed - Using Bun's built-in tools (bundler, test runner) - Troubleshooting Bun-specific issues - Bun Documentation - Bun GitHub - Elysia Framework - Bun Discord - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety...
