Bun Runtime provides practical instructions and examples for using Bun as a fast replacement for Node.js: installing Bun, using its package manager (bun install/add), running TypeScript directly, bundling for browser or Node targets, using Bun.serve for HTTP servers, file I/O with Bun.file, and built-in SQLite (bun:sqlite). It includes examples for programmatic bundling, the test runner, and migration notes to help teams move from Node.js workflows.
Use this skill when you want faster startup/install/test times, when building small/high-performance HTTP services, when bundling TypeScript with minimal config, or when adopting Bun as a drop-in npm/pnpm replacement. It's suited for development workflows, CI optimizations, and local prototypes where speed matters.
