Bun Runtime

Overview

Bun is an all-in-one JavaScript runtime designed for speed, with built-in package manager, test runner, and bundler. This skill should be invoked when you need fast JavaScript/TypeScript execution, a streamlined development experience, or want to reduce toolchain complexity.

Core Principles

• All-in-One: Use Bun for runtime, package management, testing, and building
• Speed First: Bun is significantly faster than Node.js for most operations
• Node Compatibility: Most Node.js code works with Bun
• Built-in APIs: Use Bun's native APIs (Bun.file, Bun.serve, etc.)
