SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Bun provides a fast, all-in-one JavaScript runtime and toolkit that combines a runtime, package manager, bundler, and test runner to streamline development and deployment.

Core Features & Use Cases

  • Runtime: Drop-in Node-compatible runtime (built on JavaScriptCore, implemented in Zig).
  • Package manager: bun install is significantly faster than npm/yarn; lockfile is bun.lock (text) by default in current Bun; older versions used bun.lockb (binary).
  • Bundler: Built-in bundler and transpiler for apps and libraries.
  • Test runner: Built-in bun test with Jest-like API.
  • Migration & Vercel: Guidance for migrating from Node and deploying Bun on Vercel.

Quick Start

Use Bun to initialize your project and start using bun install and bun run to manage dependencies and run scripts.
