Bun

Fast JS/TS runtime with native bundling, testing, package management.

When to Use

• Running JS/TS apps that benefit from fast startup and native TS support
• Using Bun's built-in bundler, test runner, or package manager
• Writing HTTP servers, scripts, or CLI tools
• Don't use for: full Node.js API compat, native C++ addons, LTS stability

Critical Patterns

✅ REQUIRED: Bun.serve() for HTTP Servers

Built-in HTTP with streaming, no framework needed.
