Bun Development

This is a comprehensive guide to working with Bun, the fast JavaScript runtime that's gained traction as a Node.js alternative. It covers the full development cycle: installation, project scaffolding, package management that's genuinely faster than npm, and running TypeScript without a build step. The built-in APIs section is especially practical, showing Bun's native HTTP server, WebSocket support, SQLite integration, and file handling. You'd reach for this when starting greenfield projects where speed matters, or when you're curious about migrating existing Node.js apps. The testing and bundling sections get cut off in the source, but there's enough here to get productive quickly.
