Setup

• bun init - create project

• bun run dev - run dev server
• bun test - Jest/Vitest compatible
• bun build - production bundling

API Development

• Native Bun.serve() for HTTP server
• Bun.file() for file operations
• .ts and .js natively - no transpiler
• JSON: await req.json(), Response.json(data)
• SQLite built-in: import { Database } from "bun:sqlite"
• Password hashing: Bun.password.hash()
• Lockfile: bun.lock
