bun-api

Bun runs TypeScript natively — no tsc compilation, no ts-node, no build step. Run any .ts file directly with bun file.ts. Use Bun's native APIs instead of Node.js equivalents — they're faster, more ergonomic, and require no additional dependencies.

Critical: In a Bun project (has bun.lock, bun.lockb, bunfig.toml, or @types/bun in devDependencies), always use Bun to run scripts (bun file.ts, not node file.ts) and prefer Bun-native APIs over Node.js equivalents. Mixing runtimes causes subtle bugs and unnecessary retries.

Built-in HTTP server — replaces Express, Fastify, or http.createServer.
