Node.js has served backend developers well for over a decade. But Bun is a rethink - built on JavaScriptCore, written in Zig, and designed to run TypeScript natively without a separate compiler step. Pair it with ElysiaJS, the framework that turns your route schemas into end-to-end TypeScript types automatically, and you get a backend stack that is both fast to run and fast to build.
This book takes you from a blank directory to a fully containerized, monitored, and deployed production API. Every chapter builds on the previous one, and every concept is grounded in real production decisions.
**What you'll build:**
A complete production API with JWT authentication and refresh token rotation, PostgreSQL with Drizzle ORM and proper migrations, Redis cache-aside pattern, WebSocket rooms with Bun's native pub/sub, file uploads to S3-compatible storage, sliding window rate limiting, structured logging with Pino, health checks and readiness probes, multi-stage Docker builds, Caddy reverse proxy with automatic TLS, and zero-downtime deployment.
**What makes this book different:**
Most TypeScript backend books show you the happy path. This book shows you what production code actually looks like - how you structure an application that needs to grow, how you handle the failure modes that don't appear in tutorials, and how you operate a Bun service in a real environment.
All code was verified against Bun 1.1.38 and ElysiaJS 1.1.25. When behavior changes between versions, it's called out explicitly.
