🚀 Build a Production-Ready Chat App Backend with Bun + Hono + TypeScript

Description

In this video, we **build a full-stack chat application backend** using modern tools and production-ready practices. To begin, we configure a blazing-fast backend environment with **Bun** and **Hono**, establish a clean project architecture, and set up essential developer tools like **ESLint** and **Prettier**. Moving forward, we implement the complete backend infrastructure, including **JWT authentication**, **password hashing with Argon2id**, **REST APIs**, **chat room creation**, and **real-time message handling logic**. Next, our focus shifts to **testing and validation**, where we integrate **Zod schema validation** and write high-performance integration tests using **Bun’s built-in test runner** to ensure reliability and achieve **over 90% code coverage**. Finally, we take the backend to a **production-ready level** with advanced security features such as **rate limiting, caching middleware, CORS, DoS protection**, and **structured logging with Pino**. This series is perfect for developers who want to learn how to build **fast, scalable, and secure backend systems** with modern JavaScript tooling. ### 📌 What You’ll Learn * ✅ Backend setup with Bun * ✅ Lightweight API development with Hono * ✅ Type-safe architecture using TypeScript * ✅ JWT authentication system * ✅ Secure password hashing with Argon2id * ✅ REST API routing for chats and messages * ✅ Request validation with Zod * ✅ Integration testing with Bun test runner * ✅ Rate limiting and request throttling * ✅ Caching strategies for API optimization * ✅ Structured logging with Pino * ✅ Production-level backend best practices This video will help you **master modern backend engineering** by building a complete chat application backend from scratch using **Bun, Hono, and TypeScript**. From setup and authentication to testing, caching, logging, and production security, this content provides a **real-world roadmap for building scalable APIs like a professional backend developer**. 🔥 Perfect for **full-stack developers, backend engineers, and JavaScript/TypeScript learners**.
