How Not to Node.js. A handbook to avoid common Node.js pitfalls and build cleaner, faster, and production-ready apps

Node. js makes it easy to get started, but just as easy to get things wrong. How Not to Node. js takes a practical, no-nonsense approach to uncovering the most common mistakes developers make, and shows you exactly how to avoid them. The book is structured around real-world anti-patterns, guiding you through how to identify, understand, and fix problematic code. You’ll start by learning how patterns and anti-patterns shape application design, before diving into asynchronous pitfalls, event loop behavior, and error handling. As you progress, you’ll explore architectural concerns such as logging, middleware design, environment management, and API reliability. By the end, you won’t just know how to write Node. js code, you’ll know how to avoid writing bad Node. js code, building applications that are clean, scalable, and production-ready.
