Express.js for Web APIs
Express.js is the minimal, flexible Node.js framework behind many production APIs and web applications. Its middleware model makes it easy to extend, but it requires discipline to keep routing, error handling, and structure maintainable.
The resources below cover routing, middleware, error handling, security, validation, and deployment. Each recipe shows how to build Express applications that are clean, secure, and ready for production traffic.
Every resource includes clear explanations, copy-paste code, and practical warnings. Use them to make informed decisions, avoid production pitfalls, and speed up your delivery. If you are just getting started, read the beginner-friendly articles first; if you are experienced, jump straight to the advanced patterns and architecture guides. New resources are added regularly, so bookmark this page and check back for the latest patterns.
