Express.js is a popular Node.js framework, especially useful for building APIs and server-side apps. It’s lightweight, unopinionated, and flexible, giving you full control over how your app is structured. Whether new to backend development or ready to build production-grade services using JavaScript, Express is a great place to start. In this course, you’ll begin with a quick review of Node.js and asynchronous JavaScript. Then, you’ll cover Express.js essentials like routing, middleware, and modular app structure. You’ll learn to build RESTful APIs, connect your app to a database, and implement JSON web tokens (JWT) authentication. You’ll also explore validation and sanitization for added security. Finally, you’ll understand templating engines, real-time features using Socket.IO, and structured logging using Winston. After completing this course, you’ll have a solid grasp of Express.js and the confidence to build secure, scalable, production-ready backend applications from scratch.
