Gain insights into Express.js essentials, routing, middleware, and RESTful APIs. Learn to integrate MongoDB, JWT authentication, validation, real-time features, and logging for scalable back-end apps.

Become a MERN Stack Developer

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.

This module begins with a quick review of Node.js and asynchronous JavaScript. Then, we’ll cover Express.js essentials like routing, middleware, and modular app structure. We’ll learn to build RESTful APIs, connect our app to a database, and implement JSON web tokens (JWT) authentication. We’ll also explore validation and sanitization for added security. Finally, we’ll understand templating engines, real-time features using Socket.IO, and structured logging using Winston.

By the end of this module, we'll have a solid grasp of Express.js and the confidence to build secure, scalable, production-ready backend applications tailored to our own learning goals.
