Node.js and Express: Build REST APIs and Real-Time Apps

Backend development is the backbone of modern web applications, powering everything from user authentication to real-time communication. If you want to build fast, scalable server-side systems, learning Node.js is the most effective way to leverage your JavaScript skills on the server. This text-only course guides you from backend basics to building functional, real-world services. You will start with the core concepts of Node.js, understand its event-driven architecture, and move on to building robust REST APIs and interactive, real-time applications. What you'll learn: - Understand the foundations of Node.js, including the event loop, asynchronous programming, and modern ES Modules. - Build scalable backend servers and routing systems using the Express framework. - Configure secure databases using MongoDB and manage data flow with Mongoose. - Design and implement stateless REST APIs with proper routing, validation, and error handling. - Create real-time, bi-directional communication systems using Socket.io for interactive applications. - Apply modern backend practices, including environment variable management and clean async/await patterns. The course begins with essential terminology and the setup of your development environment, gradually progressing from basic routing to database integration and real-time communication. You will read structured explanations, study practical code snippets, and complete written exercises to solidify your backend skills. This course is designed for beginners who have a basic understanding of JavaScript and want to transition into backend development. No prior server-side experience is required.
