Learn Node.js

Modern applications rely on fast, scalable backend services, and Node.js has become one of the most widely used platforms for building them. From APIs and microservices to real-time applications, companies expect developers to understand asynchronous programming, networking, and production-ready server architecture. This course provides a structured path to developing the Node.js skills used in modern backend engineering. I built this course from my experience working on large-scale distributed systems for seven years at Microsoft, and later co-founding Educative. One challenge I consistently observed was that many developers could build simple Node.js applications but struggled to understand what happens behind the scenes. Rather than focusing only on frameworks, this course emphasizes the core runtime concepts that help you reason about performance, scalability, and maintainability. You'll begin by learning Node.js fundamentals, modules, and server-side JavaScript before diving into asynchronous programming with callbacks, Promises, async/await, and the event loop. From there, you'll explore event-driven programming, file systems, buffers, streams, HTTP servers, routing, REST APIs, PostgreSQL integration, JWT authentication, WebSockets, and automated testing with Jest. Throughout the course, interactive lessons and hands-on exercises reinforce each concept, culminating in a capstone project in which you'll build a production-style REST API capable of storing, filtering, and serving JSON data in multiple formats. Thousands of developers have used Educative's interactive learning platform to build practical software engineering skills and advance their careers. If you want to become a confident Node.js backend developer who understands not just how to write code but why it works, this course is the right place to start.
