Getting Started with Node.js

This course introduces the foundations of backend development using Node.js, helping you understand how modern server-side applications are built and how Node.js powers scalable, high-performance web services. You'll begin by exploring the Node.js runtime, its event-driven architecture, and how it differs from traditional backend technologies. From there, you'll set up your environment, manage packages with npm, and work with the module system using both CommonJS and ES Modules to write organized, reusable code. The course then moves into asynchronous programming, where you'll work through callbacks, Promises, and async/await to handle concurrency without blocking execution. Finally, you'll put it all together by building HTTP servers from scratch, handling routes, parsing requests, and creating your first JSON API endpoints using only core Node.js. By the end of this course, you will be able to: - Recall the core principles of the Node.js runtime, event loop, and non-blocking I/O model. - Set up a Node.js development environment and manage dependencies using npm. - Apply the module system to organize and reuse code across CommonJS and ES Modules. - Use core Node.js modules, including file system, path, and OS, to perform real operations. - Construct asynchronous workflows using callbacks, Promises, and async/await with proper error handling. - Build HTTP servers that handle routing, process client requests, and return JSON responses. Designed for aspiring backend developers, software engineering students, and frontend developers looking to expand their skills, this course provides a solid foundation for server-side development with Node.js. A basic understanding of JavaScript functions, objects, and arrays is all you need to get started. Begin your backend development journey and discover how Node.js brings the power of JavaScript to the server.
