Building RESTful APIs with Node.js and Express

Behind every modern web and mobile application sits a robust API powering the data flow. Understanding how to build these server-side systems is an essential skill for any aspiring backend developer. This text-based course guides you through the process of building reliable, maintainable RESTful APIs from scratch. You will transition from writing basic client-side JavaScript to structuring complete server applications that handle client requests, manage data, and respond with clean JSON. What you'll learn: - Understand foundational web server architecture, HTTP methods, and REST design principles. - Configure a Node.js development environment using modern ECMAScript Modules (ESM). - Build scalable backend routes and handle HTTP requests and responses using Express. - Implement asynchronous request handling and robust error-handling middleware. - Secure your application using environment variables and Cross-Origin Resource Sharing (CORS) configurations. - Test your API endpoints to ensure reliable and predictable behavior. You will start by exploring core web concepts and basic Node.js architecture before moving on to hands-on routing, request validation, and API structuring. Through written explanations and practical code snippets, you will build a solid foundation in backend development. This course is designed for beginners who have a basic grasp of JavaScript and want to transition into backend development. No prior experience with server-side programming or Express is required.
