Building Web APIs with Express.js

Building scalable back-end services is a core skill for any modern web developer. Express.js provides the essential tools to handle requests, manage routes, and deliver data efficiently without the complexity of larger frameworks. This course takes you through the logic of server-side development, transforming you from a beginner into a developer capable of structuring professional applications. You will learn to create robust APIs that are easy to maintain and ready for the modern web. What you'll learn: - Understand core Express.js architecture and the Node.js runtime environment. - Configure routes using HTTP methods to handle diverse client requests. - Implement custom middleware to manage authentication, logging, and data processing. - Apply modern asynchronous patterns with async/await for cleaner, non-blocking code. - Practice error handling and basic security measures to protect your API endpoints. - Manage environment variables and project configurations for different development stages. The curriculum moves from basic terminology and project setup to advanced routing logic and middleware implementation. You will read through detailed explanations and code examples that demonstrate how to organize your back-end logic into a professional, scalable structure. This course is designed for beginners with a basic knowledge of JavaScript who are ready to transition into back-end programming. No prior experience with server-side development is required.
