This product is a practical introduction to Express.js, created for developers who want to understand how backend applications actually work, not just follow code examples.

The course explains how Express is used to build real servers on top of Node.js and how incoming requests move through an application. You’ll learn how backend logic is structured, how routing works, and why middleware is the core concept behind Express-based systems.

Instead of treating Express as a black box, this training focuses on clarity: how requests are received, processed, and handled step by step, the same way it happens in real projects.
