This product is a structured backend training focused on understanding how Express.js handles requests internally. Instead of copying snippets, you’ll learn how a request enters the server, passes through logic layers, and produces a response.

The course breaks Express into clear parts so you understand how backend applications are organized in real projects. You’ll see how routes, middleware, and handlers work together to form predictable and maintainable server logic.

This training is designed to remove confusion and replace it with a clear mental model of how Express-based backends operate.
