When you develop both a frontend or backend application, you want to define different logic flows that can be reached by using different paths. For this reason, when you choose a programming language and a framework to work with, one of the most important things is the routing. As the word describes, routing means to route the traffic to a certain target.

When defining routes, the resources you are exposing through a path will be reached by performing an HTTP request. Because of this, you always need to associate an HTTP method with a route. ExpressJS lets you define routing and routers in a very easy and efficient way, so you can manage all your paths very clearly.

In this lab, you will understand the basics of the ExpressJS routing system, you will define some routes, and you will create a router to better handle specific routes.
