Table of contents
Definition
A Web router is part of a web system that is responsible for mapping URLs [→] to content or pages.
Routing is the process of doing so.
Use Cases and Examples
Most Content Management Systems [↗] come with routing systems that dynamically match URLs to their content.
This mapping in most systems is done by converting the title of the article into a URL slug [→].
Routers in web apps are used to move a user to different pages as they navigate their way. Routers in web apps, however, do a lot more than just move the user around. They can also carry data and send this back to be processed by the app.
This can take the form of a query parameter [→] or path parameter [→].
Summary
If moving across the web is using roads, routers are the maps that guide us towards our destination.
