Routing is the chore of responding to changes in the URL caused by adding and deleting content from a single-page frontend application. This is a difficult operation since we must first intercept a request that changes the browser’s URL in order to prevent the browser from reloading. Then we must decide which material to remove and which content to add, and we must also modify the browser’s URL to display the user the current page they are on.
As we can see, this is a tough task to accomplish, especially when dealing with several apps. That’s why Angular has a complete single-page application routing solution. This allows us to specify routes with matching components and delegate the routing process to Angular.
