The Angular Router raises events when it navigates from one route to another route.

Some of the useful events are route change start ( NavigationStart ) and route change end ( NavigationEnd). In this tutorial, we learn what is router events are and how to listen to them using Example code.
The RouterLinkActive is a directive for adding or removing classes from an HTML element that is bound to a RouterLink.

In this article, we will show you how to implement lazy loading
