Description

Contains the information about a route associated with a component loaded in an outlet at a particular moment in time. ActivatedRouteSnapshot can also be used to traverse the router state tree.

The following example initializes a component with route information extracted from the snapshot of the root node at the time of creation.

          @Component({templateUrl:'./my-component.html'})class MyComponent {  constructor(route: ActivatedRoute) {    const id: string = route.snapshot.params.id;    const url: string = route.snapshot.url.join('');    const user = route.snapshot.data.user;  }}
