    class ActivatedRouteSnapshot {}

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;  }}

params

Params

The matrix parameters scoped to this route.

You can compute all params (or data) in the router state or to get params outside of an activated component by traversing the RouterState tree as in the following example:

          collectRouteParams(router: Router) {  let params = {};  let stack: ActivatedRouteSnapshot[] = [router.routerState.snapshot.root];  while (stack.length > 0) {    const route = stack.pop()!;    params = {...params, ...route.params};    stack.push(...route.children);  }  return params;}
