RouterState is a route tree. This tree's nodes are aware of the "consumed" URL segments, retrieved arguments, and processed data. You may use the Router service and the routerState property to get the current RouterState from anywhere in the application.
Example:
@Component({templateUrl:'example.html'})
class MyComponent {
constructor(router: Router) {
const state: RouterState = router.routerState;
const root: ActivatedRoute = state.root;
const child = root.firstChild;
const id: Observable<string> = child.params.map(p => p.id);
//...
}
}
