TUsage Notes
Every node in the route tree is an ActivatedRoute instance
that knows about the "consumed" URL segments, the extracted parameters,
and the resolved data.
Use the ActivatedRoute properties to traverse the tree from any node.
The following fragment shows how a component gets the root node of the current state to establish its own route tree:
@Component({templateUrl:'template.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); //... }}Jump to details
