RouterStateSnapshot

Represents the state of the router at a moment in time.

This is a tree of activated route snapshots. Every node in this tree knows about the "consumed" URL segments, the extracted parameters, and the resolved data.

The following example shows how a component is initialized with information from the snapshot of the root node's state at the time of creation.

@Component({templateUrl:'template.html'})class MyComponent { constructor(router: Router) { const state: RouterState = router.routerState; const snapshot: RouterStateSnapshot = state.snapshot; const root: ActivatedRouteSnapshot = snapshot.root; const child = root.firstChild; const id: Observable<string>= child.params.map(p => p.id); //... }}
