Description

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 url: string = route.snapshot.url.join('');
    const user = route.snapshot.data.user;
  }
}

Constructor

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;
}

Properties
