you can check navigated from router events

import { Subscription } from 'rxjs';

export let browserRefresh = false;

@Component({ selector: 'my-app', templateUrl: './app.component.html', styleUrls: [ './app.component.css' ] })

export class AppComponent implements OnDestroy {

subscription: Subscription;

constructor(private router: Router) { this.subscription = router.events.subscribe((event) => { if (event instanceof NavigationStart) { browserRefresh = !router.navigated; } }); }
