• 1 You can use pairwise like shown in stackoverflow./questions/33520043/… and store the current and previous value in a service – Günter Zöchbauer Commented May 4, 2017 at 9:01

UPDATED for Angular 6

Insert the code below to your parent ponent, which contains your 2 ponents:-

import { Router, RoutesRecognized } from "@angular/router";
import { filter, pairwise } from 'rxjs/operators';

previousUrl:string;

constructor(private router: Router) {

    router.events
        .pipe(
          filter(event => event instanceof RoutesRecognized),
          pairwise()
        )            
        .subscribe((e: any) => {
            this.previousUrl = e[0].urlAfterRedirects;
        });
}

It worked for me, I hope it will work for you as well.
