How do I detect user navigating back in Angular2?

Question

I have a component and I need to detect if user pressed back button in his browser to navigate back.

Currently I\'m subscribing router events.

constr         


        

Answer 1

IMO better method of listenting for popstate events is to subscribe to location service

import {Location} from "@angular/common";

constructor(private location: Location) { }

ngOnInit() {
    this.location.subscribe(x => console.log(x));
}

It doesn't use PlatformLocation directly (as documentation suggest) and you can unsubscribe any time you want.
