How to detect browser back button click in Angular2

Question

I want to clear Localstorage data on browser back button click. But how to detect browser back button click in Angular2. I am not getting any exact solution. Can anyone please tell me how to do this?

Answer 1

You can use ngOnDestroy method of components which is part of component life cycle.

This component is called whenever component is destroyed.

What you can do is create a service where your logic to clean localstorage will be written.

Call this service on ngOnDestroy method of your component.

remember to import {OnDestroy} from '@angular/core' and add OnDestroy to the implements section of your Class definition

Hope this helps.
