How to execute some code before closing browser?

Question

I want to execute localStorage.clear() before I close my browser. I have tried this:

export class AppComponent {

    @HostListener("window:onbeforeunload",["$event"])
        clearLocalStorage(event){
        localStorage.clear();
    }
}

But no results. Any ideas ?

Make your AppComponent implements OnDestroy interface.

export class AppComponent implements OnDestroy{

    ngOnDestroy() {
        localStorage.clear();
    }
}
