Run Code When Leaving Your Angular Application
summary
Claims that ngOnDestroy not fired on refresh or tab close, demonstrates that Angular doesn’t destroy components on browser refresh so the lifecycle hook is skipped, and shows a working fix: add a @HostListener('window:beforeunload', ['$event']) method that logs the event. The demo runs in the browser, the console shows the beforeunload handler firing, and the talk gives concrete uses like clearing local/session storage or logging users out which are proved to work.
