Angular 5 - Clear localStorage when browser is closed
I am using Angular 5 for my web application. I want to clear the localStorage objects, whenever the user closes the browser window.
@HostListener("window:beforeunload", ["$event"])
clearLocalStorage(event) {
localStorage.clear();
console.log('####Destroy local storage####');
}
I cannot stick the above code in the main app.component.ts due to other logics such as SSO in the application.
Is there a way, i can perform this action globally in the angular app with different approach.
Please suggest.

Local storage is not a good option in your case.
Local Storage - Stores data with no expiration date, and gets cleared only through JavaScript, or clearing the Browser cache / Locally Stored Data.
While the Session Storage - stores data only for a session, meaning that the data is stored until the browser (or tab) is closed.
So use Session Storage for your purpose. It will be cleared automatically on browser closing.

You can use sessionStorage instead.
Session Storage
If you using the approach you mentioned. If you open 2 tabs at the same time, when you close one tab, the localStorage will be cleared.
localStorage will be cleared.....you mean sessionStorage.
