Angular 5 - Clear localStorage when browser is closed












0















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.
