Step-1: Create JavaScript localStorage and save a token. localStorage saves a token as key value pair. It has no expiry time. It will available when we open new tab, too.
Set Item code:
localStorage.setItem("token_name", "username");
Get Item code:
var username= localStorage.getItem("token_name");
Step-2: Once you logout, remove the value from localStorage.
localStorage.removeItem("token_name");
Step-3: Use storage event. It will be fired automatically in all tabs when localStorage will be modified.
@Component({
------
})
export class AppComponent implements OnInit{
ngOnInit() {
window.addEventListener('storage', (event) => {
if (event.storageArea == localStorage) {
let token = localStorage.getItem('token_name');
if(token == undefined) {
// Perform logout
//Navigate to login/home
this.router.navigate(['/login']);
}
}
});
}
}
