Current behavior

Is possible to see a loader in the components when the data are loaded from LocalStorage?

I use this to load the number of total item in cart this.cartService.itemCount() but while the data are taken from LocalStorage i see nothing. Is possibile to show a loader or a placeholder in this fraction of time?

Data loaded from localStorage is really fast. Check:

There is no point in adding a loader for this operation because the loader will never be visible on the screen.
