Angular2 spinner for ngFor

Question

I have ngForwith a lot of elements that are displayed, and I want to show the spinner while the elements are not only loading, but also being displayed.

I know how I can display the counter when loading items from the server (i.e. observables), but this takes a little time in my case. I see that most of the time is spent on a browser displaying all the elements ngFor, and I don’t know how to make sure that the counter is still displayed for this process. I tried the ngAfterViewCheckedlifecycle hook , but it also fires to completion ngFor.

So, I wonder if there is a way to connect to this process? Alternatively, can we get Angular2 / browser to display elements ngForin stages? That is, show the elements as they are displayed, and show them all immediately after creating the templates.

I am using Angular 2.0.0. Any help was appreciated.
