Simple flag is the first thing that comes to my mind.

<component *ngIf="!isLoading">...</component>‍
<progress-spinner *ngIf="isLoading"></progress-spinner>‍‍‍‍‍

And set this flag once you finished loading your data

this.isLoading = true;

someMethod().subscribe(() => {
  // do some other stuff
  this.isLoading = false
});‍‍‍‍‍‍

In this case you delay showing the list and display some progress spinner at the same time

If not, how to bind component with 'isLoading' property?
