Loading and no items indication for angular

gistfile1.html

<!-- This assumes you are using ngResource to request data (http://docs.angularjs.org/api/ngResource.$resource) -->

<ul>
  <!--
    We can use ng-show="{expression}" to programmatically display something.
    
    ngResouce adds a handy $resolved property to your data objects.
    So, let's key off of that to indicate loading
  -->
  <li ng-show="!things.$resolved">Loading...</li>
  <!-- 
    If $resolved is true, the request has returned.
    So, $resolved being true, let's make sure we have models
  -->
  <li ng-show="things.$resolved && things.length === 0">No things</li>
  <!-- Finally, use the angular repeater to build the list of model views -->
  <li ng-repeat="thing in things">{{ thing }}</li>
</ul>
