Example "Collection" implementation for angularFire

myController.js

function MyController($scope, $firebaseCollection) {
  
  // "images" - contains for example >10 000 children and we don't want to fetch them all at once
  var imagesRef = new Firebase("https://<my-firebase>.firebaseio.com/images");

  // Creates an empty collection for images
  // Collection should now track changes in imagesRef.
  // Example methods:
  // $push( snapshot ) - Push new children to collection
  $scope.images = $firebaseCollection(imagesRef);

  // We have a view with a list of images. We only want to fetch 100 latest images.
  imagesRef.limit(100).once('value', function(snapshot) {
    // Push fetched images to our collection.
    
    $scope.images.$push(snapshot);
    // Now for example if a child is removed from "imagesRef" and it matches to one we just pushed to our collection,
    // the collection removes it automatically from itself.
    // It also tracks all changes to pushed images and updates the data automatically.
  });
