Integrating native JavaScript classes in an Angular app

Question

I have a native JavaScript class:

var Holder = new function(elements) {

    this.elements = elements;

    this.any         


        

Answer 1

As I understand it, a factory is a singleton, but a factory can generate a class that can create instances. So the factory would return a reference to the constructor when you inject it, or a wrapper function around the constructor to use it without using new:

.factory('Holder', function() {
  function Holder(elements) {
    this.elements = elements; 
  }
  Holder.prototype.get = function() {
    return this.elements;
  };
  return function(elements) {
    return new Holder(elements);
  };
})

.controller('Main', function($scope, Holder) {
  var elements = [
    {id: 1, label: 'foo'},
    {id: 2, label: 'bar'}
  ];
  $scope.elements = Holder(elements).get();
});
