Best way to invoke Rest APIs from angularjs?

Question

From where should REST API request be invoked from angular js?

I.e. from controller, module, service, factory. I am totally confused that what should be the right w

Answer 1

This is how we do this, Write the http service as a factory method.

Edited as per comments to use Promise API

 var MyApp = angular.module('App', []);

 MyApp .factory('ApiFactory', ['$http',
        function ($http) {
            return {
               getUsers: function (rowcount) {
                var promise = $http.get('api/Users/' + rowcount) .then(function(response) {
                return response.data;
              }, function (error) {
                //error
            })
            return promise;
           }
         }
       }
   ]);

Now you can use it in controller as this.

MyApp .controller('MyController', ['$scope', 'ApiFactory',
  function ($scope, ApiFactory) {

    $scope.Users = null;

    ApiFactory.getUsers(count).then(function(data)
    {
      $scope.Users = data;
    });
 } 
 ]);
