Processing $http response in service

Question

I recently posted a detailed description of the issue I am facing here at SO. As I couldn\'t send an actual $http request, I used timeout to simulate asynchrono

tosh shimayama have a solution but you can simplify a lot if you use the fact that $http returns promises and that promises can return a value:

app.factory('myService', function($http, $q) {
  myService.async = function() {
    return $http.get('test.json')
    .then(function (response) {
      var data = reponse.data;
      console.log(data);
      return data;
    });
  };

  return myService;
});

app.controller('MainCtrl', function( myService,$scope) {
  $scope.asyncData = myService.async();
  $scope.$watch('asyncData', function(asyncData) {
    if(angular.isDefined(asyncData)) {
      // Do something with the returned data, angular handle promises fine, you don't have to reassign the value to the scope if you just want to use it with angular directives
    }
  });

});
