AngularJS : How to watch service variables?

Question

I have a service, say:

factory(\'aService\', [\'$rootScope\', \'$resource\', function ($rootScope, $resource) {
  var service = {
    foo: []
  };

  return          


        

Answer 1

I am late to the part but I found a nicer way to do this than the answer posted above. Instead of assigning a variable to hold the value of the service variable, I created a function attached to the scope, that returns the service variable.

controller

$scope.foo = function(){
 return aService.foo;
}

I think this will do what you want. My controller keeps checking the value of my service with this implementation. Honestly, this is much simpler than the selected answer.
