Angular question: I would love to know how to make use of a service in a controller, if the service is stored in..

A separate file.

Let's say I have this code, how would I need to alter my controller file, in order to make use of the service if it was not chained directly on the controller, but stored in a folder, named services, and that service was in its own file named "honingService".

angular.module('HoningNow', [])
.controller('HoningnowController', function ($scope, honingService) {
    $scope.honingNow = honingService.honingNow;


})

.service('honingService' function () {
this.honingNow = [

       {
          { "name" : "Yeoman" },
          { "name" : "Sass" },
          { "name" : "D3" },
          { "name" : "Browserfiy" },
          { "name" : "Protractor" },

       }


    ];

});

Your original file would look like this:

angular.module('HoningNow', [])
.controller('HoningnowController', function ($scope, honingService) {

    $scope.honingNow = honingService.honingNow;


});

And your new file like this:

angular.module('HoningNow').service('honingService' function () {
this.honingNow = [
       {
          { "name" : "Yeoman" },
          { "name" : "Sass" },
          { "name" : "D3" },
          { "name" : "Browserfiy" },
          { "name" : "Protractor" },
       }
    ];
});

the only difference here is that in the new file you use angular.module again but this time without the second parameter, dependencies. This way you tell angular to use that existing module and add your new service to it. Obviously you can't use method chainig like this: angular.module('module', []).controller().service() because your code is in two files now.

Now however you need to include both files in your index.html <head> tag
