Approach for AngularJS app settings

app.settings.js

angular.app('testing', [])
    .constant(‘baseSettings’, {})
    .value('appSettings', {})
    .controller('MainCtrl', function($scope, appSettings){
        $scope.$watch(function(){ return appSettings; }, function(old, _new){
            //your code here…
        });
    })
    .controller('AnotherCtrl', function($scope , SettingsHelper){
        SettingsHelper.setSetting('enableToPerform', true);
    })
    .factory('SettingsHelper', function(baseSettings, appSettings){
        function getSetting(setting){ return appSettings[setting]; }
        function setSetting(setting, value){ appSettings[setting] = value; }
        function resetSettings(){ appSettings = baseSettings; }
        return {
            getSetting: getSetting,
            setSetting: setSetting,
            resetSettings: resetSettings
        };
    })
    .service('SomeService', function(SettingHelper){
        this.someMethod = function() {
            if(SettingHelper.getSetting('enableToPerform')){
                //do it!
            }
        }
    });
