gistfile1.js

/**
 * WAY 1: ANGULARJS TUTORIAL
 */ 

// app.js
var myApp = angular.module('myApp',[]);


// controllers/greeting.js
myApp.controller('GreetingCtrl', ['$scope', function($scope) {
    $scope.greeting = 'Hola!';
}]);




/**
 * WAY 2: THINKSTER.IO FANTASY FOOTBALL
 */ 

//app.js
window.app = angular.module('ngFantasyFootball', [
    'ngCookies', 'ngResource', 'ui.bootstrap', 'ngRoute', 'ngff.controllers', 'ngff.directives', 'ngff.services'
]);

window.angular.module('ngff.controllers', [
  'ngff.controllers.header',
  'ngff.controllers.index',
  'ngff.controllers.nfl',
  'ngff.controllers.leagues',
  'ngff.controllers.fantasyteams'
]);

window.angular.module('ngff.services', [
  'ngff.services.global',
  'ngff.services.nfl',
  'ngff.services.leagues',
  'ngff.services.fantasyteams'
]);

// controllers/fantasyteams.js
window.angular.module('ngff.controllers.fantasyteams', [])
  .controller('FantasyTeamsController', ['$scope', '$routeParams', '$location', 'Global', 'Leagues', 'FantasyTeams',
    function ($scope, $routeParams, $location, Global, Leagues, FantasyTeams) {

      $scope.global = Global;

      $scope.populateLeagues = function (query) {
        Leagues.query(query, function (leagues) {
          $scope.leagues = leagues;
        })
      };

    }]);
