gistfile1.js

angular.module('App', ['ngRoute'])
  .run(function(repositories) {
    //ensure that request is sent on application start, you could also
    //call load() on route.resolve() depending on your needs
    repositories.load();
  })
  .config(function($routeProvider) {
    $routeProvider
      .when('/', {
        resolve: {
          // route will wait for promise to be resolved before render
          github: function(repositories) {
            //could be: return repositories.load()
            return repositories.promise;
          }
        }
      })
  });

angular.module('App').service('repositories', function($http) {
  
  var promise;
