What is the best way to handle multiple promises when loading a state in Angular?

When loading the /home state, I need to retrieve all users from the database in order to customize the home controller and view based on the logged-in user. Currently, in the :resolve section of the state configuration, I am fetching all 'posts' from the database. However, I am facing difficulty implementing multiple promises at once.

Below is my code for the /home state:


$stateProvider
.state('home', {
  url: '/home',
  templateUrl: '/home.html',
  controller: 'MainCtrl',
  resolve: {
    postPromise: ['posts', function(posts){
      return posts.getAll();
      // I want to include another promise here as well.
    }]
  }
}) 

Essentially, I would like to execute a users.getAll() function within the resolve of the /home state but I am struggling with the syntax to accomplish this task.

To enhance your state configuration, simply include a second resolve:

$stateProvider
.state('home', {
  url: '/home',
  templateUrl: '/home.html',
  controller: 'MainCtrl',
  resolve: {
    postPromise: ['posts', function(posts){
      return posts.getAll();
      // This code resolves more than one promise at a time.  
    }],
    userPromise: ['users', function(users){
      return users.getAll();
    }]
  }
}) 

Alternatively, you can use $q.all([userPromise, postsPromise]): this will combine multiple promises into one, which will be resolved once all promises in the array are resolved. The result will be an array containing the values of each individual promise.
