AngularJS : How to use one resolve for all the routes of my application

Issue

I would like to resolve the promise that loads the current user for all the pages of my application. Currently I repeat the resolve in every $routeProvider.when() of my routes.

  $routeProvider.when('/users/edit/:userId', {
  templateUrl: 'app/app/assets/partials/user-edit.html', 
  controller: 'UserEditController',
  resolve:{  
    'currentUser':function( UserService){            
        return UserService.getCurrentUser();
      }
  }
  });  

  $routeProvider.when('/staff_profil/edit', {
  templateUrl: 'app/app/assets/partials/profil-edit.html', 
  controller: 'ProfilEditController',
  resolve:{  
    'currentUser':function( UserService){            
        return UserService.getCurrentUser();
      }
  }
 });

My goal is to resolve my current user for all the routes without repetition.

Solution

You could always wrap the existing when method on the $routeProvider with your own implementation.

var myModule = angular.module('myModule', ['ngRoute'])
   .config(['$routeProvider', function($routeProvider){

      var originalWhen = $routeProvider.when;

      $routeProvider.when = function(path, route){

         route.resolve = {
            'currentUser':function( UserService){            
              return UserService.getCurrentUser();
            }
         };

         return originalWhen(path, route);
      };   

   }]);

You probably want to add some error checking in there, and use something like underscores defaults method instead of just overwriting the existing resolve property, but at least this way you can guarantee all your routes will have what you want.

It's also easy enough to wrap this up into a helper method.
