How to refactor angular dependency injection for concatination and minification?

I have written my angular application into seperate files for my readability and ways to easily find things to edit/code. This is my app.js that requires the dependencies.

app.js

var app = angular.module('app', ['ngResource', 'ngRoute', 'app.services', 'app.controllers', 'app.feed','app.directives', 'app.factories']);

app.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
    ...
}]);

This is an example of how the dependencies are written out.

services.js

var app = angular.module('app.services', []);

app.factory('AuthService', ['$scope'], function($scope) {
    ...
}]);

However, when I try to concat the scripts, app is redefined constantly. I thought of taking out the var declaration but, I like to keep the files separate.

How would I be able to write this out where the dependency injections stay intact for my app.js, while still keeping the files separate.

To prevent the constant re declaration of you app variable, you can take advantage of the module pattern: Angular Style Guide:Modules. Instead of explicitly declaring app in every dependency:

var app = angular.module('app.services', []);

app.factory('AuthService', ['$scope'], function($scope) {
    ...
}]);

You can define you service, component, directive, controller, etc as a part of the correct module: 

angular.module('app.services')
.factory('AuthService', ['$scope'], function($scope) {
    ...
}]);

Declaring an 'app.services' module would only need to happen once.

See : Angular Style Guide:Modules for better explanations.
