ES6 import syntax with Angular 1.5 UI Router : <p>I'm trying to combine Angular 1.5, UI Router using ES6 import modules syntax with Babel &amp; Webpack.</p>

<p>In my app.js I have:</p>

<pre><code>'use strict';

import angular from 'angular';
import uiRouter from 'angular-ui-router';
...
import LoginCtrl from './login/login.ctrl.js'


const app = angular.module("app", [
        uiRouter,
        ...
    ])
    .config(function($stateProvider, $urlRouterProvider) {
        $stateProvider
            .state('login', {
                url: '/login',
                templateUrl: '...', 
                controller: LoginCtrl,
                controllerAs: 'login' 
            })
    });
</code></pre>

<p>In login/login.ctrl.js I have:</p>

<pre><code>'use strict';

export default app.controller("LoginCtrl", function() {
    //code here
});
</code></pre>

<p>When I started my app I have following error message:</p>

<pre><code>ReferenceError: app is not defined
 bundle.js:35422:2
Error: [$injector:modulerr] Failed to instantiate module app due to:
[$injector:nomod] Module 'app' is not available! You either misspelled the module name or forgot to load it.
</code></pre>

<p>And second question. How can I use controller: "loginCtrl as login" syntax with ES6 import/export?</p>
