title: angular 2 lazy loading of chunks with webpack
body: <p>I have a simple angular2-cli project which uses webpack and I want to use the angular lazy loading feature to load modules.
  The following works fine:</p>
  
  <pre><code>  {
      path: 'users',
      loadChildren: 'app/users/users.module#UsersModule',
    },
  </code></pre>
  
  <p>This code will bundle the users module as 0.chunk.js. For reasons like simplification I want load this chunk file directly, like:</p>
  
  <pre><code>  {
      path: 'users',
      loadChildren: () =&gt; require("&lt;...path&gt;/0.chunk.js")
    },
  </code></pre>
  
  <p>But it I open the page it results in the error message</p>
  
  <pre><code>core.es5.js:1084 ERROR Error: Uncaught (in promise): **Error: No NgModule metadata found for '[object Object]'.**
  Error: No NgModule metadata found for '[object Object]'.

  </code></pre>
  
  <p>Now my question: How is it possible?</p>
  
  <p>Thank you very much!</p>
