title: how to auto generate Universal Angular files?
body: <p>I follow the tutorial from angular for Universal:
  <a href="https://angular.io/guide/universal" rel="nofollow noreferrer">https://angular.io/guide/universal</a></p>
  
  <p>I try to install Universal with:</p>
  
  <pre><code>ng add @nguniversal/express-engine --clientProject angular.io-example
  </code></pre>
  
  <p>Well, the code running fine doesn't return any error. But it doesn't generate any of following files like it suppose to:</p>
  
  <pre><code>main.server.ts
  tsconfig.server.json      
  app.server.module.ts    
  server.ts                    
  webpack.server.config.js
  </code></pre>
  
  <p>Here is package.json:</p>

  <p>So, is the documentation missing something? or am I missing something?</p>
