title: Develop Angular App in Sub-Directory
body: <p><strong>Is there any way I can configure the <code>ng-serve</code> command to serve static html files at the root directory, and serve an angular app at a sub-directory?</strong></p>
  
  <hr>
  
  <p>I'm developing an angular 2 app, and for SEO reasons I want to host the actual app in a sub directory while serving static pages from the root directory. Something like this</p>
  
  <pre><code>./
      About.html
      Home.html
      Contact.html
      /app
         app.html //Angular app goes here
  </code></pre>
  
  <p>I've found the <code>ng build --base-href &lt;base&gt;</code> which creates a production version of the angular app that can live in the <code>&lt;base&gt;</code> sub-directory, but this means I have to develop the angular app separately and then import the output into my final project. I'm hoping for an angualr-cli solution, but I'm open to any ideas.</p>
