title: How can I point upper folder when using express.static() in Express 4.0?
body: <p>My angular &amp; node app structure is like this. </p>
  
  <pre><code>MyApp/
  ----app/
  --------components/
  -----------angular js files(js,css)
  ----server/
  --------server.js
  ----index.html
  </code></pre>
  
  <p>And I want to use  <code>express.static()</code> to set static files such as angular.js files or css files. but, I'm not sure how to point to upper folder when using <code>static(__dirname +'/app')</code>.</p>
  
  <p><code>__dirname</code> means current directory but I want to point upper directory.</p>
