title: How to get intellisense for express.js in vscode
body: <p>I have tried installing type definitions with:</p>
  
  <p>My code is in <strong><code>server.js</code></strong> javascript file.</p>
  
  <p><strong><code>npm install @types/express</code></strong></p>
  
  <p>But still it doesn't seem to give intellisense for app after instantiating express .</p>
  
  <p>But when I use express like this :</p>
  
  <pre><code>app = express() ;
  
  app.listen(8000) ;
  </code></pre>
  
  <h3>I am not getting the codecompletion or intellisense for app instance of express.</h3>
  
  <p>How to fix this ? </p>
