title: How to add prefix to all node / express routes
body: <p>Does anyone know of a way to configure express to add a prefix before all routes automatically? for example, currently I have:</p>
  
  <p><code>/</code></p>
  
  <p><code>/route1</code></p>
  
  <p><code>/route2</code></p>
  
  <p>However, I want to add a prefix like:</p>
  
  <p><code>/prefix/</code></p>
  
  <p><code>/prefix/route1</code></p>
  
  <p><code>/prefix/route2</code></p>
  
  <p>Right now I need to define <code>prefix</code> manually to all of my routes but would like a more automated/configurable way. Can someone help?</p>
  
  <p>Thanks in advance!</p>
