title: How to pipe response from request in Express.js?
body: <p>So i use <code>request</code> library to get an URL. I would like to pipe it to a <code>response</code> in Express but I haven't figured it out how to do it.</p>
  
  <pre><code>function routeHandler(req, res) {
  ...
  request.getAsync(theUrl)
      .spread(function(response,body) {
          // how to pipe it to res here?
      })
  </code></pre>
