title: nodejs - How to deal with an API which returns circular structure JSON
body: <p>I am using the Zoopla developer API to get some historical pricing data.</p>
  
  <p>My http get method is as follows</p>
  
  <pre><code>http.get(url, function(err, data) {
    if (err) console.log(err);
    res.send(data);
  });
  </code></pre>
