title: Retrieving JSON from firebase storage
body: <p>I am using D3js to parse some information and would like the JSON to be stored online rather than locally. I am pulling the JSON from firebase doing the following:</p>
  
  <pre><code> var storageRef = firebase.storage().ref().child("main_bubble.json");
  storageRef.getDownloadURL().then(function(url) {
    console.log(url);
  });
  </code></pre>
  
  <p>it returns the URL properly, but how do I convert it into JSON?</p>
