title: Retrieving json file from Firebase Storage
body: <p>I would like to be able to get a json file from Firebase Storage to work with. I don't need to push it back.</p>
  
  <p>Does Firebase Storage can give me that and if so, how can I do it with Angular?</p>
  
  <p>If not, does the Firebase database is a better choice?</p>
  
  <p>I already downloaded firebase and angularfire2.</p>
  
  <p>I tried getDownloadURL and getMetadata, but don't know how to get the info inside.</p>
  
  <p>Thanks for your help! </p>
