title: Facebook login for mobile clients with Node express backend
body: <p>I'm using <a href="https://www.npmjs.com/package/parse-server" rel="nofollow">parse-server</a> (on heroku) as the backend for a mobile app.</p>
  
  <p>Facebook login/signup will be an option for users. </p>
  
  <p>What's the best workflow?</p>
  
  <ol>
  <li>I was thinking the mobile client could login to FB and pass the token to the express app.  The express app could grab the data we need from FB and create/login the Parse user.</li>
  </ol>
  
  <p>Is there a module where I can plug in the auth token and ping FB for the profile picture, DOB, or whatever else I need? </p>
  
  <ol start="2">
  <li>Parse JS SDK has a <a href="https://parse.com/docs/js/api/classes/Parse.FacebookUtils.html" rel="nofollow">facebookUtils</a> API.  Can I create a route that the mobile apps can hit in a browser to login to FB?  If so how can I get the data I need from FB once they've logged in?</li>
  </ol>
  
  <p>Any insight and sample code would be MUCH appreciated.</p>
  
  <p>Thanks!</p>
