title: Passport.js: passport-facebook-token strategy, login through JS SDK and THEN authenticate passport?
body: <p>I was looking for a way to let my client authorize with the facebook JS SDK and then somehow transfer this authorization to my node server (so it can verify requests with the fb graph api)</p>
  
  <p>I stumbled across:
  <a href="https://github.com/jaredhanson/passport-facebook/issues/26" rel="noreferrer">https://github.com/jaredhanson/passport-facebook/issues/26</a></p>
  
  <p>&amp;</p>
  
  <p><a href="https://github.com/drudge/passport-facebook-token" rel="noreferrer">https://github.com/drudge/passport-facebook-token</a></p>
  
  <p>what seems to be an entirely different strategy from passport-facebook.</p>
  
  <p>Am I correct when assuming that: </p>
  
  <p>One logs in with the fb JS SDK, and then the facebook-token strategy somehow extracts the token and fb id from the document or body object?</p>
  
  <p>Or is there any other decent way to achieve this? I'm namely trying to avoid the redirects enforced by the server SDKs</p>
