title: Passport & JWT & Google Strategy - Disable session & res.send() after google callback
body: <p>Using: <a href="https://github.com/mstade/passport-google-oauth2" rel="noreferrer">passport-google-oauth2</a>.</p>
  
  <p>I want to use <a href="https://github.com/auth0/node-jsonwebtoken" rel="noreferrer">JWT</a> with Google login - for that I need to <a href="https://stackoverflow.com/questions/20228572/passport-local-with-node-jwt-simple">disable session</a> and somehow pass the user model back to client.
  All the examples are using google callback that <a href="https://github.com/mstade/passport-google-oauth2#authenticate-requests" rel="noreferrer">magically redirect to '/'</a>.<br><br>
  How do I:<br>
  1. Disable session while using passport-google-oauth2.<br>
  2. res.send() user to client after google authentication.</p>
  
  <p>Feel free to suggest alternatives if I'm not on the right direction.</p>
