title: Save Token in local Storage using node
body: <p>I'm using JWT <code>("jsonwebtoken": "^5.4.0")</code> with express 4 and jade.
  I'm able to create the right Token, but How can i Pass this token in each call?
  Where I have to store this token ? in headers or in localStorage?</p>
  
  <p>For now I'm using CURL with Postman, and Set token in header in</p>
  
  <pre><code>x-access-token
  </code></pre>
  
  <p>Have I Do create a middleware that retrieve a token from Database and use this in each call?</p>
  
  <p>thanks</p>
