title: How to use JWT Token at Heroku
body: <p>I am using the Heroku to up my back-end. At my back-end, I have one route that it is to log in to the application. So when I log at my application, it is created the <code>JWT TOKEN</code> in this format.</p>
  
  <pre><code>"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwiZW1haWwiOiJ0ZXN0ZUBnbWFpbC5jb20iLCJ0eXBlIjoiZmlzIiwiaWF0IjoxNTkwMTU3NzA4fQ.dpGRBog-KfVqd4PknxeLmjNCfT1zBodscJ6OO9Fg8do
  </code></pre>
  
  <p>Some routes at my application need to check if the user are logged, verify one function that I have called <code>passport.authenticate()</code> it is a middleware. And I would like to know how can I use to heroku to test my application.</p>
