title: how to refresh token when expired in jwt
body: <p>I am implementing JWT in my project. I implemented jwt and gave it an expiration time of 1 minute. The jwt that is generated from the api side is during login and the token and expiration details are sent in the result and are stored in local storage. How can I refresh the expired token from API side and send it back again to the client so that it can be stored in local storage and sent for every call using interceptor?</p>
  
  <p>this is how I created jwt and gave expiration time</p>
  
  <pre><code>// let us suppose this is my input
  tokenObject = { User: { username: name, pwd: pwd } };
  //creating a jwt here
  jwt.sign({ tokenObject }, "secretkey", { expiresIn: "60s" }, (err, token) =&gt; {
    res.json({
      token
    });
  });
  </code></pre>
  
  <p>After this, I'm verifying the token in the result and sending it in result to the client.
  After a minute how do I regenerate the token?
  Please help and let me know the way and tell me if I am doing something wrong . Thanks!!</p>
