Catch verification error.

[uwejan]

Perhaps i miss read, forgive me. but i could not find anything related to how to catch verification error.
i notice jsonwebtoken has this method,

jwt.verify(token, 'shhhhh', function(err, decoded) {
  if (err) {
    /*
      err = {
        name: 'TokenExpiredError',
        message: 'jwt expired',
        expiredAt: 1408621000
      }
    */
  }
});

Purpose make a redis call to invalidate session.
Thanks.

@uwejan if you can give us a bit more context/detail we might be able to help. Thanks.

Hi, Thanks for looking at this.
What i mean, is the same way how we have the verify method to invoke our own verification and return isValid:true.
in case the token expired, i want to delete a session that i created on the verify method. so maybe token expired custom method like verify method to give more flexibility.
