How to "decorate the response with authentication headers" in responseFunc

[przemyslaw-wlodek]

I'm sorry, but I'm new to HapiJS, and I don't truly understand how responseFunc works.
I want to return new token in every response, so I created a function:

function refreshSession(request, reply) {
  const { response } = request;
  const { exp, userId } = request.auth.credentials;

  // if token has expiry date then create and send new session token with each request

  if (exp) {
    response.header('Authorization', session.create(userId));
  }

  reply.continue(); // < --- is it correct?
}

Documentation says: reply(err, response) - is called if an error occurred.
So I've tried many variations with passing arguments to reply, but it never worked properly.

I'm asking to be sure if above is right or it if has some hidden pitfalls.

Thanks in advance.

@xgarrett are you returning a new token on each response for security reasons?

No. I'm doing it when user doesn't want to have "infinite" session. Then session token stays valid for ~2hours, I'm returning new to maintain 2h from last request.
