Refresh Token Jsonwebtoken

Question

I am using jsonwebtoken in NodeJs API application for authenticating user in my API application. The flow that I have setup is as follows:

1) The user registers through

Answer 1

I had same problem in a project.

1) I created the refresh token and returned it when user signed in (with the jsonwebtoken). I saved the refresh token with the user.

2) When client send a request with the expired token, server returns 401.

3) I implemented a new path to refresh the token. It receives the refresh token and the user as param and returns a new token (jsonwebtoken).

4) (optional) You can implement a mechanism for invalidating a refresh token, in case someone stole it

I based my implementation in this post, really good snippets:
