How to automatically renew access token jwt via refresh token?

Question

JSON Web Token

Please tell me how to automatically update access token jwt through refresh token. I understand that there is a separate route for updating the access token, but there will be no button in the frontend: the access token has expired, click on the button to update. So how to automatically update?

Answer 1

In Axios request interceptor, or in any other request interceptor, add a check for the term of the token, and if it has expired, then make a request for refresh, and after updating the token, continue executing the original request.
