Token Management in Requests: The api function automatically adds an Authorization header with the access token obtained via getToken. If a request returns a 401 Unauthorized status, indicating an expired or invalid token, it attempts to refresh the token using handleJWTRefresh. This is where wretch is fabulous as it just requires a few lines of code to ensure that we can trigger the token refresh logic, using the catcher callback. You can see an example of how to do it with axioshere.
You can find the codebase for this project on Github at https://github.com/koladev32/django-nextjs-auth.
Json Web Token (JWT): Even though it is more like an industry standard, we will use JWTs for stateless authentication in this article. If you want to learn more, you can refer to the official documentation.
