Leveraging the Next-Auth JWT for enhancing the security of my server

As I begin setting up my next.js app, I am considering using next-auth's JWT strategy for authentication. While I understand how this can protect routes and API endpoints within the API folder of Next.js, I also have a separate express.js server responsible for handling API calls to my database.

My main question is whether there is a way to transmit the JWT token to my express server along with API requests, and store the secret on that server in order to authenticate sessions and grant users access to the API routes.

I was thinking about either integrating this process into a next-auth callback or simply sending the JWT token when necessary. However, I encountered difficulties trying to view the complete JWT server-side as all server-side hooks provided by next-auth only extract data from the token.

Any insights on this matter would be greatly appreciated. Thank you.

Answer №1

Achieving this desired outcome is definitely possible by utilizing the CredentialsProvider. Simply make a call to your login endpoint to obtain the JWT tokens once the user has successfully logged in. These tokens can then be stored in the next-auth session, allowing for easy access using the useSession() function from any part of your application. This way, you will have the necessary token to include with any REQUEST sent to your backend server.
