How to Update User Session in Next.js with Auth0 Without Logging Out

Managing user sessions in a web application can be tricky, especially when dealing with user metadata updates. If you're using Next.js combined with Auth0 for authentication and are looking to update a user's session after modifying their metadata without logging them out, you're in the right place. In this guide, we will tackle this problem head-on and walk you through a practical solution.

The Problem at Hand: Updating User Metadata

Imagine a situation where your application allows users to save their favorite items. When they select an object to mark as a favorite, you need to update their user metadata stored in Auth0. Ideally, you want these changes to reflect immediately in the user's session without requiring them to log out and back in.

However, you might run into an issue where changes to the user metadata only take effect after logging out and logging in again. This is less than ideal for user experience, and that’s where we need a workaround.

Step-by-Step Solution

Let’s break down the solution into several organized sections to ensure clarity and ease of understanding.

1. Update Metadata in the API

First, you have your API handler in api/updateMetadata.ts which is responsible for handling the update request. This is how it typically looks:

Adding await updateSession(req, res, { ...session, user }); ensures that the session is updated immediately after modifying the user metadata.

2. Fetch Updated Session in the Client

On the client side, leverage the checkSession function from useUser to refresh the session data after making the update:

3. Modify Profile Handler in Auth0

Lastly, to ensure that the user profile is refreshed properly when using the built-in Auth0 methods, you need to adjust the profile handler in pages/api/auth/[...auth0].tsx as follows:

Conclusion

By implementing these adjustments, you can effectively refresh user metadata in a Next.js application using Auth0 without forcing a logout. This greatly enhances the user experience and keeps the data consistent across your application.
