We’ve had such amazing response to the blog post! If you’re using Auth0 to build Next.js applications with any of the deployment models documented in this post we would love to hear your feedback and comments!

Great write-up. I’ve been tooling around with a lot of different methods, mostly the custom server, but would like to get it working serverless as described in this post. Now, while I love Auth0 and use it in pet projects, I have a requirement in a professional project to use a private OpenID Connect provider. After looking the source over a little bit, the @auth0/nextjs-auth0 library looks like it could theoretically be used for any OpenID Connect provider by providing the issuer URL, not requiring Auth0 specifically. Is that the case?
Thanks for this! I’m a bit new to auth0, does nextjs-auth0 only work with universal login? Are there examples for how to implement this using custom login/signup/password reset pages built on NextJS?
Great! I’ve been looking for a solution to run the auth server-side with next and this works well.
It looks like on the serverless example you are missing the callback handler example.

Thanks so much for the write up and work on nextjs-auth0 SDK, it’s been something really important for us at our company!
My team and I are still currently trying to figure out the best way to handle the following:
- Using the
serverlessmodel (following the NextJS example), what are your suggestions in handling re-auth / refresh? - What’s the suggested pattern for integrating this with usage of Apollo’s graphql client?
Did you get an answer this this question? I have the same question. Thanks
Sorry for that guys! Believe me I’ve pinged the repo maintainer multiple times but no response since then
I’m using auth0-nextjs to implement auth on my nextjs app using serverless api routes (no express). I’m securing api routes with requireAuthentication.
In my react-native mobile application, I’m using auth0-react-native to generate access tokens. My question is: can I use these access tokens to call the api routes set up in nextjs?? 
thank you!

Hey there @goat!
As we had difficulties contacting the repo maintainer I would suggest reaching out to him on Twitter and asking him that. Thanks!

I’ve worked with react, nextjs and worked with custom server on top of nextjs latest /api but i became more confused after reading this article. This is a hard read especially the part explaining serverless function.
Terribly sorry for the inconvenience!
Do you have any specific ideas in mind how can we make it better or is it just the fact that the concept of serverless isn’t explained in a clear way?

Great article and project!, implementation of this solution is super fast and took me almost no time.
However, I have a question (more to Auth0 and Vercel alone). is it possible to determine using a deployment on Vercel:
http: //localhost: 3000/api/auth/callback to some dynamic address so that the solution can be tested on randomly generated previews urls?
(e.g., http: //project-name-/**/.now.sh/api/auth/callback)
How can we get the user_metadata and app_metadata back from the user object?

Howdy, Nzaleski! Welcome to the Auth0 Community. Thank you for reading the blog post and raising this important question. I’ll like to research an answer for you 
Due to current times, it may take a bit longer than usual to complete that research.
On the meantime, please refer to this document that may provide you insight on what endpoints to call to get that information:
Hi Dan - I did figure out one way of retrieving the data by creating a rule to
context.idToken['http://namespace + attribube'] = user.user_metadata.attribute which brings it back to the user object. Also it looks like we can use the Management API to get the metadata as well, but I am still working on that solution.

That’s great to hear, Nzaleski! Keep me updated. When I have a cycle, I have it planned to look into this
