Body

I was not able to find a complete tutorial about authentication and authorization using NextJS 16, latest Auth version, and proxy file.

It doesn't necessarily have to be a video, can also be written. Thanks!

At the moment, complete end-to-end tutorials specifically covering Next.js 16 + latest Auth.js + proxy setup are still limited, mainly because both Next.js 16 features and the newest Auth.js changes are relatively recent.

However, you can combine the official documentation with a few focused guides to cover the full flow of authentication and authorization.

Recommended resources:

1. Auth.js (NextAuth) official documentation
   Covers setup, providers, session handling, middleware, and role-based authorization.
   https://authjs.dev/

2. Next.js documentation – Authentication
   Explains how authentication works with App Router, middleware, and server components.
   https://nextjs.org/docs/app/building-your-application/authentication

3. Auth.js GitHub examples repository
   Contains working examples for different setups, including App Router patterns.
   https://github.com/nextauthjs/next-auth-example

4. Proxy / middleware approach
   In Next.js 16, authorization logic is often handled in middleware (or proxy layer) to protect routes before rendering. Searching for:
   "Auth.js middleware example App Router"
   "Next.js middleware role based auth"
   can help locate updated patterns.

General flow (high level):
• Configure Auth.js with providers (Google, GitHub, credentials, etc.)
• Store session using JWT or database adapter
• Protect routes using middleware/proxy checks
• Access session in server components or client components
• Implement role-based authorization if needed

Because the ecosystem is evolving quickly, checking GitHub discussions and official example repos often provides more up-to-date patterns than standalone tutorials.

If helpful, searching specifically for:
"Auth.js v5 App Router example"
or
"Next.js App Router authentication middleware example"
usually yields the most relevant and current guides.

Thanks a lot for the summary! I will take it from there.
