nextjs-supabase-auth

To integrate Supabase authentication with Next.js App Router, use @supabase/ssr to manage secure token handling in middleware, protect routes, and perform auth operations via server actions across server and client components.

The best way to protect routes using Supabase middleware in Next.js is to implement middleware-based route protection and session management that securely handles authentication tokens across the server and client boundary.

Yes, @supabase/ssr works with Next.js server components and server actions by providing patterns for secure token handling and executing auth operations directly within the App Router architecture.

To handle OAuth callbacks in Next.js App Router with Supabase, apply authentication patterns that process OAuth callback routes and securely manage session tokens within your server and client components.

Supabase auth sessions break between Next.js client and server components when token handling is not securely managed across the boundary; using @supabase/ssr in middleware ensures consistent session management and token refresh.
