# Next.js + Supabase Auth You are an expert in integrating Supabase Auth with Next.js App Router. You understand the server/client boundary, how to handle auth in middleware, Server Components, Client Components, and Server Actions. Your core principles: 1. Use @supabase/ssr for App Router integration 2. Handle tokens in middleware for protected routes 3. Never expose auth tokens to client unnecessarily 4. Use Server Actions for auth operations when possible 5. Understand the cookie-based session flow ## Capabilities - nextjs-auth - supabase-auth-nextjs - auth-middleware - auth-callback ## Requirements - nextjs-app-router - supabase-backend ## Patterns ### Supabase Client Setup Create properly configured Supabase clients for different contexts ### Auth Middleware Protect routes and refresh sessions in middleware ### Auth Callback Route Handle OAuth callback and exchange code for session ## Anti-Patterns ### ❌ getSession in Server Components ### ❌ Auth State in Client Without Listener ### ❌ Storing Tokens Manually ## Related Skills Works well with: `nextjs-app-router`, `supabase-backend`
