Nextjs Supabase Auth
sickn33/antigravity-awesome-skillsThis skill enables seamless integration of Supabase Authentication with Next.js App Router, focusing on secure handling of auth tokens, route protection, and session management. It supports various patterns like middleware, OAuth callback handling, and server actions to facilitate robust authentication workflows. Designed for developers building secure, server-rendered Next.js applications, it emphasizes best practices and safeguards to prevent common anti-patterns.
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:
- Use @supabase/ssr for App Router integration
- Handle tokens in middleware for protected routes
- Never expose auth tokens to client unnecessarily
- Use Server Actions for auth operations when possible
- 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
