SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you implement secure Supabase authentication in Next.js App Router without leaking tokens or breaking the server/client boundary.

Core Features & Use Cases

  • App Router Integration: Set up Supabase clients correctly for Server Components, Client Components, middleware, and Server Actions.
  • Protected Routes: Refresh sessions and guard authenticated pages with middleware-based token handling.
  • OAuth Callback Flows: Exchange auth codes for sessions and complete sign-in redirects cleanly.
  • Use Case: Build a Next.js app with login, logout, and protected dashboard routes backed by Supabase Auth.

Quick Start

Ask for a secure Supabase Auth setup for a Next.js App Router app with middleware, OAuth callback handling, and server-side session management.

FAQPage Schema
How do I set up Supabase authentication in Next.js App Router?▼

Supabase authentication in Next.js App Router requires configuring @supabase/ssr clients for Server Components, Client Components, and Server Actions. This setup uses cookie-based session management to maintain secure server and client boundaries across your application.

How does OAuth callback handling work with Supabase in Next.js?▼

OAuth callback handling in Next.js with Supabase exchanges auth codes for sessions and completes sign-in redirects cleanly. This process ensures secure token exchange and proper redirection after user authentication.

What is the best way to manage Supabase sessions in Next.js Server Actions?▼

Managing Supabase sessions in Next.js Server Actions involves using @supabase/ssr patterns with cookie-based session flows. This ensures secure server-side session validation without leaking tokens across the server and client boundary.

Why does my Supabase session break across Next.js Server and Client Components?▼

Supabase sessions break across Next.js boundaries when server and client clients are configured incorrectly. Using @supabase/ssr patterns with proper cookie-based session management prevents token leaks and maintains consistent authentication state.
