What problem does it solve?

This Skill streamlines secure authentication in Next.js applications by integrating Supabase Auth across both server and client boundaries, simplifying protected routes and session management.

Core Features & Use Cases

  • Seamless integration of Supabase Auth with the Next.js App Router for both server and client components
  • Middleware-based route protection, token handling, and cookie-based sessions
  • Server Actions and OAuth callback support for secure login flows and session refresh
  • Use Case: Protect an admin dashboard and tailor content based on user roles

Quick Start

Install and configure the Supabase client and auth helpers for a Next.js App Router project, then enable middleware protection for routes and implement login/logout flows.

FAQPage Schema
How do I set up Supabase Auth with the Next.js App Router?

Supabase Auth integrates with the Next.js App Router by configuring the @supabase/ssr client to manage cookie-based sessions across server and client components. This setup enables protected routes, middleware token handling, and secure OAuth callbacks.

How does middleware handle session management for Supabase Auth?

Middleware handles Supabase Auth session management by intercepting requests to refresh tokens and validate cookies before route access. This approach secures protected routes using cookie-based sessions without exposing sensitive authentication tokens.

Can I use server actions for login and logout flows in Next.js?

Yes, you can use Next.js server actions for Supabase Auth login and logout flows. Server actions securely process authentication tasks on the server, managing cookie-based sessions and handling OAuth callbacks for protected applications.

What is the best way to protect an admin dashboard in Next.js using Supabase?

Protecting a Next.js admin dashboard with Supabase involves applying middleware-based route protection and validating user roles via cookie-based sessions. This ensures only authorized users access secure areas while tailoring content based on role data.

Do I need the @supabase/ssr client for Next.js authentication?

Yes, the @supabase/ssr client is required for Next.js App Router authentication. It bridges the server and client boundary, enabling secure cookie-based session management, middleware token handling, and OAuth callback processing.

Why are my Supabase Auth sessions not persisting across Next.js server and client components?

Sessions fail to persist across Next.js components when cookie-based session handling is misconfigured. Using the @supabase/ssr client ensures proper token refresh and session synchronization across the server and client boundary.
