supabase-auth-ssr-setup

Configure Supabase SSR authentication in Next.js App Router by implementing secure cookie-based sessions, creating browser and server clients, setting environment variables, and protecting routes with middleware. This enables auth flows across server components, server actions, and the Next.js middleware layer.

Yes. Supabase SSR setup includes middleware-powered route guards that intercept requests, validate sessions from secure cookies, and redirect unauthenticated users. This protects routes at the middleware level before they reach your application.

Implement server actions that manage Supabase login and logout flows using secure session cookies and redirect logic. The pattern covers OAuth callbacks, token refresh, and session management across browser and server boundaries.

Use Supabase SSR utilities to create requireAuth and getSession helpers that retrieve current user data from secure cookies stored during authentication. These utilities work consistently across server components, server actions, and API routes.

Yes. Supabase SSR setup requires distinct browser and server clients. The browser client handles user interactions and OAuth flows in the browser, while the server client manages protected operations on the server with elevated privileges.

Set up OAuth callback routes that exchange provider tokens for Supabase sessions and store them in secure cookies. Implement token refresh logic to maintain valid sessions across requests without requiring user re-authentication.
