nextjs-supabase-auth

Set up Supabase auth in Next.js App Router by initializing the client with @supabase/ssr and configuring middleware to protect routes. This approach uses cookie-based sessions and server components to handle authentication securely.

Handle Supabase authentication tokens securely in Next.js server components by using @supabase/ssr with cookie-based sessions. This keeps sensitive credentials on the server side without exposing them to the client.

You can use server actions for Supabase login and signup flows in Next.js. Server actions manage authentication workflows and OAuth callbacks while maintaining secure token handling through cookie-based sessions.

@supabase/ssr works with Next.js middleware for protected routes. It enables server-first authentication flows by managing cookie-based sessions and validating user access before rendering server components.

Supabase sessions break across Next.js server and client components when cookie-based synchronization fails. Using @supabase/ssr ensures secure token handling and consistent session management across the server/client boundary.
