Supabase authentication in Next.js supports sign-up, OAuth, and MFA across Server Components, Server Actions, Client Components, Middleware, and Route Handlers. You implement these flows using detailed integration patterns and TypeScript client examples tailored for the Next.js framework.

Real-time subscriptions in Supabase allow you to track database changes, broadcast messages, and monitor user presence. You set up real-time functionalities by subscribing to database events through the Supabase client, enabling instant updates for collaborative application features.

Supabase supports vector search through pgvector integration for AI-powered similarity matching. You use PostgreSQL with pgvector extensions to store and query vector embeddings, enabling semantic search capabilities directly within your database operations.

Supabase supports serverless edge functions for developing and deploying backend logic without managing infrastructure. You write and deploy edge functions to handle API routes, process webhooks, and execute server-side code close to your users for reduced latency.

Supabase storage allows you to manage file uploads, downloads, and generate public or signed URLs. You handle file storage operations through the Supabase client, controlling access to private assets with signed URLs and serving public assets directly.

Understanding PostgreSQL is required for Supabase backend development because Supabase is built on PostgreSQL. You need knowledge of PostgreSQL database management, advanced queries, and function calls to effectively use Supabase as a backend-as-a-service architecture.
