Best for

  • Building real-time WebSocket APIs with integrated Supabase auth and RLS
  • Processing webhook events from third-party services with signature verification
  • Creating AI/LLM endpoints that stream responses with proper token management
  • Implementing cron-triggered background jobs using pg_cron integration
  • Building serverless API proxies that aggregate external service data

What you'll get

  • Complete TypeScript function with import maps, CORS handling, JWT verification, database queries with RLS, and structured error responses
  • Webhook processor with HMAC signature validation, idempotency handling, database updates, and real-time broadcast integration
  • Streaming AI endpoint with token management, rate limiting, proper async/await patterns, and OpenAI SDK integration
Not designed for ↓
  • ×Long-running processes over 150 seconds (use pg_net or external workers)
  • ×Heavy computational tasks requiring more than 50MB memory
  • ×Direct database administration or schema migrations
  • ×Client-side JavaScript development or frontend frameworks
Expects

Clear function requirements including trigger type (HTTP/webhook/cron), authentication needs (user JWT vs service-role), and expected input/output formats with any third-party integrations.

Returns

Complete TypeScript edge function code with proper error handling, security validations, Supabase client integration, and deployment configuration files.
