Frequently Asked Questions about Supabase-edge-functions
What is Supabase-edge-functions?
Supabase Edge Functions are serverless functions deployed at the edge using Deno runtime, enabling developers to run backend logic close to users with low latency.
What are the primary use cases for Supabase-edge-functions?
RESTful API endpoints for Supabase apps. Custom authentication or authorization flows. Processing webhooks and events. Serverless business logic triggered by frontend requests. Realtime event handling and notifications
What are the strengths of Supabase-edge-functions?
Ultra-low latency for global users. Integrated seamlessly with Supabase backend. Serverless - no server provisioning required. Supports modern TypeScript/JavaScript. Easy to deploy and scale automatically
What are the limitations of Supabase-edge-functions?
Execution time is limited (short-lived requests). Vendor lock-in to Supabase platform. Cold starts may affect first requests. Limited runtime compared to full server environments. Debugging and monitoring require Supabase tooling
