netlify-edge-functions

Use Netlify Edge Functions with the Deno runtime to access geolocation data and route users based on location. Implement location-based redirects and personalization directly at the network edge for minimal latency.

The context.next() middleware pattern in Netlify Edge Functions passes control to the next handler for seamless request processing. It allows you to gate access and perform authentication checks before continuing execution.

Choose Netlify Edge Functions over serverless for latency-sensitive workloads requiring immediate response. Edge functions suit middleware and A/B testing, while serverless handles heavier compute tasks.

Yes, Netlify Edge Functions require the Deno runtime to execute code at the network edge. Deno enables low-latency middleware, geolocation decisions, and request manipulation within your edge functions.

You can implement A/B testing and feature flags at the edge using Netlify Edge Functions. Running experiments at the edge reduces latency and enables faster user redirection compared to server-side testing.

Perform lightweight authentication checks at the network edge by creating a Netlify Edge Function under the netlify/edge-functions directory. Use the context.next() middleware pattern to gate access and verify credentials.
