Netlify Edge Functions

This walks Claude through building Netlify Edge Functions, the Deno-based middleware that runs on their global edge network. You'll want this when you need low-latency responses for auth checks, geo-based redirects, A/B testing, or request/response manipulation. It covers the context.next() middleware pattern, geolocation APIs, environment variables via Netlify.env, and the practical tradeoffs between edge and serverless (edge gets you 50ms CPU time and proximity to users, serverless gets you 15 minutes and heavier compute). The guidance on when to choose each is actually useful, not just spec regurgitation.
