edge-computing-patterns
Deploy to edge runtimes (Cloudflare Workers, Vercel Edge, Deno Deploy) for globally distributed, low-latency applications. Master edge middleware, streaming, and runtime constraints for 2025+ edge computing.
Why this skill is useful
Provides specific edge computing patterns and code examples for deploying applications on Cloudflare Workers, Vercel Edge, and Deno Deploy that the AI wouldn't reliably generate on its own.

What this skill does
Edge Computing Patterns Overview Edge computing runs code closer to users worldwide, reducing latency from seconds to milliseconds. This skill covers Cloudflare Workers, Vercel Edge Functions, and Deno Deploy patterns for building globally distributed applications. When to use this skill: Global applications requiring <50ms latency Authentication/authorization at the edge A/B testing and feature flags Geo-routing and localization API rate limiting and DDoS protection Transforming responses (image optimization, HTML rewriting) Platform Comparison Feature Cloudflare Workers Vercel Edge Deno Deploy --------- ------------------- ------------- ------------- Cold Start <1ms <10ms <10ms Locations 300+ 100+ 35+ Runtime V8 Isolates V8 Isolates Deno Max Duration 30s (paid: unlimited) 25s 50ms-5min Free Tier 100k req/day 100k req/month 100k req/month Cloudflare Workers Vercel Edge Functions Edge Runtime Constraints ✅ Available: fetch, Request, Response, Headers URL, URLSearchParams TextEncoder, TextDecoder ReadableStream, WritableStream crypto, SubtleCrypto Web APIs (atob, btoa, setTimeout, etc.) ❌ Not Available: Node.js APIs (fs, path, childprocess) Native modules Some npm packages File system access Common Patterns Authentication at Edge Rate Limiting Edge Caching Best Practices ✅ Keep bundles small (<1MB) ✅ Use streaming for large responses ✅ Leverage edge caching (KV, Durable Objects) ✅ Handle errors gracefully (edge errors can't be recovered) ✅ Test cold starts and warm starts ✅ Monitor edge function performance ✅ Use environment variables for secrets ✅ Implement proper CORS headers Resources Cloudflare Workers Documentation Vercel Edge Functions Deno Deploy
