Edge Function CDN (TypeScript, Cloudflare Workers, Wrangler) overview

A serverless edge computing stack where TypeScript functions execute at Cloudflare's global network edge, running within milliseconds of end users across 300+ data centers. Cloudflare Workers provide the V8-based runtime, with KV offering eventually-consistent global key-value storage and D1 providing edge-local SQLite-compatible relational queries. Hono serves as the lightweight HTTP framework, optimized for edge constraints like 128 MB memory limits and 30-second CPU time budgets. TypeScript ensures type safety across request handlers and middleware. The tradeoff is the constrained runtime environment (no Node.js APIs, limited storage options) and eventual consistency of distributed state, but the latency improvements and zero cold-start characteristics make this ideal for API gateways, A/B testing, personalization, and real-time content transformation at the edge.
