Cloudflare Workers Explained

Are you curious about Cloudflare Workers but find the concept a bit confusing? In this video, we break down exactly how Cloudflare Workers work, why they are so powerful, and how they completely change the way we think about backend architecture. We compare traditional Node.js servers (and Express app deployment) with the modern, serverless approach of Cloudflare Workers. You'll learn about V8 isolates, global edge networks, sub-millisecond cold starts, and how to scale to millions of requests per second for pennies. We also walk through converting an Express app into a Cloudflare Worker using Hono.js, and explore the massive developer ecosystem including Workers AI, KV storage, D1 SQL databases, and Hyperdrive.
