Cloudflare Workers

Run code at the edge. Build low-latency serverless applications using Cloudflare Workers, KV Storage, and Durable Objects.

Edge computing moves logic closer to the user. This course teaches you to build applications on the Cloudflare Workers platform using V8 isolates. You will learn to intercept HTTP requests, modify headers, and serve dynamic content with near-zero latency globally. We explore KV (Key-Value) storage for caching, Durable Objects for strong consistency, and R2 for object storage. This is the future of high-performance web applications.
