How CodePen leverages Cloudflare Workers and Cloudflare KV Storage

Interesting to see Chris Coyier and Stephen Shaw lift the hood of CodePen, detailing how they use Cloudflare Workers and Cloudflare’s KV Storage.

Cloudflare workers are like serverless functions that always run at the edge, making them incredibly fast. Not only that, but the tooling around them is really nice. They can run at particular routes on your own website, removing any awkward CORS troubles, and helping you craft clean APIs. But they also have special superpowers, like access to KV storage (also at the edge), image manipulation and optimization, and HTML rewriting.

💡 If you’re already familiar with the two concepts (and know how to link them together), feel free to fast forward to the 15-minute mark.
