Robert and I jump on to chat about Cloudflare’s product Durable Objects. It’s part of their Workers platform, which we already use at CodePen a good bit, but with Durable Objects…

Global Uniqueness guarantees that there will be a single instance of a Durable Object class with a given ID running at once, across the world. Requests for a Durable Object ID are routed by the Workers runtime to the Cloudflare data center that owns the Durable Object.

In their intro blog post a few years back, they call the “killer app” real-time collaborative document editing, which is obviously of interest to us. So we’ve been tinkering and playing with how that might work with CodePen’s future technology.
