This is cool.

"Every big-name real-time collaborative document editor works this way. But for many web developers, especially those building on serverless infrastructure, this kind of solution has long been out-of-reach. Standard serverless infrastructure -- and even cloud infrastructure more generally -- just does not make it easy to assign these coordination points and direct users to talk to the same instance of your server.

Durable Objects make this easy. Not only do they make it easy to assign a coordination point, but Cloudflare will automatically create the coordinator close to the users using it and migrate it as needed, minimizing latency. The availability of local, durable storage means that changes to the document can be saved reliably in an instant, even if the eventual long-term storage is slower. Or, you can even store the entire document on the edge and abandon your database altogether."
