Our Commentary ​

Durable Objects are genuinely one of Cloudflare's coolest features. The idea of a single-instance, globally distributed object is mind-bendingly powerful for certain use cases. I've always found them a bit tricky to wrap my head around, so a good tutorial from Frontend Masters is always welcome. This is a solid piece for anyone looking to build truly stateful serverless applications.
