You can manage stateful WebSocket connections on Cloudflare Workers by using Durable Objects to maintain persistent, globally-unique JavaScript objects with storage at the edge. This enables real-time collaboration without polling.

The best way to build a real-time collaborative chat room on Cloudflare is using Durable Objects. They manage per-session state and WebSocket connections, replacing sequential Worker calls with event-driven state machines.

Yes, you need the Cloudflare Workers Paid plan to use Durable Objects for stateful edge compute. This environment provides the necessary infrastructure compatibility for atomic operations and persistent storage.

Yes, you can perform atomic operations such as counters, locks, and compare-and-swap operations on Cloudflare Workers. Durable Objects provide globally-unique state management to ensure these operations execute atomically.

You should use Durable Objects instead of standard Cloudflare Workers when your application requires real-time collaboration, WebSocket connections, or stateful sessions across requests. Standard Workers are stateless, while Durable Objects manage persistent state.

You replace polling with event-driven state machines for live dashboards by implementing Cloudflare Durable Objects. They maintain persistent state and facilitate WebSocket connections, enabling real-time updates without continuous polling.
