Builds and manages stateful Durable Objects for real-time apps, WebSockets, and persistent serverless state.
This skill provides Claude with domain-specific expertise to implement Cloudflare Durable Objects (DO) effectively within the Workers ecosystem. It covers the full lifecycle of stateful development, including SQLite-backed storage (10GB limits), high-performance WebSocket hibernation, and the Alarms API for background tasks. It incorporates the latest 2025 updates such as 32MB WebSocket messages and the getByName() API, while preventing over 20 documented implementation errors related to class exports, migrations, and RPC serialization.
