要点
Build stateful, coordinated applications on Cloudflare's edge with persistent storage and RPC methods.
- Designed for coordination patterns: chat rooms, multiplayer games, booking systems, and per-entity state management using deterministic routing via
getByName() - Includes SQLite storage with synchronous
sql.exec(), KV storage, alarms for scheduled per-entity work, and WebSocket support - Provides RPC method calls (preferred over fetch handlers),
blockConcurrencyWhile()for initialization, and parent-child DO relationships for sharding - Covers wrangler configuration, migrations, Workers integration, and testing with Vitest; biases toward live Cloudflare docs over pre-trained knowledge
