A solid implementation guide for Cloudflare Durable Objects that actually gets the patterns right. Covers the full lifecycle from wrangler configuration and SQLite migrations to RPC methods, alarms, and WebSocket handling. The anti-patterns section alone will save you from common mistakes like single global DOs or blocking concurrency on every request. Includes proper Vitest testing setup and emphasizes retrieving from current Cloudflare docs over outdated knowledge. If you're building anything stateful on Workers like chat rooms, multiplayer games, or booking systems, this handles the coordination primitives and storage patterns you need.
