What problem does it solve?

Create and review Cloudflare Durable Objects to coordinate stateful logic at the edge, enabling consistent per-entity storage, RPC methods, alarms, and WebSockets.

Core Features & Use Cases

  • One durable object per coordination unit (e.g., chat room, game session) to maintain isolation and consistency.
  • SQLite storage integration and migrations for durable state.
  • RPC-style methods for public endpoints and lifecycle management, with init and alarm handling.
  • Testing patterns with Vitest and Cloudflare tooling for local validation.

Quick Start

Create a Durable Object class named MySession and implement an RPC method to store and retrieve per-user state.
