PartyServer is a TypeScript library that enhances Cloudflare Durable Objects for building real-time applications with WebSockets, lifecycle hooks, and broadcasting. It includes companion packages for resilient WebSocket clients, Yjs collaborative editing, pubsub at scale, state sync, and task scheduling.

Use cases

• build real-time multiplayer apps on Cloudflare Workers
• add websocket rooms with broadcasting to Durable Objects
• implement collaborative editing with Yjs and CRDTs
• run pubsub at scale across global Durable Object instances
• sync server state to clients in real time
• schedule tasks at scale on Workers
• build AI agents with persistent realtime connections

When to choose

• you are building on Cloudflare Workers and Durable Objects
• you need realtime websocket features with reconnection and resilience
• you want collaborative editing or multiplayer state sync
• you need pubsub or scheduled tasks backed by Durable Objects

When to avoid

• you are not deploying on Cloudflare Workers
• you need a self-hosted realtime server outside Cloudflare
• you need a fully mature, long-stable library rather than a work in progress
