Chat Room

Example project demonstrating real-time messaging and actor state management.

Getting Started

git clone https://github.com/rivet-dev/rivet.git
cd rivet/examples/chat-room
npm install
npm run dev

Features

• Real-time messaging: Broadcast messages to all connected clients instantly
• Persistent chat history: Messages automatically saved in actor state across restarts
• Multiple chat rooms: Each room is a separate actor instance with isolated state
• Event-driven architecture: Use actor events to push updates to clients in real-time

Implementation

The chat room demonstrates core Rivet Actor patterns for real-time communication:

• Actor Definition (src/backend/registry.ts): Defines the chatRoom actor with message history state and actions for sending messages and retrieving history
