Hello World

A minimal example demonstrating RivetKit with a real-time counter shared across multiple clients.

Getting Started

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

Features

• Actor state management: Persistent counter state managed by Rivet Actors
• Real-time updates: Counter values synchronized across all connected clients via events
• Multiple actor instances: Each counter ID creates a separate actor instance
• React integration: Uses @rivetkit/react for seamless React hooks integration

Implementation

This example demonstrates the core RivetKit concepts with a simple counter:

• Actor Definition (src/actors.ts): Counter actor with persistent state and broadcast events
• Server Setup (src/server.ts): Minimal Hono server with RivetKit handler
• React Frontend (frontend/App.tsx): Counter component using useActor hook and event subscriptions
