Hello World

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

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
