💬 Chat Example

Real-time multi-user chat application demonstrating WebSocket connections with Redis pub/sub messaging. This example showcases Falcon's excellent WebSocket performance and concurrent connection handling.

💭 Try the Chat

Open multiple browser tabs to see real-time messaging between users!

🔧 Technical Implementation

• WebSocket Connection: Uses Async::WebSocket::Adapters::Rails for WebSocket handling.
• Message Broadcasting: Redis pub/sub system for real-time message distribution.
• Concurrent Handling: Multiple users can join and chat simultaneously.
• Channel Support: Configurable chat channels (default: 'chat.general').

📋 Key Files

• app/controllers/chat_controller.rb - ChatController#connect - WebSocket handling
• lib/chat.rb - Chat::Redis - Redis client setup
• public/chat/client.js - client.js - Frontend WebSocket client

🚀 Performance Benefits

Traditional Ruby web servers struggle with persistent WebSocket connections. Falcon's async architecture allows handling thousands of concurrent chat connections with minimal resource usage.
