📡 Server-Sent Events (SSE) Example

Demonstrates Server-Sent Events for one-way real-time updates from server to client. Perfect for live dashboards, notifications, and monitoring systems where bi-directional communication isn't needed.

⏱️ Live Event Stream

Watch real-time server events appear below. Each message shows the current server time:

🔧 Technical Implementation

• EventSource API: Uses browser's native EventSource for automatic reconnection.
• Streaming Response: Long-lived HTTP connection with text/event-stream content type.
• Real-time Updates: Server pushes timestamped messages every second.
• Connection Monitoring: Displays database connection pool statistics.

• app/controllers/sse_controller.rb - SseController#events - Server-Sent Events endpoint
• app/views/sse/index.html.erb - sse/index.html.erb - EventSource client code

🚀 Performance Benefits

SSE provides a lightweight alternative to WebSockets when you only need server-to-client communication. It is easier to use as it has automatic reconnection and built-in browser support. Falcon handles these persistent connections efficiently without blocking other requests.
