Real-Time Web with Rails
Action Cable integrates WebSockets seamlessly into Rails, letting you build real-time features using the same patterns and conventions you already know.
Architecture
Action Cable has three components: Connection (WebSocket auth), Channel (pub/sub logic), and Subscription (client-side listener).
Building a Notifications System
Create a NotificationsChannel, stream for the current user, and broadcast from anywhere in your app — models, controllers, or background jobs.
Client-Side Integration
Subscribe to channels using the Action Cable JavaScript client. Handle received data to update the UI in real-time — show toasts, update badges, or append new content.
Scaling
For production, use Redis as the Action Cable adapter (or Solid Cable in Rails 8) for multi-server support.
