Learn to build a self-hosted real-time notification system for Drupal using Node.js, Redis, and WebSockets in this 46-minute conference talk. Discover how to implement live updates, push notifications, and chat systems without relying on commercial messaging services like Firebase or Pusher. Explore the system architecture that combines Redis, WebSocket, and HTTP APIs following ZeroMQ-inspired design principles for simplicity, speed, and decoupling. Master the security model that separates internal and external communication, with Drupal connecting via private HTTP API while maintaining controlled public WebSocket access through client ID validation. Examine the notification_server module for Drupal integration, including configuration, usage, and publishing structured messages from Drupal services. Understand frontend implementation techniques for connecting browsers to WebSocket servers, subscribing to channels, and displaying real-time events in live components. Watch live demonstrations showing the complete flow from Drupal to client, including HTTP and WebSocket interfaces with multiple clients on different channels. Gain practical deployment and scaling knowledge covering Redis setup, production security, WebSocket connection scaling, and failover handling. Requires basic Drupal module experience, PHP and JavaScript familiarity, and understanding of HTTP and WebSocket concepts, with Redis or Node.js experience helpful but not mandatory.
