The Hitchiker's Guide to Event Driven Architectures
Join us on a fun journey through the world of Event-Driven Architectures! We’ll explore Node.js’s event-driven nature, the Event Loop, EventEmitter, Pub/Sub, and scaling with Kafka. Watch a live demo of an Emoji Reaction widget in action, and learn how events drive scalable, resilient systems. Don’t panic, it’s just events, and they’re easier than you think!
