How to implement pub/sub pattern in JavaScript
The publish/subscribe pattern decouples components by allowing them to communicate through an event bus without knowing about each other. As the creator of CoreUI with over 25 years of JavaScript experience since 2000, I’ve used pub/sub for cross-component communication, plugin systems, and loosely coupled module architectures. The standard implementation stores subscriber functions in a map keyed by event name and calls them when events are published. This eliminates direct dependencies between modules.

The publish-subscribe pattern decouples communication between components by allowing publishers to emit events without knowing who subscribes, and subscribers to listen for events without knowing who publishes. As the creator of CoreUI with 26 years of JavaScript development experience, I’ve implemented pub/sub systems in applications serving millions of users, enabling loosely coupled architectures that scale efficiently across distributed features.
The most maintainable approach uses a central event bus with typed event channels.

The publish-subscribe pattern enables loose coupling between components by allowing publishers to emit events without knowing which subscribers will receive them. As the creator of CoreUI with 26 years of JavaScript development experience, I’ve implemented pub/sub systems in large-scale applications that coordinate communication between hundreds of independent modules without tight dependencies.
The most maintainable approach uses an event broker that manages subscriptions and message delivery.
