Working with events is fundamental to Node.js architecture, enabling asynchronous communication between different parts of your application. As the creator of CoreUI, a widely used open-source UI library, and with over 25 years of experience in software development, I’ve built numerous Node.js applications where event-driven patterns are essential for scalability. The most effective approach is using Node.js’s built-in EventEmitter class, which provides a robust foundation for creating and handling custom events. This pattern allows for loose coupling between components and enables reactive programming paradigms.
