This is a hobby project where I attempt to implement a simplified version of the Node.js Event Emitter functionality using Node.js and Typescript. Please note that this implementation is not intended for production use and serves solely as a learning exercise.
The Node.js Event Emitter is a powerful tool in Node.js that allows objects to emit and listen to custom events. It provides a way to facilitate asynchronous communication between different components of an application. In this hobby project, I explore the basics of building an Event Emitter from scratch, aiming to gain a deeper understanding of its inner workings.
- Event Registration: You can register event listeners for specific events.
- Event Emission: Emit events to trigger the execution of registered event listeners.
- Support for Multiple Listeners: The implementation supports multiple listeners for the same event.
const EventEmitter = require('../dist/eventEmitter');
// Create an instance of the event emitter
const emitter = new EventEmitter();
// Register an event listener
emitter.on('customEvent', (data) => {
console.log('Received data:', data);
});
// Emit an event
emitter.emit('customEvent', { message: 'Hello, world!' });
