What is @types/events?
The @types/events package provides TypeScript type definitions for the Node.js 'events' module, which is used for handling events in an application. This package does not contain functionality by itself but offers type annotations for TypeScript developers to ensure type safety and better development experience when working with event-driven programming in Node.js.
EventEmitter Type Definitions
Provides type definitions for creating and using an EventEmitter to handle custom events. The code sample demonstrates how to create an EventEmitter, subscribe to an event with a specific type of listener function, and emit an event.
import { EventEmitter } from 'events';
const emitter: EventEmitter = new EventEmitter();
emitter.on('event', (message: string) => {
console.log(`Received message: ${message}`);
});
emitter.emit('event', 'Hello World!');
