Node.js Events Module

The events module allows Node.js programs to create and handle events.

Example

const EventEmitter = require("events");

const event = new EventEmitter();

event.on("greet", () => {
    console.log("Hello! Event occurred.");
});

event.emit("greet");

Output:

Hello! Event occurred.

Important Methods

emit() - Triggers an event
once() - Runs an event only once
removeListener() - Removes a listener
