Events in Node.js The EventEmitter Object You can assign event handlers to your own events with the EventEmitter object. In the example below we have created a function that will be executed when a "scream" event is fired. To fire an event, use the emit() method. var events = require('events'); var eventEmitter = new events.EventEmitter(); //Create an event handler: var myEventHandler = function () { console.log('I hear a scream!'); } //Assign the event handler to an event: eventEmitter.on('scream', myEventHandler); //Fire the 'scream' event: eventEmitter.emit('scream');
