Three main ways to deliver an error in Node.js throw the error pass the error to a callback emit an error event on an EventEmitter i guess you are looking for something like that: const EventEmitter = require('events'); class MyEmitter extends EventEmitter {} const myEmitter = new MyEmitter(); process.on('uncaughtException', (err) => { console.log('whoops! there was an error'); }); myEmitter.emit('error', new Error('whoops!')); // Prints: whoops! there was an error
