Hapi. Event Emitters in NodeJs. In this tutorial we will be exploring the built-in events module in NodeJs and particularly the EventEmitter class through a couple of practical examples.
I'll start off by showing you how to create an instance of the EventEmitter and then move on to building our own Node module which inherits from the EventEmitter. So what exactly are event emitters? In NodeJs, any object that emits an event is an instance of the EventEmitter class which exposes 2 important functionalities: The ability to trigger events using eventEmitter.emit(someEvent, optionalData)The ability to assign one or more event handlers to a specific event using eventEmitter.on(someEvent, eventHandler) Let's start off with a simple example to illustrate how an instance of the EventEmitter class can be created and used to listen to and trigger events.

Top 10 Mistakes Node.js Developers Make. GitHub - auth0-blog/nodejs-jwt-authentication-sample: A NodeJS API that supports username and password authentication with JWTs. An early look at three high-impact ES6 features coming soon to Node.js - RethinkDB. Google is currently developing V8 4.9, which will ship in the upcoming Chrome 49 release.
V8 4.9 is a particularly exciting update, because it includes support for 91% of the ECMAScript 2015 (ES6) standard. When Node.js 6 launches with these V8 improvements, powerful new language features like destructuring assignment and proxies will work out of the box–without requiring special measures like command line flags or transpilers. Although Node 6.0 isn’t scheduled for release until April, you can experience a little bit of the future today by compiling Node’s vee-eight-4.9 branch from source code.
The vee-eight branches are where Node’s maintainers do the heavy lifting to make Node compatible with new versions of V8. The code from these branches is understandably not suitable for use in production environments, but it’s a fun a way to get an early look at coming improvements. The example above creates a rank variable that contains the value of the person object’s rank property. Resources: Maxogden/art-of-node. How do I get started with Node.js.
