Starting with a Node.js webserver

Before starting to explain how you start your first Node.js project for building a simple web server I will first explain you what Node.js is. To do so I just include a quote of the Node.js themself, because I don’t like to reinvent the wheel. Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. The next thing you should know is about the Node.js Package Manager (NPM). Using NPM you can benefit from the thousands of open source packages so you won’t have to build everything yourself. I suppose you already have installed Node.js. Let’s start with a simple Hello World in Node.js by creating a file called hello-world.js and execute our script to show the result. hello-world.js1console.log('Hello World'); We can execute the script using following command. (On Windows open the Node.js command prompt) Navigate to your folder containing the just created hello-world.js file and execute the script using node. 123456Your environment has been set up for using Node.js 4.1.1 (x64) and npm.Press any key to continue . . .C:\Users\Marco> cd MyHelloWorldCodeFolderC:\Users\Marco\MyHelloWorldCodeFolder> node hello-world.jsHello World
