Guide to Installing Node.js on a Raspberry Pi

Node.js is a open source platform to create network applications using JavaScript. The applications are executed on the server and not as usual on the client in the browser.
Integrated modules, such as the HTTP-module, enable the realisation of web servers. Additional modules can be simply installed using the supplied package manager npm.

   Bash

   Copy

   and add the following code:

   var http = require('http');
   http.createServer(function (request,response) {
