NodeJS is JS runtime built on Chrome V8 JavaScript engine. NodeJS uses event-driven, non-blocking I\/O model – that makes it lightweight and efficient.<\/p>\n

NodeJS has a package system, called npm<\/code> – it’s a largest ecosystem of open source libraries in the world.<\/p>\n

Current stable NodeJS version is v4.0.0<\/code> – it’s included new version of V8 engine and ES6 features.<\/p>\n

NodeJS installation (on Ubuntu) is very simple process, you should run only two commands in your trminal:<\/p>\n

sudo apt-get update<\/code><\/p>\n

sudo apt-get install nodejs<\/code><\/p>\n

Also we should install package system: sudo apt-get install npm<\/code><\/p>\n

For managing installed NodeJS versions on our server, I used “tj\/n”<\/a> tool. We can install it using NPM: npm install -g n<\/code><\/p>\n

The simple http-server on NodeJS looks like this:<\/p>\n

var http = require('http');\n\nhttp.createServer(function (request, response) {\n  response.writeHead(200, {'Content-Type': 'text\/plain'});\n  response.end('Hello World\\n');\n}).listen(8124);\n\nconsole.log('Server running at http:\/\/127.0.0.1:8124\/');\n<\/code><\/pre>\n
For handling requests from different URL we can use  package “httpdispatcher”<\/p>\n
For creating more complex applications using NodeJS we need more complex solutions. At this point we can start to use NodeJS framework – Express<\/a><\/p>\n
Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.<\/p>\n
We can install Express in our project using npm: npm install express --save<\/code><\/p>\n
When we using Express we’ve got a lot cool things, such as:<\/p>\n
