Hello world in node.js

Anatoly Mironov

I know, node.js has been present for a while. But I actually had no time to try it. I was surprised that now it is very straight forward to start with node.js. Allright, everything begins with Hello world. Eventhough it is available for allmost all combinations of operating systems and servers, the easiest way to test it was actually Ubuntu. To install just run:

sudo apt-get install nodejs
```Then make a new directory and create the hello.js:

mkdir hello cd hello vi hello.js

var http = require(‘http’); http.createServer(function(req, res) { res.writeHead(200, {‘Content-Type’: ’text/plain; charset=utf-8’ }); res.end(‘Salam tĕnce!’); }).listen(40113);

node hello.js


##### node.js on c9.io (Cloud9 IDE)

Even simpler way to try node.js is to create an app in Cloud9 IDE. [Begin with a hello-world app](http://support.cloud9ide.com/entries/20640198-lesson-3-writing-a-node-js-hello-world-program).

Update: [If you want to get the latest node package, you shouldn't install nodejs from apt](http://srirangan.net/2011-09-setup-node-js-and-npm-on-ubuntu). Just clone the node git repo, compile and update the PATH. npm package is preinstalled then:

git clone git:github.com/joyent/node.git cd node ./configure make sudo make install export PATH=${PATH}:/usr/local/bin

sudo apt-get install python-software-properties sudo add-apt-repository ppa:chris-lea/node.js sudo apt-get update sudo apt-get install nodejs npm


##### node.js and SharePoint

[Luc Stakenborg](http://allthatjs.com/2012/03/29/node-js-meet-sharepoint) has developed [a node.js package for retrieving data from SharePoint](http://search.npmjs.org/#/sharepoint). To use it, install two packages:

npm install xml2js npm install sharepoint

var SP = require(‘sharepoint’), site = ‘http://yourdomain.sharepoint.com/teamsite', username = ‘yourusername’, password = ‘yourpassword’;

var client = new SP.RestService(site), posts = client.list(‘Posts’);

var showResponse = function (err, data) { console.log(data); }

client.signin(username, password, function () { posts.get(showResponse) });

##### javascript console in Powershell

It can't be easier. If node is installed, just fire up PowerShell and type node: [![](https://sharepointkunskap.files.wordpress.com/2012/03/nodejs-powershell.png "nodejs-powershell")](https://sharepointkunskap.files.wordpress.com/2012/03/nodejs-powershell.png)
