Xcode

Download and install Xcode from the Apple website. For Xcode 4.4 and above, install the Command Line Tools from the Xcode → Preferences menu, in the Downloads tab.

Installing Git

You can install Git via a package manager like Homebrew, or download an installer from the Git website.

Installing NVM

git clone git://github.com/creationix/nvm.git ~/.nvm
source ~/.nvm/nvm.sh
echo "source ~/.nvm/nvm.sh" >> ~/.bashrc
nvm install v0.8.5
nvm alias default v0.8.5

On OS X, you can ensure that ~/.bash_profile loads ~/.bashrc by making ~/.bash_profile contain the following:

[[ -s ~/.bashrc ]] && source ~/.bashrc

To use a version of Node.js that you previously installed, pass it to nvm use:

nvm use v0.8.4

Basic HTTP Server

var http = require('http');

var server = http.createServer(function(request, response) {
  var url = request.url;
  response.writeHead(200, {
    'Content-Type': 'text/html'
  });
  response.end("<h1>Hello from Node.js!</h1><p>You request the URL: " + url + "</p>");
});

server.listen(3000);
