My attempt in making a CodeIgniter routing server.

NodeIgniter Server.js

var http = require('http');
var util = require('util');
var path = require('path');

var chromesMinimumByteFix = "                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 ";

var server = http.createServer(function(req, res){
	var pathParts = req.url.split('/');
	pathParts.shift();
	
	var controllerName = pathParts[0] || 'index',
			exportsName = pathParts[1] || 'index';
	var controllerPath = process.cwd() + '/controllers/' + controllerName + '.js';
	
	if (path.existsSync(controllerPath))
	{
		var controller = require(controllerPath);
		
		if (typeof controller[exportsName] != 'undefined')
		{
			// Ignore this here. theThis will contain API and be separated into another file.
			var theThis = {
				req: req,
				res: res,
				load: {
					view: function(file, data) {
						with (theThis.res)
						{
							writeHead(200, {'content-type': 'text/html'});
							end('This is from the <em>load.view</em>');
						}
					}
				}
			};
			
			controller[exportsName].call(theThis);
		}
		else
		{
			res.writeHead(404, {'content-type': 'text/plain'});
			res.write("404 Error: Missing export function "+ exportsName +" in controller file located at " + controllerPath);
			res.end(chromesMinimumByteFix);;
		}
	}
	else
	{
		res.writeHead(404, {'content-type': 'text/plain'});
		res.write("404 Error: Missing controller file located at " + controllerPath);
		res.end(chromesMinimumByteFix);
	}
	
});

server.listen(80, 'localhost');
