  RESTFul Folder is a simple and quick script to stub out RESTful webservices. It simply
	takes whatever folder you run it in and converts it to a rest service.
	
	Setup: Create a root folder and app.js.  Put this script in app.js.
	Any subfolders you create become endpoints to your requests.  In those folders
	create a file per request method.  So if you create a "post.json" file, any posts
	requests made to the server to that files directory, will return the contents of post.json.
	
	Yeah, that simple.
	
	Example:
		MyService/
			- app.js
			- user/
				- get.json
				- create/
					- post.json
				
		Stub URLS:
		GET: 	localhost:8080/user/
		POST: 	localhost:8080/user/create/
 */

var http  = require('http'),
    port  = 8080,
    host  = "0.0.0.0";

http.createServer(function(request, response){
	
	var url	 	= require('url').parse(request.url).pathname,
	    path	= require('path'),
	    fs		= require('fs'),
	    filename	= path.join(process.cwd(), url),
	    method	= request.method;
	
	console.dir(method.toUpperCase() + ": " + url);
	
	fs.exists(filename, function(exists){
		if(!exists)
		{
			response.writeHead(404, {"Content-Type": "text/plain"});
			response.write("404 Not Found\n");
			response.end();
			
			return;
		}
		
		if(fs.statSync(filename).isDirectory())
			filename += '/' + method;
			
		fs.readFile(filename + ".json", function(error, data) {
			if(error)
			{
				response.writeHead(500, {"Content-Type": "text/plain"});
				response.write(error + "\n");
				response.end();
			}
			
			response.writeHead(200, {"Content-Type": "application/json"});
			response.write(data + "\n");
			response.end();
			
			return;
		});
		
	});
	
}).listen(port, host);

console.log("Server running at: " + host + ":" + port);
