Node.js server not working

I'm new too node.js and going with tutorials to get the basics

sys = require("sys");  
var http = require("http");  
var url = require("url");
var fs=require("fs");

http.createServer(function(request,response){  
    sys.puts("I got kicked");   
    //var _get = url.parse(request.url, true).query;
    request.on("end", function () {

      fs.readFile("test.txt", 'utf-8', function (error, data) {
         // Write headers.
         response.writeHead(200, {'Content-Type': 'text/plain'});
         // Increment the number obtained from file.
         data = parseInt(data) + 1;
         // Write incremented number to file.
         fs.writeFile('test.txt', data);
         // End response with some nice message.
        response.end('This page was refreshed ' + data + ' times!'); 
      });

   });

    //response.write("Hello World");  
    //response.end('Here is your data: ' + _get['data']);  
}).listen(8080);  
sys.puts("Server Running on 8080");

Got this code from http://net.tutsplus.com/tutorials/javascript-ajax/node-js-for-beginners/ but it's not working and I get "No data received" error from browser. seriously obsessed I want to know whats wrong with it. if i put response.end() out of request.on() it'll work but will not recognize data object... help!

You don't want to use request.on but you do want to put response.end in the readFile callback, otherwise it'll return before the data is read out of it:

var sys = require("sys");
var http = require("http");
var url = require("url");
var fs=require("fs");

http.createServer(function(request,response){
    sys.puts("I got kicked");
    //var _get = url.parse(request.url, true).query;
    fs.readFile("test.txt", 'utf-8', function (error, data) {
       // Write headers.
       response.writeHead(200, {'Content-Type': 'text/plain'});
       // Increment the number obtained from file.
       data = parseInt(data) + 1;
       // Write incremented number to file.
       fs.writeFile('test.txt', data);
       // End response with some nice message.
       response.end('This page was refreshed ' + data + ' times!');
    });

}).listen(8080);
sys.puts("Server Running on 8080");

And as @chris noted, your counter will be incremented by 2 every time.

Is just that you didn't really have anything on file on the first place.

By the way, you'll get 2 refresh for each one, thanks to favicon.ico requests

(I didn't get the error you mention btw. What node.js version you are using?)

UPDATE: Ok I did some edits, check it now
