How I can run this script in node.js?

I have install all modules need to run this script using CMD. When I am run this script in node.js through webmatrix:

var http = require('http');
var everyauth = require('everyauth');
var app = require('express').createServer();

app.get('/', function(request, response) {
    response.send('Hello Express!!');
});

app.listen(2455);

It's not working. The error is:

iisnode encountered an error when processing the request.

HRESULT: 0x2
HTTP status: 500
HTTP reason: Internal Server Error
You are receiving this HTTP 200 response because system.webServer/iisnode/@devErrorsEnabled configuration setting is 'true'.

In addition to the log of stdout and stderr of the node.exe process, consider using debugging and ETW traces to further diagnose the problem.

The node.exe process has not written any information to the stdout or stderr.

I have tried with different different script from blog but they do not work. I tried Steven Sanderson's template in webmatrix and that does work.

To use your application with iisnode, you have to use port/socket supplied by iisnode (as in this case you're using IIS as a webserver instead of the one bundled in node).

Replace the last line with app.listen(process.env.port || 2455);, so that it will both work well with iisnode and be available on port 2455 when run with node.exe app.js.

Use

app.listen(process.env.port || 2455);

instead of `

app.listen(portno);

cause it's iisnode web server.
