Node.js Question

How to run a hello.js file in Node.js on windows?

I am trying to run a hello world program written in javascript in a separate file named hello.js

Currently running windows version of node.js.

The code runs perfectly in console window but how do I reference the path in windows environment.

C:\abc\zyx\hello.js


in Unix I guess it is showing $ node hello.js

I'm absolutely new to Node.js Please correct me if I am doing something wrong.

I tried

> node C:\abc\zyx\hello.js
----didn't work

> C:\abc\zyx\hello.js
--didn't work

UPDATE1:

Added node.exe to the folder where hello.js file is sitting.

Added path point to the folder c:\abc\zyx\ and I get an error that says

ReferenceError: hello is not defined

see contents of hello.js

setTimeout(function() {
console.log('World!');
}, 2000);
console.log('Hello');


UPDATE 2:

So far I have tried all these version and none of them seems to work. May be I am doing something completely wrong.

>node hello.js
>$ node hello.js
>node.exe hello.js
>node /hello.js
>node \hello.js
> \node \hello.js
> /node /hello.js
> C:\abc\xyz\node.exe C:\abc\xyz\hello.js
> C:\abc\xyz\node.exe C:/abc/xyz/hello.js
> hello.js
> /hello.js
> \hello.js
>node hello


Refer to my file structure

RESOLVED:
Instead of running node.exe, try running in command prompt with the following option and it worked.

c:\>node c:\abc\hello.js
Hello
World! (after 2 secs)

Answer

Here are the exact steps I just took to run the "Hello World" example found at http://nodejs.org/. This is a quick and dirty example. For a permanent installation you'd want to store the executable in a more reasonable place than the root directory and update your PATH to include its location.

  1. Download the Windows executable here: http://nodejs.org/#download
  2. Copy the file to C:\
  3. Create C:\hello.js
  4. Paste in the following content:
    var http = require('http');
    http.createServer(function (req, res) {
      res.writeHead(200, {'Content-Type': 'text/plain'});
      res.end('Hello World\n');
    }).listen(1337, "127.0.0.1");
    console.log('Server running at http://127.0.0.1:1337/');
  1. Save the file
  2. Start -> Run... -> cmd
  3. c:
  4. C:>node hello.js

    Server running at http://127.0.0.1:1337/
    

That's it. This was done on Windows XP.
