How to run server written in js with Node.js

Question

I have installed node.js from here http://nodejs.org/ . in my windows8 machine. copied the example server code in my server.js file

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/');

then opened the node.js prompt and written node c:/node/server.js but nothing happens. I am a php developer just trying hands on it, any guidelines will really be helpful.

You don't need to go in node.js prompt, you just need to use standard command promt and write

node c:/node/server.js

this also works:

node c:\node\server.js

and then in your browser:

http://localhost:1337

Nodejs is a scripting language (like Python or Ruby, and unlike PHP or C++). To run your code, you need to enter a command in the terminal / shell / command prompt. Look for an application shortcut in your operating system by one of those names.

The command to run in the terminal will be

node server.js

But you will first need to browse in the terminal to the same folder as the file server.js. The syntax for using the terminal varies by operating system, look for its documentation.

While node.js is not a language at all, but an environment to run a javascript engine. – galingong Mar 16 '18 at 17:58

I open a text editor, in my case I used Atom. Paste this code

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/');

and save as

helloworld.js

in

c:\xampp\htdocs\myproject

directory. Next I open node.js commamd prompt enter

cd c:\xampp\htdocs\myproject

node helloworld.js

next I open my chrome browser and I type

http://localhost:1337

and there it is.

Just go on that directory of your JS file from cmd and write node jsFile.js or even node jsFile; both will work fine.

If you are in a Linux container, such as on a Chromebook, you will need to manually browse to your localhost's address. I am aware the newer Chrome OS versions no longer have this problem, but on my Chromebook, I still had to manually browse to the localhost's address for your code to work.

To browse to your locahost's address, type this in command line: sudo ifconfig

and note the inet address under eth0.

Otherwise, as others have noted, simply type node.js filename and it will work as long as you point the browser to the proper address.

Hope this helps!
