Node.JS Can't get any output from the code

[zak100]

Hi,
I am running the following node.js code:

var http = require('http');
http.createServer(function (req, res){
   res.writeHead(200, {'Content-Type': 'text/plain'});
   res.end('Hello World!');
}).listen(8080);

I found the code from: https://www.w3schools.com/nodejs/

I am executing using the command: $ node helloworld2.js
Somebody please guide me.

Zulfi.

I see one error, function (, if it were function name( or function( with no space would help. X E.

@JosiahMaybe , can you please write what you are saying. I cant understand. I have also attached the image of original code.

That's not an error. In code, spaces are ignored (most of the time, with a few exceptions), so the space there does not change anything.

@zak100 Where are you expecting to get the output? In the command line or the browser? Have you opened http://localhost:8080 in the browser?

Just so we are clear what I was saying, there is a space between function and start parenthesis, change that to either no space or put a name of function. As @Johna said probably not needed though. I just know JS, not Node.js. X E.

That code works fine. Node.js just sits there listening to port 8080, and if you direct your browser to localhost:8080 you get the "Hello World". Spaces in the code of course play no part in this.

Hi @Johana, I want to first run on terminal. Please guide me. Zulfi.

Why ??? Are you scared of the browser ? Please provide some reasoning.
