• Module (and version) (if relevant):

C:\Users\Phil\Documents\node\new_project>node index.js
events.js:183
throw er; // Unhandled 'error' event

index.js source code if it helps.

const http = require('http');
const hostname = 'localhost';
const port = 3000;

const server = http.createServer((req, res) => {
	res.end('Welcome to Node!');
});

server.listen(hostname, port, () => {
	console.log('server listening on host: ${hostname} port: ${port}');
});

try a higher port please, say a 5 digit number.

[gireeshpunathil]

sorry, I did not look at your code. the listen takes port number as its first param:
https://nodejs.org/dist/latest-v9.x/docs/api/http.html#http_server_listen

So please try this code:

const http = require('http');
const hostname = 'localhost';
const port = 3000;

const server = http.createServer((req, res) => {
res.end('Welcome to Node!');
});

server.listen(port, () => {
console.log(`server listening on host: ${hostname} port: ${port}`);
});

Thanks. That looks like it did the trick!

Hello, firstly thanks to @gireeshpunathil . this solved by issue too.
I'm new to Node.js. I don't understand what the problem was here? Could you please explain? Just removing the hostname did the trick, why is that?

Thank You.

signature of listen API as per the doc:

server.listen([port][, host][, backlog][, callback]) for TCP servers

port: optional, default is an arbitrary port from the OS
host: optional, default is 0.0.0.0 (unspecified IPv4 address)

The problematic code had port and host order reversed:

server.listen(hostname, port, () => {
	console.log('server listening on host: ${hostname} port: ${port}');
});

the problem is fixed by placing them in the right order.

I tried this but it still returns
. This is my first time of doing Node.js. Thanks.
