Can't get my port to show Hello World...

Here's my code

const http = require('http');

//const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World');
});

server.listen(() => {
  console.log(`Server running at http://<workspace>/`);
});

this is the error I get

Problem solved. I didn't run the app.js in the terminal. Once I did node app.js in the terminal and got the server running. I can see Hello World.

Hi Clint, I did my code like yours but I still can't seem to see the Hello World. How did you solve yours? I dont quite understand your solution from your comment above. PS: I am using the workspace btw.
