How can I use the new URL API to get request details?

Question

After following a tutorial on Node.js I tried to get the details of a request like so:

const url = require('url');

http
    .createServer((req, res) => {
        *let parsedUrl = url.parse(req.url, true);*
        
        res.write('---------->  ');
        res.write(parsedUrl.search);
        res.write(parsedUrl.search);
        re.write(parsedUrl.pathname);
        res.write('  <----------');
        res.end();
    })
    .listen(3000, () => cl('Listening on port 3000.'));

This is working fine but I get a warning that url.parse() is deprecated and instead I should use new URL() API. But the problem is that with url.parse() I can pass the req.url as parameter whereas with new URL() I have to pass a string as parameter, therefore I can't use req.url to get the request details. Or is something I'm missing?

http
    .createServer((req, res) => {
        *let myUrl = new URL(req.url.toString());*
        
        res.write(myUrl);
        res.end();
    })
    .listen(3000, () => cl('Listening on port 3000.'));

If curl this URL curl http://localhost:3000/test?hello=world, I get this error TypeError [ERR_INVALID_URL]: Invalid URL: /test?hello=world

import http from "node:http"
import { URL } from "node:url"

const PORT = 3000

const server = http.createServer((req, res) => {
  const url = new URL(`http://${req.headers.host}${req.url}`)
  return res.end(url.href)
})

server.listen(PORT, () => `Server is running on port ${PORT}`)
