const url = require('url');

const fullUrl = (req) => {
  return url.format({
    protocol: req.protocol,
    host: req.get('host'),
    pathname: req.originalUrl
  });
}

to define the fullUrl function that takes the Express request req object.

And then we call url.format with an object that has the protocol, host, and pathnameset from the URL components inreq`.

protocol has the protocol like http or ftp.

host has the first segment of the URL after the protocol.

And pathname has the rest of the URL.
