Back End Development and APIs Projects - URL Shortener Microservice

[fk19]

Tell us what’s happening:
dns.lookup doesn’t work when i get the hostname from the url - it accepts all kinds of strings as valid hostnames. When i test manually with a string containing ‘example’ it works.

url.parse is deprecated. Use the URL constructor instead (WHATWG URL API).

const url = require('url');
const dns = require("dns");

const nodeURL = url.parse('ftp:/john-doe.invalidTLD').hostname;
const WHATWG_URL = new URL('ftp:/john-doe.invalidTLD').hostname

console.log(nodeURL) // null
console.log(WHATWG_URL) // ftp:/john-doe.invalidTLD


dns.lookup(nodeURL, (error, address, family) => {
  if (error) {
    console.error(error);
  } else {
    console.error('No error'); // No error
  }
});
