Answer 2

I use Nod's url module for verification. It parses the address (always with the protocol) and decomposes it into components - protocol, name, port, path, parameters, etc., and immediately converts the name into a panic code - there is no need to invent anything with national characters in the regexp.

function validateUrl(address) {
  let url = require('url');
  let addressRegexp = new RegExp('^([\\w\\-]+?\\.?)+?\\.[\\w\\-]+?$');

  if (address.search(/^(ftp|http|https):\/\//) === -1) { address = 'http://' + address; }	

  let hname = url.parse(address).hostname;

  if (hname.length < 4 || hname.length > 255 || !addressRegexp.test(hname)) {
    throw new WrongInput('');
  }
}
