Answer 1

Since you're using node, just use the built-in url.parse() method; you want the resulting hostname property:

var url=require('url');
var urls = [
  'http://domain.com:3000',
  'http://domain.com?pass=gas',
  'http://domain.com/',
  'http://domain.com'
];

UPDATED:

urls.forEach(function(x) {
  console.log(url.parse(x).hostname);
});
