];

var invalid = [
  "rdar://1234",
  "http://",
  "http://.",
  "http://..",
  "http://../",
  "http://?",
  "http://??",
  "http://??/",
  "http://#",
  "http://##",
  "http://##/",
  "http://foo.bar?q=Spaces should be encoded",
  "//",
  "//a",
  "///a",
  "///",
  "http:///a",
  "foo.com",
  "http://-a.b.co",
  "http://a.b-.co"
];

valid.forEach(function(text) {
  if (!text.match(url_pattern)) {
      console.error("failed to match", text);
  }
});

invalid.forEach(function(text) {
  if (text.match(url_pattern)) {
      console.error("failed to not match", text);
  }
});

https://www.foo-bar.com doesn't work and this is a valid URL such as https://material-ui.com

Removing the - from [^\s\/?\.#-] section of the regex works for the scenarios mentioned above by @dersonsena. But then it also starts working for two or more hyphens (-) together (might need to enhance this case.

Updated regex after removing hyphen var url_pattern = /^(https?|ftp|torrent|image|irc):\/\/(-\.)?([^\s\/?\.#]+\.?)+(\/[^\s]*)?$/i;

Nice! =)

Thanks. I have referred a lot of docs for this.

Hello, your regular is revert incorrect result for correct url:
http://y-a.ru

It doesn't work for: https://off---white.com which has several hyphens. such a weird URL.
