nodejs/javascript remove URL from string

Question

Some users using URLs (Domains) in there usernames. They are sometimes much different, so i want to filter them out in there name

I can str.replace urls, if i know the urls, but there much different so i think regex is, how it works, but i try so much, but doesnt get any results...

I hope someone can help me.

I found that Regex for PHP but i need something for NodeJS / Javascript.

 $regex = '/^(.*?)';
 $regex .= "((https?|ftp)\:\/\/)?"; // SCHEME 
 $regex .= "([a-z0-9+!*(),;?&=\$_.-]+(\:[a-z0-9+!*(),;?&=\$_.-]+)?@)?"; // User and Pass 
 $regex .= "([a-z0-9-.]*)\.([a-z]{2,3})"; // Host or IP 
 $regex .= "(\:[0-9]{2,5})?"; // Port 
 $regex .= "(\/([a-z0-9+\$_-]\.?)+)*\/?"; // Path 
 $regex .= "(\?[a-z+&\$_.-][a-z0-9;:@&%=+\/\$_.-]*)?"; // GET Query 
 $regex .= "(#[a-z_.-][a-z0-9+\$_.-]*)?"; // Anchor 
 $regex .= '(.*?)$/i';

A username looks like

USERNAME Google.com

but can also

USERNAME www.GOOGLE.com

or

USERNAME GOOGLE.GG

You could block . in username. Even with regex users could do something like google(.)com, google . com etc. — Oen44

What you mean? If i replace "." in the name, than it looks Like USERNAME GOOGLEcom Not really better :/ — txen

Just don't let them use . in their username when registering. It's just a suggestion, not the only solution. You could create a massive regex to check different combinations. — Oen44

I use an API. I cannot check or let them create usernames. I get this from Login API — txen

You can use this regex to check for URL. It's basic. You can extend it if you need.

((http|ftp|https):\/\/)?([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])?

Remove ^ from regex to not look from start of a line. jsfiddle.net/0y2ftk8a
