Regex for finding URLs inside text

Question

I want to find bulletproof RegEx for URLs inside text using JavaScript (I'm replacing urls with <a> tags), My current was RegEx:

var url_re = /https?:\/\/(?:(?!&[^;]+;)[^\s:"'<>)])+/g;

It was working but didn't match urls with port (like http://localhost:8080 ). Does this RegEx will match all urls or I miss something too?

var url_re = /https?:\/\/[^\/\s"'<>]+\/?(?:(?!&[^;]+;)[^\s:"'<>)])+/g;

Or maybe there is shorter/better regex for urls.

Answer 1

You can probably use this regex:

\bhttps?:\/\/(?:(?!&[^;]+;)[^\s"'<>)])+\b
