regex / url-pattern

regex match URL — http, https, and optional path

Quick Answer

# Match http/https URLs
/https?:\/\/[^\s<>"{}|\\^\[\]]+/

// JavaScript — extract all URLs from text
const text = 'Visit https://example.com/path?q=1 or http://foo.io';
text.match(/https?:\/\/[^\s<>"{}|\\^\[\]]+/g)
// ['https://example.com/path?q=1', 'http://foo.io']

Usage

Extract hyperlinks from plain text, validate URL input, or detect URLs in user content.

Other causes & fixes

Stricter URL pattern with domain validation

/https?:\/\/(?:[a-zA-Z0-9-]+\.)+[a-zA-Z]{2,}(?:\/[^\s]*)?/

// Matches:
//   https://example.com
//   https://sub.domain.co.uk/path/to/page?query=1#fragment
// Does not match:
//   http://localhost  (no TLD)

Python — extract URLs

import re

URL_RE = re.compile(r'https?://[^\s<>"{}|\\^\[\]]+')

text = 'See https://example.com/path for details'
urls = URL_RE.findall(text)
# ['https://example.com/path']

Validate a complete URL with named groups

/^(?P<scheme>https?):\/\/(?P<host>[^\/?#]+)(?P<path>[^?#]*)(\?(?P<query>[^#]*))?(#(?P<fragment>.*))?$/

Prefer URL() constructor for validation in JS

function isValidUrl(str) {
  try {
    new URL(str);
    return true;
  } catch {
    return false;
  }
}
isValidUrl('https://example.com');   // true
isValidUrl('not-a-url');             // false
