regex for url

Comment

// All are 'non-capturing' regular expressions.

// General format of a URL in a RegEx:
(?:(?:https?|ftp):\/\/)?(?:www\.)?[^/\r\n]+(?:/[^\r\n]*)?

// To enforce the protocol
(?:https?|ftp):\/\/(?:www\.)?[^/\r\n]+

// To enforce the protocol and trailing slash
(?:https?|ftp):\/\/(?:www\.)?[^/\r\n]+(?:/[^\r\n]*)

// To enforce file extensions like .html or .png:
(?:(?:https?|ftp):\/\/)?(?:www\.)?[^/\r\n]+(?:/[^\r\n]*)(?:[a-zA-Z0-9]+.(?:html|png|webp|js))

// To implement in GO (https://go.dev), add an extra backslash (' \ ') to every unescaped backslash (' \ ')

// For the first format, that is:
(?:(?:https?|ftp):\\/\\/)?(?:www\\.)?[^/\r\n]+(?:/[^\r\n]*)?

// You do not need to add the extra backslash to the '\r' and '\n' because it is handled natively

Comment

function isValidUrl(url) {
  // Regular expression pattern to match a valid URL
  const urlPattern = /^(http|https):\/\/([\w\-]+\.)+[\w\-]+(\/[\w\u002E\u003C\u003E]*)*(#[\w\-]+)*(\?[^\s]+)*$/;

  // Test if the provided URL matches the pattern
  return urlPattern.test(url);
}

// Example usage and validation
const inputUrl = 'https://example.com';
console.log(isValidUrl(inputUrl));  // Output: true

const invalidUrl = 'example.com';
console.log(isValidUrl(invalidUrl));  // Output: false
