Validate a ip address or domain name URL with user name and password in javascript

I have a regex for validating IP addresses and domain names which has been working well so far

/** Checks if a URL is valid */
export function isValidURL(str: string): boolean {
  var pattern = new RegExp(
    '^(https?:\\/\\/)?' + // protocol
      '((([a-z\\d]([a-z\\d-]*[a-z\\d])*)\\.)+[a-z]{2,}|' + // domain name
      '((\\d{1,3}\\.){3}\\d{1,3}))' + // OR ip (v4) address
      '(\\:\\d+)?(\\/[-a-z\\d%_.~+]*)*' + // port and path
      '(\\?[;&a-z\\d%_.~+=-]*)?' + // query string
      '(\\#[-a-z\\d_]*)?$',
    'i'
  ); // fragment locator
  return !!pattern.test(str);
}

The problem is when I use a username and password it breaks.

Is there a solution that would pass the URL as valid if including a username and password in the URL

You'd just need to add a new line for the user/pass pattern after your "protocol" pattern. What are the requirements for usernames and passwords?

A simple one would looks something like this (assumes usernames are only letters & numbers):

(\w+?:.+@)?
