Error in worker

[Вадим Бударин]

in order to detect the browser, you need to take into account that the code can be executed in the worker and there is no window, but there is self

root = typeof window !== "undefined" ? window : null;

should be rewritten as

root = self instanceof Window || self instanceof ServiceWorkerGlobalScope || self instanceof Worker ? self : null;

Hey, if anyone else finds this issue like I did and is using cloudflare workers, here's what worked for me:

import {monotonicFactory} from 'ulid'
// or import {factory} from 'ulid'

const prng = () => {
  const buffer = new Uint8Array(1)
  crypto.getRandomValues(buffer)
  return buffer[0] / 0xff
}
export const ulid = monotonicFactory(prng) // or factory(prng)

This will bypass the code that checks for browser crypto and allow you to set your own. The PRNG function is the same as used internally with a different global reference.

I think this package may be abandoned, I'm working on potentially forking it.

Friendly reminder that we now have worker support over on ulidx, which is maintained unlike this library.
