Question: How to support JSDOMNodeJSEnv?

[xerial]

If JSDOMNodeJSEnv is used, crypt npm module is not loaded (require("crypto")), so using UUID.randomUUID() in Scala.js will throw java.lang.UnsupportedOperationException.

build.sbt:

Test / jsEnv := new org.scalajs.jsenv.jsdomnodejs.JSDOMNodeJSEnv()

An example exception:

java.security.SecureRandom is not supported on this platform because it provides neither `crypto.getRandomValues` nor Node.js' "crypto" module.

java.lang.UnsupportedOperationException: java.security.SecureRandom is not supported on this platform because it provides neither `crypto.getRandomValues` nor Node.js' "crypto" module.

A workaround is trying to avoid using UUID.newUUID() in Scala.js during testing with NodeJS and DOM

The underlying issue is that jsdom does not support the Web Crypto API:
jsdom/jsdom#1612

There are workarounds listed in that issue comments.

@sjrd Thanks! Good to know that. For now, I'll switch the implementation so as not to depend on UUID.newRandomUUID().
