Does not work on node 17 or above, requires node 16

[Charuru]

Seems like this is known? f78b1b5

Is there any plan to fix this or is it just stuck on 16 forever?

No, it just means that 16 was most recent at the time of writing. Is there something not working on 17+?

Oh okay, 17&18 was out at that time so I assumed. Just doesn't start for me on 16+ and there are other reports on google.

Also what do you think about converting this to happy-dom instead?

@badeball from what I see then callback never happens.

      jsdom.JSDOM.fromURL(url, jsdomOptions).then(function (dom) {
        self.window = dom.window;
      });

This might be of interest to you.

Can you try running tests with NODE_OPTIONS=--dns-result-order=ipv4first ..?

Also what do you think about converting this to happy-dom instead?

I think a happy-dom integration should exist as a separate package.

[Charuru]

That does fix it, are you able to use 16+ without that option?

[badeball]

It's a bit up to you. You can either run your app and have it listen on both ipv4 and ipv6, in which case all node versions are going to work or you have to tell node and jsdom what you mean when you ask it to access "localhost". You can change the default from the runtime like so:

import dns from "node:dns";
dns.setDefaultResultOrder("ipv4first");

[badeball]

Wait, karma is the app in this context (I forget what repo I am in..). Maybe we can make some assumptions about it. Leaving this open for now.

[Charuru]

I don't understand, where do I do this? Shouldn't it be handled by the launcher?

Other launchers like ChromeCanaryHeadless that I'm also using works fine without any changes.
