How to deal with something like UncaughtException?

[XadillaX]

For exceptions from Promise, we can simply use unhandledrejection. But how about exceptions that not come from Promise? Is there any way to specify the behavior?

Can you give some examples of exceptions that do not come from Promise?

function test() {
  throw new Error('hello');
}

test();

maybe use something like

addEventListener('error', fn)

That would imply, in a browser, an "error" event on the document, I think. Do browsers have an event for this?

ah ok, so then it’s already an event on the global - that seems like something that should come for free with event emitters?

I think yes.

Not only for this event. I think we shoud collect and specify all available events in globalScope of Winter.

e.g. install / activate / unhandedrejection / error, etc.

In general, I think it's better (standards wise for new platforms) to use onerror/onunhandledrejection and not Node's uncaughtException/unhandledRejection/rejectionHandled hooks (and not ship EventEmitter) but mostly: I don't think it makes a ton of sense to standardize given the different error handling model.

Since we're discussing error event, I think ErrorEvent should be added into Common Minium API.

I don't think Node.js is interested in this if we're not shipping globalThis.addEventListener("error" which we are currently not and have no plans to as far as I can tell.

Also, Deno for example does something different from browsers (fires "error" for unhandled rejections).
