Any plans to add async iterator support to IncomingMessage?

[hbgl]

Node's http.IncomingMessage inherits from stream.Readable which implements the async iterator protocol in recent versions of Node. It would be appropriate for the mock to also have support for it. A use case would be converting an http.IncomingMessage to a web Request:

import { IncomingMessage } from 'http';

function incomingMessageToRequest(incomingMessage: IncomingMessage) {
    return new Request('...', {
        method: '...',
        body: incomingMessage, // Body supports any async iterable
        duplex: 'half',
    });
}

It would help me fix this issue in Astro: withastro/astro#7525 (comment)

Hi @hbgl, there are no plans to implement this feature.

So I'd like encourage you to create a PR wow add a missing functionality.

Hello @eugef, thanks for the reply. I will create a PR for this new feature once I am done. It will require Node version >= 10 because that is when async iterator support was added.

As an aside, I would not give up on properly extending from ReadableStream (old PR) which already comes with async iterator support baked in among other things. One could even think about extending IncomingMessage directly. In any case, it would probably be a breaking change.

We are currently supporting Node.js 14 and above, so you can safely use async iterators

I saw this line in the package.json

node-mocks-http/package.json

Lines 40 to 42 in 5d97424

	"engines": {
	"node": ">=0.6"
	},

So I was unsure if adding async iterators would be a problem. Thanks for clearing that up.

Thanks for pointing out, I will fix it straight away
