createWebSocketStream in `ws` package not implemented

[sapter]

What version of Bun is running?

0.8.1+16b4bf341acc0f4804f0b6bdf5298c180cd00366

What platform is your computer?

Darwin 22.5.0 arm64 arm

What steps can reproduce the bug?

The createWebSocketStream method from the ws package breaks. Users get a Not supported yet in Bun error when trying to use it.

import WebSocket, { createWebSocketStream } from "ws";

{...}

const s = new WebSocket(this.env.SOCKET_URL);
// The line below breaks in Bun :=(
const duplex: Duplex = createWebSocketStream(s, { decodeStrings: false }); 

What is the expected behavior?

The createWebSocketStream works

What do you see instead?

Not supported yet in Bun error

Additional information

Looks like Bun overwrites the ws package. But not all methods in that package have been implemented leaving many users unable to use the package.

I'm also really looking forward to using the ws support. Specifically my use case is utilizing mqtt.

Same here. Use case prisma pulse https://www.prisma.io/docs/data-platform/pulse/what-is-pulse

[sorenbs]

We would like for Prisma Pulse to support Bun. Is there a way we can help get this prioritised?

I think this is resolved with version 1.1 :D

Just got the opportunity to try this out today and unfortunately it doesn't seem like mqtt.js is working.
