npm ws package overridden by broken baked-in module

[thislooksfun]

What version of Bun is running?

0.6.2

What platform is your computer?

Darwin 22.4.0 x86_64 i386

What steps can reproduce the bug?

Here is a minimal example file:

import WebSocket from "ws";

const wss = new WebSocket.Server({ port: 3000 });

wss.on("connection", ws => {
  console.log("connection");
  ws.send("Hello world");
  ws.close();
});

wss.on("listening", () => {
  console.log("listening");
});

console.log("Started WebSocket server (?)");

When this file is run with Node it requires that the ws package is installed, and when it is run it outputs

Started WebSocket server (?)
listening

And attempts to connect to it succeed.

Running the same file with Bun works even without the ws package installed, and produces the output

Started WebSocket server (?)

And it does not accept any connections.

What is the expected behavior?

I would expect that if I install the ws package then Bun should use the ws package, and if it is going to override that then the replacement should at least be compatible and functional.

What do you see instead?

No response

Additional information

Yes I know that Bun.serve can do websockets, but I'm trying to use a different package that itself uses ws under the hood, and I don't want to have to rewrite that whole package just to make it work with Bun's idiosyncrasies.

I see there is a PR up to fix this, but is there any way I can work around this in the meantime? Is there any way for me to tell Bun to just load the ws package from node_modules instead of using the built-in version?

@Jarred-Sumner @cirospaciari I just updated from 0.6.2 to v0.6.3 and it's still broken. Running the above code in Node produces a stable WebSocket server that I can connect to. Running the same code in Bun 0.6.3 logs "Started WebSocket server (?)" and immediately exits. Even if I introduce an artificial delay to keep it from exiting (setTimeout(() => {}, 60_000)) it still never logs "listening" or "connection", and attempts to connect with a client fail with WebSocket connection to 'ws://<address>:<port>/' failed: There was a bad response from the server.

Is there really no way I can just use the ws package from node_modules? Why is Bun overriding this 3rd-party package anyway?

Due to the missing exports for ping/pong in Bun.serve i tried to use ws as fallback until Bun.serve is fixed.
I am using Bun 0.6.13 on Darwin 22.5.0 x86_64 i386 and this problem still persists.
