Problem with Bun Websocket Adapter

[ValentinKolb]

WebSocket messages received as "[object Blob]" string in dev mode

When sending WebSocket messages in dev mode, the server receives the literal string "[object Blob]" instead of the actual message content.

Steps to reproduce:

// Client code
const socket = new WebSocket('ws://localhost:4321/api/ws');
socket.onopen = () => {
  socket.send("foo"); 
};

// Server receives: "[object Blob]" 
// Expected: "foo"

Environment:

• Using bunx to run dev server
• astro-bun-websocket with gratelets/bun-websocket package
• Dev mode uses ws package under the hood

The issue appears to be related to how the dev middleware handles message conversion when the underlying ws package receives data. The data seems to be incorrectly converted to string, resulting in the default JavaScript object toString representation.

Has anyone else encountered this issue?

Thanks for reporting! The bun adapter needs to updated anyway. I'll look into it later this week.

Thanks you!

I had less time to spare than I expected last week, but this is still on my radar.

[ValentinKolb]

No worries, take your time! Should I open an issue to track this, or is the discussion here fine?

[lilnasy]

Thanks! Yes, an issue would be helpful.

Done, I also created one regarding the question if the ws package is even necessary in dev mode. ( #165 )
