The issue is that the Plan 9 server in WSL 2 does not support file watching on Windows files. The workaround is to place your files into the Linux file system (plus you'll get a performance boost).

see microsoft/WSL#4739

Probably nice to put in the docs somewhere. I was wondering why the example in the docs that I was trying doesn't work at all.

Thank you! Solved for me.

I can confirm it doesn't work on Windows folders.

I tried the following example provided in the official documentation: https://bun.sh/docs/runtime/hot#:~:text=In%20this%20example%2C%20Bun%20is

import { serve } from "bun";
console.log("I restarted at:", Date.now());

serve({
  port: 4003,

  fetch(request) {
    return new Response("Sup");
  },
});

The page makes no mention of Windows, WSL, folder, dir, issue, and it doesn't have any sort of a warning for Windows users.

For any Windows users reading this, currently you need to place your projects somewhere in the folder \\wsl$, I choose to place my projects in \\wsl.localhost\Ubuntu\home\USER\dev.
