🐛 Bug Report: Vite's HMR update is not working in docker compose on windows

[mustafa-sayyed]

📜 Description

When running the frontend with docker-compose-local.yaml on Windows, changes inside src are reflected in the mounted file system, but Vite does not restart or hot-reload. The dev server stays running and only picks up changes after a manual container restart

This is happening because the file system change events are not getting delivered from Windows to the Linux container
to Chokidar ( vite relies on chokidar for hmr update )

👟 Reproduction steps

1. compose up using docker-compose-local.yaml
2. Change something in the frontend src folder
3. Observe logs of Docker Compose

👍 Expected behavior

Editing any file in the src should trigger Vite HMR immediately
No manual container restart should be required

👎 Actual Behavior with Screenshots

This video shows that the changes are reflected in the mounted volume, but the Vite server is getting file change events, resulting in no HMR updates

Please assign it to me
The fix is simple: we have to use Chokidar's polling feature ( because Vite uses Chokidar to watch files )

Hey @dartpain Since this issue has been open for a few weeks and is blocking Windows users from utilizing HMR smoothly, I'd love to take it over.

I can implement the Chokidar polling fallback config in vite.config.ts controlled by an environment variable flag so it doesn't hurt CPU performance for non-Docker users. Could you please assign this to me? I can have a PR ready shortly!
