This is so evident and takes so much time to be treated it's disappointing, I love vite but if my production site refreshes the page every minute because of a websocket it don't need, I can't disable it for some reasons and nothing gets done about it for months why bother.

[ctburenski]

This was unexpected behaviour for me - I had this occur when using codespaces, and the page continued to refresh when it was disabled.

I tried opening the port for HMR, but the port-forwarding on codespaces maps ports to subdomains, and I decided to develop locally instead of trying to find a way to tell Vite to use a completely different url or set up a reverse proxy just for HMR.

The websocket is used for more than just HMR, including showing error overlay from server and trigger full page reloads from plugins. Having server.hmr: false turn those off could be confusing (maybe not as destructive if we have docs). Otherwise perhaps #6090 might help here too.

This feature request seems to be requested to prevent the infinite reload problem.
I'm closing this issue because #9007 fixed that problem.
If there is other reasons, please create a new issue with the reason.
