valtio-sync

valtio-sync saves Valtio state on the device and syncs it through your application's server endpoint.

Local changes are saved automatically. Your app calls sync() to send pending changes and fetch server changes. A pending change is called dirty until it is accepted or rejected by the server.

Use it to save one user's state across devices. It does not provide realtime collaboration.
