Class ApplicationBadgeWebSocketService

java.lang.Object

io.meeds.appcenter.service.ApplicationBadgeWebSocketService

@Service
public class ApplicationBadgeWebSocketService
extends Object

Notifies a browser that one of its badges changed.

The channel is push-only: nothing is ever read from it, so the client-controlled-input trust boundary that an inbound handler would have to guard simply does not exist here. The frame carries the badge name only, never the count — the browser has to re-fetch through the authenticated REST endpoint, where the ACL is applied again.
