Sorry, I should have been clearer. I don't mean "does Deepstream tell the user when it's disconnected", I mean:
Does the Deepstream client have a facility (like Firebase) to instruct the remote server to perform an action in the event the client disconnects in the future and the client is unable to get any further message to the server?
ehm...this is not Horizon. But its a good question none the less. No, it does currently not have that facility, but it would certainly be a good addition
It's very hard to correctly manage distributed state without a guarantee similar to this.
