Phoenix.Presence sends “presence_diff” events using
Phoenix.Channel.Server.local_broadcast/4
If someone is using a non-standard metadata when subscribing to the topic it’s not possible to specify a custom dispatcher module. It will always use the Phoenix.Channel.Server.dispatch/3 function.
Would it make sense to allow a :dispatcher option and use instead:
broadcast = %Broadcast{
topic: topic,
event: "presence_diff",
payload: presence_diff
}
Phoenix.PubSub.local_broadcast(state.pubsub_server, topic, broadcast, dispatcher)
where dispatcher defaults to Phoenix.Channel.Server
Thoughts?
