Thanks for sharing. Just checked that evejs does a good job in providing the multi-agent communication layer.
Just FYI, Rxjs can simplify your logic in handling some practical complexities (such as throttle to filter duplicated messages, etc.)
For the agent communication, the actor model (eg. Akka ) were once very popular, now ReactiveX (eg. Rxjs mentioned above) is trending as well. You can find implementations for different languages (Java, Js, C#, …) in case you need to support different platforms with same framework.
