RHub - Reactive Event Hub

JavaDocs

Build Status Android Arsenal

Reactive Hub is a collection of multi-receiver and multi-producer Proxies connecting Publishers and Subscribers so that Subscribers can receive events without knowledge of which Publishers, if any, there are, while maintaining easily identifiable connection between them.

It is ideal for centralizing cross-cutting activities like UI updates, logging, alerting, monitoring, security, etc.

Motivation

  • Simplified combination of Pub/Sub (EventBus) pattern and Reactive Programming
  • Most 'Rx-EventBuses' implementations support only non Rx input/output of events
  • In Standard EventBus the link between producers and event consumers is not that evident thus making the code more difficult to follow, reason and debug

Example

	RxHub rxHub = new DefaultRxJava1Hub();
	rxHub.getPub("src1").subscribe(System.out::println);
	rxHub.addUpstream("src1", Observable.just(1));
	rxHub.addUpstream("src1", Observable.just(5));
	rxHub.getPub("src1").subscribe(System.err::println);

Overview

RHub

RHub allows Publish/Subscribe pattern implementation and thus helps decouple components. This can be compared to an EventBus where:

  • publishing events may happen via single post using 'emit()' or by adding a Publisher
  • RHub Proxies take care of connecting publishers and consumers to the Hub
  • The subscriptions and the flow of events is handled by the Reactive Framework (RxJava, Reactor, etc.)

In RHub different set of events are separated into Proxies identified by a Tag(topic).

  • a Hub contains Proxies which can merge inputs from 0-n Publishers and post to 0-n Subscribers
  • a Proxy is identified by a Tag
  • a single event from non-rx code can be emitted on a Proxy
