This repository contains CQRS application using node/express, servicebus-* + rabbitmq mongo and docker (swarm cluster included)

TODO: not yet finished...

(ui update data) >> [produce command] >> [handle rabbit event] >> [save data into eventstore mongodb (master node)] ... eventual consistency ... (ui fetch data) >> | pooling | websockets | backpreassure [query view / projection] >> [get data from mongodb (replica node)]
