In this post I will describe the flow of actions through a Redux application configured with redux-observable middleware. In a Redux application, actions are dispatched and reduced synchronously, which makes it relatively straightforward to follow. However with redux-observable epics, we can introduces asynchronicity into the action flow when actions are dispatched as a result of asynchronous events. In this post we will look at what happens when a redux-observable epic emits a sequence of actions ([1,2,3]), and those actions in turn trigger epics that emit more actions (eg.
