Up and Running with redux-observable

via egghead.io

Overview

Note: RxJS imports have changed since the publication of this course. Operators now must be passed into .pipe to be applied to an observable.
In this course we will begin with nothing more than an empty directory & a text editor. Through small, focussed lessons we’ll learn how to setup a React project that uses Redux for state management and redux-observable for asynchronous actions. We’ll see how ‘epics’ are registered and how they each receive a ‘stream’ of actions from the store.
With an understanding of how things work, we’ll move onto solving common problems such as Ajax cancellation, creating sequences of async actions, enabling code reuse through higher-order Observables and much more.

This course is outdated, view updated material here: Asynchronous State Management with redux-observable v1
