Redux and @ngrx

What is Redux?

Redux is an application state manager for JavaScript applications, and keepswith the core principles of the Flux-architecture by having a unidirectionaldata flow in your application.

Where Flux applications traditionally have multiple stores, Redux applicationshave only one global, read-only application state. This state is calculated by"reducing" over a collection or stream of actions that update it in controlled ways.

What is @ngrx?

Redux state managers have been very well received and have inspired the creation of @ngrx, a set of modules that implement the same way of managing state as well as some of the middleware and tools in the Redux ecosystem. @ngrx was created to be used specifically with Angular and RxJS, as it leans heavily on the observable paradigm.

We'll describe how to use this approach in an application.
