What is the difference between NgRx and Redux?

Inspired by Redux, NgRx provides a way to maintain data in your Angular application as a single source of truth . NgRx uses streams to interact with a data store. This data store connects to your components and services, and ultimately simplifies the entire process of data management in your Angular application.

NGXS is a state management pattern + library for Angular . It acts as a single source of truth for your application’s state, providing simple rules for predictable state mutations.

Ngrx is a group of Angular libraries for reactive extensions. Ngrx/Store implements the Redux pattern using the well-known RxJS observables of Angular 2 .
