As your Angular application grows and becomes more complex, you need a consistent way of describing and controlling application flows. NgRx is a reactive framework for managing state and side effects in your Angular application. NgRx allows you to decrease responsibility of your components, isolate interactions with external APIs, and organize your application into smaller modules of code. We'll look at using state management with common patterns, practices that help you scale up your application, and how to keep your state management infrastructure manageable.
