## What it is
NgRx is a collection of reactive state management libraries for Angular applications, including the Redux-style Global Store and the modern SignalStore. It is built on RxJS observables and Angular signals to manage application state predictably.

## Use cases
- manage global state in an angular app
- redux-style store for angular
- angular signal-based state management
- reactive state with rxjs observables
- share state across angular components
- predictable state container for angular

## When to choose
- you are building medium-to-large Angular applications with complex shared state
- you want a Redux-pattern store or signal-based store tightly integrated with Angular
- your team wants a mature, well-documented ecosystem with strong community support

## When to avoid
- you are not using Angular
- your app is small and simple component-local state suffices
- you want a framework-agnostic state library

## Facets
- artifact type: library
- maturity: stable
- function: state-management, frontend-framework
- domain: frontend, web-development, developer-tools
- platform: cross-platform
- tags: angular, rxjs, redux-pattern, signals, observables, typescript, web-server, nodejs
