How do you manage state in Angular with NgRx?

Short answer: NgRx is a Redux-inspired state management library for Angular. Uses Actions, Reducers, Store, and Effects to handle application state predictably. Centralizes state for easy debugging, time-travel, and immutability. Ideal for complex apps requiring consistent global state management.

Real-world example (ShopNest)

ShopNest admin can be built in Angular with modules/components, services for API calls, and reactive forms for product edit.

2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
