Introduction to NgRx Store
NgRx Store Essentials
This lesson introduces you to NgRx, a powerful state management solution for Angular applications.

What is NgRx?
NgRx is inspired by Redux and helps manage state centrally in Angular applications, simplifying data handling across components.
Why Use NgRx?
- Centralized state management
- Clear and predictable data flow
- Easier debugging and testing
Core Concepts
NgRx involves key concepts:
- Store: Holds application state
- Actions: Describe events
- Reducers: Handle state transitions
- Selectors: Retrieve state data
Installing NgRx Store
Install NgRx using npm:
npm install @ngrx/store --saveCreating a Store
Define the store in your application module:
StoreModule.forRoot({ appState: appReducer })Creating Actions
Actions define events in your application:
export const loadData = createAction('[App] Load Data');Reducers
Reducers handle state changes by responding to actions and producing new state:
export const appReducer = createReducer(
initialState,
on(loadData, state => ({ ...state, loading: true }))
);NgRx Store Summary
Summary
You've learned the essentials of using NgRx Store to manage your app state effectively. Well done!
