Angular NGRX Store: State Management for Reactive Applications

🧠 What is NGRX Store?

NGRX Store is a state management solution for Angular applications, built on top of Redux principles. It helps organize application state in a predictable way, making it easier to manage complex data flows.

✅ Key Features

• Centralized State: All application state is stored in a single place.
• Unidirectional Data Flow: Actions → Reducers → State updates.
• Immutability: State is never mutated directly.
• DevTools Integration: Debugging and time-travel features for development.

📚 How to Use NGRX Store

1. Install Dependencies

   npm install @ngrx/store @ngrx/effects
   

2. Define State Structure
   Use interfaces to describe your state.

   

3. Create Actions
   Actions are events that describe changes in the application.

   export const increment = createAction('[Counter] Increment');
   

   

4. Write Reducers
   Reducers update the state based on actions.

   const counterReducer = createReducer(0, on(increment, (state) => state + 1));
   

   

5. Integrate with Effects
   Effects handle side effects like API calls.

   

🚀 Why Use NGRX Store?

• Predictability: State changes are tracked and debuggable.
• Scalability: Easier to manage large applications.
• Consistency: Ensures single source of truth for data.
