Redux Patterns: Best Practices for State Management 🧩

Redux is a predictable state container for JavaScript apps, widely used in React projects. Here are key patterns and principles to master:

🔑 Core Concepts

• Single Source of Truth: Store all state in an object tree within a single store
• State Immutability: Never mutate state directly (use immer or spread operators)
• Pure Functions: Reducers must be pure (no side effects, deterministic output)
• Actions: Describe what happened, not how to update state
• Middleware: Handle asynchronous operations and logging

📊 Common Patterns

1. Normalizing State
   • Use nested objects for related data
   • Example: entities.users instead of multiple top-level arrays
2. Feature-Sliced Design
   • Split reducers and actions by feature (e.g., authSlice, cartSlice)
3. Using Redux Toolkit
   • Simplifies Redux setup with createSlice and configureStore
   • Learn more about Redux Toolkit
4. Optimistic Updates
   • Assume actions will succeed before they're confirmed
5. Memoization
   • Use useSelector with reselect to optimize component re-renders

State_Management

🚀 Practical Tips

• Always use combineReducers for complex state structures
• Implement thunk for async operations
• Use immer to safely mutate state
• Keep action types in @actions folder for better organization
• Explore advanced patterns for deeper insights
