React Without Redux vs With Redux
1. React Without Redux (Normal State Management)
In normal React, we use:
- useState
- useEffect
- props
Data Flow:
Parent → Child (via props) Child → Parent (via callbacks)
Problem: Prop drilling becomes messy in large apps.
App
└── Dashboard
└── Section
└── ProfileList
You must pass data through multiple levels unnecessarily.
2. React WITH Redux
Redux introduces a global store for managing state.
Data Flow:
Component → Dispatch Action → Redux Store → UI Updates
Any component can access data directly from the store.
3. Differences
State Location
- Without Redux: Inside components
- With Redux: Global store
Data Sharing
- Without Redux: Props drilling
- With Redux: Direct access via store
Complexity
- Without Redux: Simple apps
- With Redux: Large scalable apps
Performance
- Without Redux: Good for small apps
- With Redux: Better for complex apps
4. Real Project Example
Without Redux
- ProfileList fetches data
- ProfileForm updates list manually
- Props passed between components
With Redux
- ProfileForm dispatches action
- ProfileList reads from store
- UI updates automatically
5. When to Use Redux
- Large applications
- Shared state across many components
- Auth systems
- Search, filters, pagination
When NOT to use Redux
- Small apps
- Simple forms
- No shared state
React alone: Local state management
Redux: Global state manager for large applications
