Difference Between Flux and Redux

 

Flux and Redux are both state management architectures for JavaScript applications, especially React, but they have important differences in terms of complexity, approach, and use cases. Let's dive into a comparison.

Feature	Flux	Redux
Architecture	Unidirectional data flow with multiple stores and a dispatcher.	Unidirectional data flow with a single global store.
Stores	Multiple stores, each managing a part of the app's state.	Single store managing the entire app's state tree.
Dispatcher	Central dispatcher to handle action distribution to stores.	No dispatcher; actions are sent directly to reducers.
State Management	Each store has its own state, which can lead to complexity.	Single source of truth for the entire app state.
Reducers	Stores update state directly based on actions received.	Pure functions (reducers) define how the state updates.
Middleware	No native support for middleware.	Supports middleware for handling side effects (e.g., redux-thunk, redux-saga).
Action Handling	The dispatcher sends actions to stores.	Actions dispatched directly to the reducer.
Immutability	Not enforced by default, stores can modify the state directly.	Emphasizes immutability with reducers returning new state.
Ease of Debugging	Harder to trace changes due to multiple stores.	Easier to debug with a single state tree and tools like Redux DevTools.
Learning Curve	Steeper due to multiple stores and dispatcher interaction.	Easier, especially with Redux Toolkit simplifying setup.

Summary

• Flux allows for more flexibility with multiple stores but can become complex as your app scales.
  
  
• Redux simplifies the architecture by centralizing the state into a single store, with reducers managing state changes and excellent tooling for debugging.
