Redux vs. Flux — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on April 16, 2024
Redux centralizes application state management in a single store, streamlining data flow; Flux uses multiple stores, allowing more flexibility but increasing complexity.

Key Differences
Redux adopts a single-store architecture where all application state is centralized, making state management predictable and consistent. In contrast, Flux utilizes multiple stores, each managing a specific domain of the app’s state, which can lead to more tailored but complex state management strategies.
While Redux relies on immutable state and pure functions to ensure predictability and facilitate debugging, Flux allows stores to handle their own logic, which can sometimes result in more dynamic but harder-to-track changes.
Redux enforces a strict unidirectional data flow where actions are dispatched, leading to state updates via reducers, which then update the UI. On the other hand, Flux has a more flexible dispatch mechanism, where actions can update multiple stores, and changes propagate through event listeners.
In Redux, all changes must pass through the reducer functions, ensuring that state transitions are easy to track and replay. Flux, however, uses a broadcast mechanism from stores after updates, which can complicate understanding the exact flow of data.
Redux provides powerful developer tools such as time-travel debugging due to its predictable state changes and centralized store. Whereas Flux, with its multiple stores and listener-based updates, often lacks similarly robust tooling support.
