What is Redux?
Turkish: Redux
Redux centralizes application state in a store and makes changes traceable through an action and reducer flow, mostly in React apps.
What is Redux?
Redux is a state management library that keeps interface state in a single store and records changes through explicit events. It is best known in the React ecosystem, although the same model can be used outside React.
Redux is often unnecessary for a small form or a simple page. It becomes useful when an application has many screens, complex permissions, shared data, and a recurring need to answer: “where did this value change?”
How Does Redux Work?
Redux follows a one-way data flow:
- The UI or a service dispatches an action.
- A reducer receives the current state and the action, then returns the next state.
- The store keeps the updated state.
- Components subscribed to that state render again.
Reducers are expected to be pure functions: the same input should produce the same output. Side effects such as API calls are usually handled through thunks or middleware, especially when using Redux Toolkit.
When is Redux Useful?
Redux fits large admin panels, order flows, complex filters, and offline/online synchronization where many components read or update the same state. Action logs, predictable update rules, and time-travel debugging can make defects easier to isolate.
For smaller applications, Zustand, React Context, or local component state may be simpler. The right choice depends on state complexity, team habits, and how much debugging structure the product needs.
