Redux

What is Redux?

A predictable state container for JavaScript applications, providing a centralized store for managing application state. Based on the Flux architecture pattern, Redux enforces unidirectional data flow and makes state changes predictable through pure functions called reducers. Features time-travel debugging, middleware support, and excellent DevTools integration. Widely adopted in large-scale React applications for complex state management.

When to use it

• Essential for managing complex application state in React applications, especially when state needs to be shared across many components.
• Ideal for applications with complex data flows, undo/redo functionality, and when you need to persist or log state changes.
• Commonly used in enterprise applications, dashboards, and data-heavy interfaces.
• Works seamlessly with React but can also be used with other frameworks.

When NOT to use it

• Small applications with simple state - React's built-in useState/useContext is sufficient
• When you only need local component state - Redux adds unnecessary complexity
• Projects with minimal shared state - prop drilling or Context API is simpler
• When team lacks Redux experience - consider Zustand or Jotai for simpler alternatives
