Redux

redux.js.org

Predictable state container for JavaScript apps with a single immutable store.

Overview

Redux is a JavaScript library designed to help developers write applications with predictable and maintainable global state management. It centralizes your application's state and logic, enabling powerful capabilities like undo/redo, state persistence, and comprehensive debugging.

The library works with any UI layer and has a large ecosystem of addons. Redux's architecture provides excellent developer experience through the Redux DevTools, which enable time-travel debugging, state change tracing, and error reporting. It's designed to run consistently across different environments including client, server, and native applications.
