The modern guide to React state patterns

State management in React is essential for creating dynamic and interactive applications, with several built-in and third-party options available in 2023. React's native tools, such as the useState, useReducer, and useContext Hooks, provide basic mechanisms for managing component-specific or shared states without prop drilling. For more complex state management needs, third-party libraries such as Redux, MobX, Recoil, Jotai, and Signia offer diverse paradigms, including global state management, observables, atomic state management, and signals. Redux remains popular for its extensive ecosystem and tooling, while MobX focuses on automatic state derivation. Recoil and Jotai introduce atomic state management, allowing components to subscribe to specific state pieces, and Signia uses reactive signals for state updates. State machines, facilitated by libraries like XState, provide an alternative approach, offering structured state transitions and the ability to handle parallel and hierarchical states. These varied approaches enable developers to choose the most suitable state management strategy for their specific project requirements.
