state-management-patterns

Local state in React is managed within a component using useState or useReducer, while global state is shared across components using Context, Zustand, Redux Toolkit, or Jotai. This distinction determines data flow and component reusability in React applications.

Use React Query or SWR for server state management to handle fetching, caching, and synchronizing remote data. Redux Toolkit is better suited for managing complex client-side global state, ensuring a single source of truth for application-specific data.

To avoid unnecessary re-renders with React Context, apply performance optimization techniques such as state colocation, splitting contexts by state frequency, and selecting specific state slices to ensure components only update when relevant data changes.

The best way to structure state hierarchy in a React dashboard is by categorizing needs: use useState for local inputs, useContext for themes, and global stores like Zustand for shared data grids, adhering to single source of truth principles.

Zustand provides a centralized global store approach suitable for managing shared data grids, whereas Jotai utilizes an atomic state model. Both manage global state effectively, but Zustand aligns closer to traditional single source of truth patterns.
