State Management in React: Redux, Zustand, and Context
When to use global state, and how Redux Toolkit, Zustand, and Context compare for real-world React apps.
Choosing the right state approach keeps your React app maintainable. Here’s how global state tools stack up.

Options compared
Context — Built-in. Good for theme, auth, or narrow trees. Avoid one huge context for “everything”; it causes broad re-renders.
Redux Toolkit — Predictable global state, DevTools, middleware. Best when you have complex flows, time-travel debugging needs, or a team used to Redux.
Zustand — Minimal API, no providers, good with React. Great for moderate global state (auth, UI prefs, cart) without boilerplate.
Server state (TanStack Query, SWR) — Server data is not “global UI state.” Use a data-fetching library and keep client state separate.

Recommendation
Start with local state and Context for a few app-wide values. Add Zustand or Redux when you have real global state (many components, complex updates). Use TanStack Query (or similar) for server data.

Takeaway
Don’t default to Redux for every project. Match the tool to the problem: Context for little, Zustand for simple global state, Redux when you need strict structure and tooling.
