State Management in 2026: Redux vs Context vs TanStack Query

#react #reactnative #redux #nextjs

State management in React (and React Native) is clearer than ever in 2026. Here’s how I use Redux, Context, and TanStack Query now, and when I pick each.

TanStack Query — Server State First

Use for: Anything that comes from the server: API data, lists, details, pagination, and background refetching.

TanStack Query handles loading, error, caching, refetching, and invalidation. I keep server data in the query cache and avoid duplicating it in Redux or Context unless there is a strong product reason (for example, special offline behavior).

const { data, isLoading, error } = useQuery({
  queryKey: ['user', userId],
  queryFn: () => fetchUser(userId),
});
Enter fullscreen mode Exit fullscreen mode

When I use it in 2026: For nearly all async/server data. It reduces boilerplate, keeps fetching logic consistent, and scales well in both React and React Native.

Context — Global UI and App Config

Use for: Theme, locale, auth session reference, feature flags, and dependency providers.

Context is best for small, stable, read-heavy global values. Keep provider values minimal and memoized so you avoid unnecessary tree-wide re-renders.

When I use it in 2026: When state is simple and widely shared. If updates become frequent or logic gets complex, I move to a dedicated store.

Redux Toolkit — Complex Client State

Use for: Complex client state: multi-step flows, editor-like UIs, undo/redo, persistence, and strict state transitions.

Redux Toolkit keeps Redux practical with slices and solid conventions. I use it when:

  • The app has a lot of interdependent client state (wizards, dashboards, editors).
  • I need deterministic flows and explicit actions for debugging.
  • I need persistence/rehydration and predictable transitions across screens.
  • The team is already comfortable with Redux and the project size justifies it.

When I avoid it: For simple apps or when most data is server-driven. In those cases, TanStack Query + Context + local state is usually enough.

Quick 2026 Decision Rule

  • Server state (API-backed) -> TanStack Query
  • Global app config (theme/locale/session ref) -> Context
  • Complex client workflows (wizards/editors/undo) -> Redux Toolkit
  • Component-only UI state (modal open/input value) -> useState

How They Coexist in Real Projects

  • TanStack Query for server/cache state.
  • Context for app-wide configuration and providers.
  • Redux Toolkit only where client state is complex enough to justify it.
  • useState for local UI concerns.

I avoid “one tool for everything.” In 2026, the cleanest setups separate state by purpose: server data in query cache, shared config in Context, and complex client workflows in a store. That split keeps code easier to debug and faster to scale.
