React Native State Management 2026: Zustand vs Redux vs TanStack Query

"Which state management should I use?" is still one of the most-asked React Native questions. The answer in 2026 is simpler than the number of libraries suggests, because most apps have two kinds of state, and each has a clear best tool.

First, split your state

• Server state is data that lives on a backend: products, posts, user profiles, orders. It needs caching, refetching, pagination, and invalidation.
• Client state is data that lives only in the app: theme, onboarding progress, cart drafts, which sheet is open, the current session.

Most "Redux is too complicated" pain came from putting server state in a client store and hand-writing loading flags and cache logic. Handle server state with a dedicated tool, and your client store becomes tiny.

TanStack Query: the default for server state

npx expo install @tanstack/react-query

// app/_layout.tsx
import { QueryClient, QueryClientProvider } from "@tanstack/react-query"
import { Stack } from "expo-router"

const queryClient = new QueryClient()

export default function RootLayout() {
  return (
    <QueryClientProvider client={queryClient}>
      <Stack />
    </QueryClientProvider>
  )
}

import { useQuery } from "@tanstack/react-query"

export function useProducts() {
  return useQuery({
    queryKey: ["products"],
    queryFn: () => fetch("https://api.example.com/products").then((r) => r.json()),
    staleTime: 60_000,
  })
}

// In a screen
const { data, isPending, error, refetch } = useProducts()

You get caching, deduplication, background refetch, retries, pagination (useInfiniteQuery), and optimistic updates without writing them yourself. Pair it with FlashList and pull-to-refresh and you have a production feed.

Zustand: the default for client state

npx expo install zustand

import { create } from "zustand"

type CartItem = { id: string; qty: number }

type CartState = {
  items: CartItem[]
  add: (id: string) => void
  clear: () => void
}

export const useCart = create<CartState>((set) => ({
  items: [],
  add: (id) =>
    set((s) => {
      const existing = s.items.find((i) => i.id === id)
      return existing
        ? { items: s.items.map((i) => (i.id === id ? { ...i, qty: i.qty + 1 } : i)) }
        : { items: [...s.items, { id, qty: 1 }] }
    }),
  clear: () => set({ items: [] }),
}))

// Subscribe to just what you need, so the component only re-renders when it changes
const count = useCart((s) => s.items.length)
const add = useCart((s) => s.add)

No provider, no reducers, and no actions file. It's about 1KB, works outside React (useCart.getState()), and persists easily with MMKV.

Redux Toolkit: structure for big teams

Modern Redux is Redux Toolkit (RTK), much less verbose than classic Redux:

import { configureStore, createSlice, type PayloadAction } from "@reduxjs/toolkit"

const sessionSlice = createSlice({
  name: "session",
  initialState: { userId: null as string | null },
  reducers: {
    signedIn: (state, action: PayloadAction<string>) => {
      state.userId = action.payload
    },
    signedOut: (state) => {
      state.userId = null
    },
  },
})

export const { signedIn, signedOut } = sessionSlice.actions
export const store = configureStore({ reducer: { session: sessionSlice.reducer } })

Pick RTK when you have many developers who benefit from enforced patterns, you need middleware (analytics, sync, undo), or you want RTK Query as an all-in-one server and client solution. Redux DevTools' time-travel debugging is still unmatched for complex flows.

Jotai: atomic state for fine-grained UI

Jotai models state as small atoms that components subscribe to individually:

import { atom, useAtom } from "jotai"

const filterAtom = atom<"all" | "active" | "done">("all")
const todosAtom = atom<Todo[]>([])
const visibleTodosAtom = atom((get) => {
  const filter = get(filterAtom)
  return get(todosAtom).filter((t) => filter === "all" || (filter === "done") === t.done)
})

const [filter, setFilter] = useAtom(filterAtom)

Pick Jotai when you have lots of interdependent, derived UI state (editors, builders, complex forms) and want React-like composition without selectors.

How to choose

• Small or medium app, most teams: TanStack Query + Zustand.
• Large team, strict conventions: Redux Toolkit + RTK Query.
• Heavy derived UI state: Jotai (+ TanStack Query for server data).
• Mostly server data, little global UI state: TanStack Query + useState and Context. You may not need a store at all.
• Offline-first or sync-heavy: look at a local database (expo-sqlite) as your source of truth and a reactive layer on top.

Recommended Expo stack for 2026

1. TanStack Query for anything fetched from an API.
2. Zustand for session, settings, and UI state.
3. MMKV to persist Zustand instantly (guide).
4. expo-secure-store for tokens (guide).
5. Expo Router params for navigation state. Don't duplicate it in a store.

Common mistakes to avoid

• Copying API data into Zustand or Redux "so it's global". Let TanStack Query own it.
• Subscribing to the entire store (useCart()) instead of selecting a slice, which causes extra re-renders.
• Storing derived values. Compute them with selectors or derived atoms.
• Putting secrets in a persisted store. Use SecureStore.
