State Management in React Native: Context vs Zustand vs Redux Toolkit

The Problem

As your React Native app grows, passing props through 4-5 component levels becomes painful. You need a state management strategy � but which one?

Option 1: React Context + useReducer

Built into React. Zero dependencies. Great for low-frequency updates like theme, auth state, or user preferences.

const AuthContext = createContext(null);

export function AuthProvider({ children }) {
  const [state, dispatch] = useReducer(authReducer, initialState);
  return (
    <AuthContext.Provider value={{ state, dispatch }}>
      {children}
    </AuthContext.Provider>
  );
}

Avoid for high-frequency updates � every context change re-renders all consumers.

Option 2: Zustand

Lightweight (1 KB), simple API, no boilerplate. Perfect for most apps.

import { create } from 'zustand';

export const useCartStore = create((set) => ({
  items: [],
  addItem: (item) => set((s) => ({ items: [...s.items, item] })),
  clearCart: () => set({ items: [] }),
}));

Consume it anywhere � no Provider needed.

Option 3: Redux Toolkit

The industry standard for large, complex apps with many developers. More boilerplate, but excellent DevTools, middleware support, and predictable patterns.

Use RTK when you have a large team, complex async flows, or need time-travel debugging.

My Recommendation

| App size | Pick | |---|---| | Small / prototype | React Context | | Medium / production | Zustand | | Large / multi-team | Redux Toolkit |

For most apps, Zustand hits the sweet spot between simplicity and power.
