Example Usage

Here’s a basic setup of how to use expo-zustand-persist to persist your store:

import { create } from 'zustand';
import { persist } from 'expo-zustand-persist';
import AsynStorage from '@react-native-async-storage/async-storage';

// Define your store as usual
const useStore = create(
  persist(
    (set) => ({
      counter: 0,
      increase: () => set((state) => ({ counter: state.counter + 1 })),
      reset: () => set({ counter: 0 }),
    }),
    {
      name: 'my-app-storage', // unique name for storage key
            storage: createJSONStorage(() => AsynStorage), // Using WmaStorage as the storage engine
    }
  )
);
