react-native上使用localStorage的redux初始状态问题

npm install @react-native-async-storage/async-storage

import AsyncStorage from '@react-native-async-storage/async-storage';

import AsyncStorage from '@react-native-async-storage/async-storage';

// 定义初始状态
const initialState = {
  // 初始状态的属性
};

// 创建reducer
const reducer = (state = initialState, action) => {
  switch (action.type) {
    // 处理其他action
    default:
      return state;
  }
};

// 获取之前存储的状态
AsyncStorage.getItem('reduxState')
  .then((storedState) => {
    if (storedState) {
      // 如果存在之前存储的状态，则将其作为初始状态
      initialState = JSON.parse(storedState);
    }
  })
  .catch((error) => {
    console.log('Error retrieving stored state:', error);
  });

export default reducer;

import AsyncStorage from '@react-native-async-storage/async-storage';
import { createStore } from 'redux';

// 创建store
const store = createStore(reducer);

// 订阅store的变化
store.subscribe(() => {
  // 获取最新的状态
  const state = store.getState();

  // 将状态存储到AsyncStorage中
  AsyncStorage.setItem('reduxState', JSON.stringify(state))
    .catch((error) => {
      console.log('Error storing state:', error);
    });
});
