在React Native Fast Refresh(expo cli)中避免重置Redux状态的一个解决方法是将Redux状态保存在一个持久化存储中,例如AsyncStorage。
首先,安装redux-persist和redux-persist-expo-securestore库:
npm install redux-persist redux-persist-expo-securestore
然后,创建一个redux-persist的配置文件,例如persistConfig.js
:
import { AsyncStorage } from 'react-native';
import { createStore } from 'redux';
import { persistReducer, persistStore } from 'redux-persist';
import expoSecureStore from 'redux-persist-expo-securestore';
import rootReducer from './reducers';
const persistConfig = {
key: 'root',
storage: expoSecureStore,
};
const persistedReducer = persistReducer(persistConfig, rootReducer);
export const store = createStore(persistedReducer);
export const persistor = persistStore(store);
在上述配置文件中,我们使用了redux-persist-expo-securestore
作为存储引擎,它使用Expo SecureStore模块来安全地存储Redux状态。
然后,在主应用文件中(例如App.js
),将Redux Provider组件包裹在PersistGate组件中,以确保Redux状态被持久化和恢复:
import React from 'react';
import { Provider } from 'react-redux';
import { PersistGate } from 'redux-persist/integration/react';
import { store, persistor } from './persistConfig';
import AppContainer from './AppContainer';
export default function App() {
return (
);
}
现在,当你在React Native Fast Refresh中重新加载应用程序时,Redux状态将被恢复到上一次持久化的状态,而不会被重置。
