在React中使用Redux类似于Pinia的本地存储方式,可以使用redux-persist库来实现。下面是一个示例代码:

首先,安装必要的依赖:

npm install redux redux-persist react-redux

接下来,创建一个Redux store,并配置redux-persist

// store.js
import { createStore } from 'redux';
import { persistStore, persistReducer } from 'redux-persist';
import storage from 'redux-persist/lib/storage'; // 默认使用localStorage作为存储引擎

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

// 定义reducer
const reducer = (state = initialState, action) => {
  // 处理action并更新状态
};

// 配置persist
const persistConfig = {
  key: 'root', // 存储键名
  storage, // 存储引擎
};

const persistedReducer = persistReducer(persistConfig, reducer);

// 创建store
const store = createStore(persistedReducer);
const persistor = persistStore(store);

export { store, persistor };

然后,在React组件中使用Redux store:

// App.js
import React from 'react';
import { Provider } from 'react-redux';
import { PersistGate } from 'redux-persist/integration/react';
import { store, persistor } from './store';

import MyComponent from './MyComponent';

const App = () => {
  return (
    <Provider store={store}>
      <PersistGate loading={null} persistor={persistor}>
        <MyComponent />
      </PersistGate>
    </Provider>
  );
};

export default App;

最后,在组件中使用Redux的状态和操作:

// MyComponent.js
import React from 'react';
import { useSelector, useDispatch } from 'react-redux';

const MyComponent = () => {
  const count = useSelector(state => state.count);
  const dispatch = useDispatch();

  const increment = () => {
    dispatch({ type: 'INCREMENT' });
  };

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={increment}>Increment</button>
    </div>
  );
};

export default MyComponent;

通过以上代码,你可以在React中使用Redux类似于Pinia的本地存储方式。Redux-persist会自动将Redux store的状态保存到本地存储中,并在应用启动时自动还原状态
