如何使用redux-toolkit配置redux-persist？

Question

我已经使用传统的react-redux设置配置了redux-persist，如下所示：

onst persistConfig = {
  key: 'root',
  storage,
  whitelist: ['todos'],
};

const persistedReducer = persistReducer(persistConfig, reducer);

const store = createStore(
  persistedReducer,
  window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()
);

const persistor = persistStore(store);

// wrapper
const StateProvider = ({ children }) => {
  return (
    <Provider store={store}>
      <PersistGate loading={<div>Loading...</div>} persistor={persistor}>
        {children}
      </PersistGate>
    </Provider>
  );
};

但是，如何使用redux-toolkit对其进行配置？到目前为止，我已经尝试过了：

const persistedReducer = persistReducer(persistConfig, todoreducer);
const store = configureStore({
  reducer: {
    todos: persistedReducer,
  },
});

const persistor = persistStore(store);

// wrapper
const StateProvider = ({ children }) => {
  return (
    <Provider store={store}>
      <PersistGate loading={<div>Loading...</div>} persistor={persistor}>
        {children}
      </PersistGate>
    </Provider>
  );
};

但是，它不起作用。我无法通过const todos = useSelector(state => state.todos);获取todos

它返回未定义的。

store.js

import {configureStore} from '@reduxjs/toolkit';
import storage from 'redux-persist/lib/storage'
import {combineReducers} from "redux"; 
import { persistReducer } from 'redux-persist'
import thunk from 'redux-thunk'

const reducers = combineReducers({
 //...            
});

const persistConfig = {
    key: 'root',
    storage
};

const persistedReducer = persistReducer(persistConfig, reducers);


const store = configureStore({
    reducer: persistedReducer,
    devTools: process.env.NODE_ENV !== 'production',
    middleware: [thunk]
});

export default store;

索引/App.js

import store from './app/store';
import { PersistGate } from 'redux-persist/integration/react'
import { persistStore } from 'redux-persist'

let persistor = persistStore(store);

    <Provider store={store}>
        <PersistGate loading={null} persistor={persistor}>
        <App/>
        </PersistGate>
    </Provider>,

现在在Redux Toolkit docs中有一个指南可以帮助你做到这一点，并提供清除持久化状态和使用RTK Query的建议。

它还包含一些代码，您可以复制和粘贴这些代码以忽略react-persist调度的操作类型。这将阻止它抛出错误消息(当我使用Expo运行我的React Native应用程序时，我得到了错误A non-serializable value was detected in an action, in the path: `register`. )。

在撰写本文时，他们的代码示例如下所示：

import { configureStore } from '@reduxjs/toolkit'
import {
  persistStore,
  persistReducer,
  FLUSH,
  REHYDRATE,
  PAUSE,
  PERSIST,
  PURGE,
  REGISTER,
} from 'redux-persist'
import storage from 'redux-persist/lib/storage'
import { PersistGate } from 'redux-persist/integration/react'

import App from './App'
import rootReducer from './reducers'

const persistConfig = {
  key: 'root',
  version: 1,
  storage,
}

const persistedReducer = persistReducer(persistConfig, rootReducer)

const store = configureStore({
  reducer: persistedReducer,
  middleware: (getDefaultMiddleware) =>
    getDefaultMiddleware({
      serializableCheck: {
        ignoredActions: [FLUSH, REHYDRATE, PAUSE, PERSIST, PURGE, REGISTER],
      },
    }),
})

let persistor = persistStore(store)

ReactDOM.render(
  <Provider store={store}>
    <PersistGate loading={null} persistor={persistor}>
      <App />
    </PersistGate>
  </Provider>,
  document.getElementById('root')
)

我刚刚用完全相似的设置尝试了一下，它似乎起作用了。如果有用的话，我在"@reduxjs/toolkit": "^1.4.0",，"redux-persist": "^6.0.0"和"react-redux": "^7.2.1"上。HTH。
