从应用商店或 Play 商店更新时应用崩溃，因为它有旧的本地存储

Question

我已经使用 redux-persist 将数据持久化到 redux 存储。我现在在商店中添加了一些新标志，但是当应用程序从商店更新时，它不会获得新标志，因为它具有旧的本地存储，并且本地存储在更新应用程序时不会清除。这会导致应用程序崩溃，直到我删除它后重新安装该应用程序。

'use strict';

/* React Native */

import { AsyncStorage } from 'react-native';

/* Officetrax */

import { createStore, applyMiddleware } from 'redux';

import app from './reducers';

/* Thunk */

import thunk from 'redux-thunk';

/* Redux Storage */

import excludeSaveActionConstants from './constants/excludeSaveActionConstants';

/* Remote Redux Dev Tools */

import { composeWithDevTools } from 'remote-redux-devtools';

/* Redux Offline */

import { offline } from '@redux-offline/redux-offline';

import offlineConfig from '@redux-offline/redux-offline/lib/defaults';

/* Redux Logger */

import { createLogger } from 'redux-logger';

export default function configureStore() {

    // Create redux logger

    const logger = createLogger({

        //logger: remoteConsole,

        logErrors: true,

    });

    let persistOptions = { ...offlineConfig, whitelist: excludeSaveActionConstants };

    const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || composeWithDevTools;

    // Create the store with middleware applied

    let store = createStore(app, composeEnhancers(

        applyMiddleware(thunk),

        offline(persistOptions)

    ));

    return store;

}

如果您正在更改减速器结构，您应该迁移，或者按照 Jesse Schokker 的建议清除所有缓存，但如果您真的不想丢失其中的一些数据，那么请进行迁移。import { createMigrate } from 'redux-persist';const migrations = {    2: state => {      const { yourReducer } = state;      const mynewStructure = { ...yourReducer, myNewKey: 'some value' };       state.yourReducer = mynewStructure;      return state;      };    }  };  const persistConfig = {    ...offlineConfig,     whitelist: excludeSaveActionConstants    version: 2, // Add a version which will correspond to the number declared in your migrate    migrate: createMigrate(migrations, { debug: false })  };
