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 })

  };
