我正在尝试将redux-persist与wix react-native-navigation集成。但是,我无法找到任何说明集成两个库所需的样板代码的示例或文档。
我想知道是否有人想要分享他们的解决方案,如果他们已经解决了这个问题?

首先,基本设置应与store.js
中in the documentation所述的反应原生导航相似或不相似:
import { persistStore, persistCombineReducers } from 'redux-persist'
import storage from 'redux-persist/es/storage' // default:
localStorage if web, AsyncStorage if react-native
import reducers from './reducers' // where reducers is an object of
reducers
const config = {
key: 'root',
storage,
}
const reducer = persistCombineReducers(config, reducers)
function configureStore () {
// ...
let store = createStore(reducer)
return store
// We'll skip persistStore for now
// let persistor = persistStore(store)
//return { persistor, store }
}
persistStore
来电被注释掉,因为我们将在下面进行此操作。 persistStore
方法在其第三个参数中进行回调。在恢复/重新水化状态后执行回调。这很好,因为这意味着我们可以延迟启动屏幕直到状态再水化。
假设您在App.js中有以下引导代码:
store = configureStore()
registerScreens(store, Provider)
Navigation.startTabBasedApp({
tabs: [{...},]
})
现在我们可以添加persistStore并将引导代码包装在其中:
store = configureStore()
persistStore(store, null, () => {
registerScreens(store, Provider)
Navigation.startTabBasedApp({
tabs: [{...},]
})
})
注意:
在第4版中,您传递 config 而不是 null :persistStore(store, config, callback)

如果要与App.js中的react-native-navigation v2集成,请确保在persistStore()
内调用registerAppLaunchedListener()
:
import { persistStore } from 'redux-persist';
...
Navigation.events().registerAppLaunchedListener(() => {
persistStore(store, null, () => {
Navigation.registerComponentWithRedux(...);
...
Navigation.setRoot({...})
...
})
})

在他的解决方案中,您还可以使用subscription()来检查您的用户是否仍在登录。这样,如果他们完全关闭了该应用程序,则无需再次登录(对于具有登录系统的用户)而且由于只有在存储持久后才调用它,因此您可以在选中此选项后启动您的应用。
import {Platform, AsyncStorage, AppState} from "react-native"
import {Navigation} from "react-native-navigation"
import {registerScreens} from "./routes"
import {Provider} from "react-redux"
import configureStore from "./stores/reduxStore"
import {Component} from "react"
const storage = configureStore()
registerScreens(Provider, storage.store)
let startapp = screen => {
Navigation.startSingleScreenApp({
screen: {
screen, // unique ID registered with Navigation.registerScreen
navigatorStyle: {
navBarHidden: true,
statusBarHidden: false,
statusBarColor: "white",
statusBarTextColorScheme: "dark"
}, // override the navigator style for the screen, see "Styling the navigator" below (optional)
navigatorButtons: {} // override the nav buttons for the screen, see "Adding buttons to the navigator" below (optional)
},
drawer: {
left: {
screen: "Drawer", // unique ID registered with Navigation.registerScreen
passProps: {} // simple serializable object that will pass as props to all top screens (optional)
}
},
tabsStyle: {
// optional, add this if you want to style the tab bar beyond the defaults
tabBarButtonColor: "#ffff00", // optional, change the color of the tab icons and text (also unselected). On Android, add this to appStyle
tabBarSelectedButtonColor: "#ff9900", // optional, change the color of the selected tab icon and text (only selected). On Android, add this to appStyle
tabBarBackgroundColor: "#551A8B", // optional, change the background color of the tab bar
initialTabIndex: 1 // optional, the default selected bottom tab. Default: 0. On Android, add this to appStyle
},
appStyle: {
orientation: "portrait"
}
})
}
storage.persistor.subscribe(() => {
storage.store.getState().user.logged
? startapp("mainscreen")
: startapp("loginscreen")
})

我们实际上不需要redux-persist。我们可以使用以下方法创建自己的redux-persist:
redux + store.subscribe(handlechange)
handleChange
函数将在我们商店中发生任何更改时运行。
还使用aync-await(promise)
不会阻塞主执行线程。
因此在内部创建商店中添加如下内容:
store.subscribe(async ()=>{
try {
await AsyncStorage.setItem("store", JSON.stringify(store.getState()));
} catch (error) {
// Error
}
})
然后在App.js(第一个要加载的组件)中。使用AsyncStorage.getItem('store')
。然后在应用启动之前更新商店。
localstorage
是一个同步功能,该功能阻止主线程。
AsynsStorage
不会阻塞主线程。
