Real navigation and recovery

Question

I am trying to integrate redux-persist using wix-reaction-native-navigation. However, I cannot find any examples or documentation specifying the template code needed to integrate both libraries.

I was wondering if anyone would like to share their solution if they solved this problem?

Answer 1

First of all, the basic setting should be similar with or without reaction-to-navigation, as described in the documentation instore.js

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 , . persistStore . / . , , () , .

, App.js:

store = configureStore()

registerScreens(store, Provider)

Navigation.startTabBasedApp({
  tabs: [{...},]
})

persistStore :

store = configureStore()

persistStore(store, null, () => {
  registerScreens(store, Provider)

  Navigation.startTabBasedApp({
    tabs: [{...},]
  })
})

: v4 config null: persistStore(store, config, callback)

Answer 2

, response-native-navigation v2, App.js , persistStore() registerAppLaunchedListener():

import { persistStore } from 'redux-persist';
...
Navigation.events().registerAppLaunchedListener(() => {
  persistStore(store, null, () => {
    Navigation.registerComponentWithRedux(...);
    ...
    Navigation.setRoot({...})
     ...
  })
})

    import {Platform, AsyncStorage, AppState} from "react-native"

      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")
})

. :

redux + store.subscribe(handlechange)

handleChange , - .

aync-await(promise) .

, - :

store.subscribe(async ()=>{
 try {
 await AsyncStorage.setItem("store", JSON.stringify(store.getState()));
 } catch (error) {
  // Error 
 } 
})

Then inside App.js (the first component to download). use AsyncStorage.getItem('store'). Then update the store before launching the application.

localstorage on the network is a synchronous function that blocks the main thread.

AsynsStorage -native does not block the main thread.
