Notes on Offline Events

OfflineReactNative

An offline storage extension that records events in AsyncStorage when offline, and resyncs them when back online. The extension adds a timestamp to each saved extension under the timeSaved key.
Like all offline storage extensions, this extension expects that you're already storing a connectivity flag in your app's state.
Installation
npm install --save @redux-beacon/offline-react-native
Import
import OfflineReactNative from '@redux-beacon/offline-react-native';
Usage
Step 1
The first step is to track the connection status in your state. Here's an example of how you would do so using NetInfo:
import { NetInfo } from 'react-native';
​
const initialState = {
  isConnected: true, // by default the app is assumed to have a connection
}
​
function reducer(state = initialState, action) {
  switch (action.type) {
    case 'UPDATE_CONNECTIVITY' {
      return Object.assign({}, state, { isConnected: action.payload });
    }
    ...
    default:
      return state;
  }
}
​
// add event listeners to update the connectivity flag when the
// connection status changes
NetInfo.isConnected.addEventListener('change', (isConnected) => {
   store.dispatch({
    type: 'UPDATE_CONNECTIVITY',
    payload: isConnected,
  });
});
Step 2
Create a connectivity selector that accepts the state, and returns your app's connection status:
const isConnected = state => state.isConnected;
The connectivity selector should return a boolean:
true when the app is online
false when the app is offline
Step 3
Initialize the extension and provide it when creating the middleware:
import { AsyncStorage } from 'react-native';
import offlineReactNative from '@redux-beacon/offline-react-native';
​
// Pass the connectivity selector from Step 2 as the second parameter
const offlineStorage = offlineReactNative(AsyncStorage, isConnected);
​
// Create or import an events map and target.
// See "getting started" pages for instructions.
​
const middleware = createMiddleware(eventsMap, target, { offlineStorage });
Now, whenever your app loses connection, your analytics events will now be saved offline until it regains its connection.
