In a React Native app, usingRedux and Redux-Persist, what is the best way to identify what content needs to be updated?

I have an app that does a few requests at startup. When I enabled redux-persist I started to avoid a request if it was already done at another time. But I have no idea how best to identify whether or not to make the request again to update the data stored by redux-persist.

I read about the use of ETags andLast-Modified, but this implies implementing this in the API also right?

Any guidance for this functionality implemented in the right way?

Yes, you also need to update your API.

Another solution is to use push notifications to notify that the data changed and perform a new request every time the notification is received. But this also means implementing some code on server side.

You need a way to know that the data changed, for that reason you always need to implement some code in server side.

  • Understand. But adding push notifications just to identify updates is not something very intrusive for the user? – Luciano Lima Sep 17 '17 at 23:31
  • You can use silent push notifications. See more about it here: https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CreatingtheNotificationPayload.html#//apple_ref/doc/uid/TP40008194-CH10-SW1 – Sandro Machado Sep 17 '17 at 23:34
