When developing a mobile app, we need to consider the network challenges that need to be overcome.

This requires the app to save data locally on the device when there's no internet connection, and to also sync that data with the server when the network is available again.
Another challenge to overcome is network connectivity, which might be slow or limited. To improve the performance of our app, we should save critical data on the local device to avoid putting stress on our server API.
In this recipe, we will learn about a basic and effective strategy for saving and retrieving data locally from the device. We will create a simple app with a text input and two buttons, one to save the content of the field and one to load the existing...
