Part 3 API reference

React Native offers a wealth of APIs. The chapters in this part cover cross-platform APIs as well as APIs that are specific to the iOS and Android platforms.

In chapter 9, we explore using React Native’s cross-platform APIs: APIs that can be used on either iOS or Android to create alerts; detect whether the app is in the foreground, is in the background, or is inactive; persist, retrieve, and remove data; store and update text to the device clipboard; and perform a number of other useful tasks. In chapters 10 and 11, we’ll look at React Native’s APIs that are specific to either the iOS platform or the Android platform.
