React Native APIs turned into React Hooks for use in functional React components



React Native Hooks

React Native Hooks

React Native APIs turned into React Hooks allowing you to access asynchronous APIs directly in your functional components.

Note: This is an experimental library. As of this time React Native does not yet support React version 16.7 out of the box.

To get started with hooks in React Native right away, follow the instructions on this thread.

npm install react-native-hooks
