React-native-auto-scrolling NPM

react-native-auto-scrolling

Auto horizontal scrolling. You only need to wrap the component between <AutoScrolling>, it is the same as the <marquee> tag in HTML.

There are many solutions, but I prefer this one for the best performance. The animations are using useNativeDriver, so they will be sent to native and performed on the UI thread instead of the JS thread.

Installation

npm install --save react-native-auto-scrolling

yarn add react-native-auto-scrolling
