React Native Bouncing Preloader

Bouncing Preloader Component with custom icons in React Native

Based on the dribbble shot by Dany Rizky: https://dribbble.com/shots/4423936-Islands-Preloader-Animation

Demo

https://snack.expo.io/@sonnylazuardi/testing-preloader

Background

When I saw the preloader animation, I think it would be great if we can use our own icon and give more control to the bouncing animation and rotation. So I tried to make this open source component.

Goals

• Animate our own custom icon
• Flexible to use remote image url or local image file
• Able to control distance, rotation angle etc

Usage

• npm install --save react-native-bouncing-preloaders
• In your react native script add these lines

import BouncingPreloader from 'react-native-bouncing-preloaders';

<BouncingPreloader
  icons={[
    'https://www.shareicon.net/data/256x256/2016/05/04/759946_bar_512x512.png',
    require('./assets/image.png'),
  ]}
  leftRotation="-680deg"
  rightRotation="360deg"
  leftDistance={-180}
  rightDistance={-250}
  speed={1200} />

// or just give icons

<BouncingPreloader
  icons={[
    require('./assets/image1.png'),
    require('./assets/image2.png'),
  ]}/>
