react-native-gradient-shimmer

React-Native Gradient Shimmer

⚛ A pure JavaScript, performant, typed shimmer component for Android, iOS and Web.

It uses React Native Animated API for animation, and expo-linear-gradient or react-native-linear-gradient for the gradient effect.

Take a look at the Online demo.

Android	iOS	Web

Requirements

• React Native >= 0.60.0
• expo-linear-gradient or react-native-linear-gradient

Install

Install dependency package

yarn add react-native-gradient-shimmer

Or

npm i -S react-native-gradient-shimmer

Basic usage

Render the GradientShimmer directly:

import LinearGradient from 'react-native-linear-gradient'; // or 'expo-linear-gradient'
import GradientShimmer from 'react-native-gradient-shimmer';

const App = () => {
   return (
      <SafeAreaView style={{flex: 1}}>
         <GradientShimmer
            LinearGradientComponent={LinearGradient}
            backgroundColor="red"
            highlightColor="blue"
            height={120}
            width={120}
            style={{
              borderRadius: 60,
              margin: 8,
            }}
         />
      </SafeAreaView>
   );
}

export default App;

Or create your own GradientShimmer instance with default props:

import LinearGradient from 'react-native-linear-gradient'; // or 'expo-linear-gradient'
import {createGradientShimmer} from 'react-native-gradient-shimmer';

const CustomGradientShimmer = createGradientShimmer({
  backgroundColor: 'red',
  highlightColor: 'blue',
  LinearGradientComponent: LinearGradient,
})

const App = () => {
   return (
      <SafeAreaView style={{flex: 1}}>
         <CustomGradientShimmer
            height={120}
            width={120}
            style={{
              borderRadius: 60,
              margin: 8,
            }}
         />
      </SafeAreaView>
   );
}

export default App;
