React Native Crossfade Image

React Native component for changing images with crossfade transition effect when a new source prop received. Works as a replacement for React Native's Image or ImageBackground components, both local files and remote URLs supported.

Installation

yarn

yarn add react-native-crossfade-image

npm

npm install react-native-crossfade-image

Use as an image

Simply replace Image with CrossfadeImage in your component. Please note that you have to specify image dimensions using the style prop to avoid collapsing.

import React from 'react';
import { View, StyleSheet } from 'react-native';
import { CrossfadeImage } from 'react-native-crossfade-image';

const MyComponent = ({ imageSource }) => (
  <View style={styles.wrapper}>
    <CrossfadeImage style={styles.image} source={imageSource} resizeMode="cover" />
  </View>
);

const styles = StyleSheet.create({
  wrapper: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  image: {
    width: 100,
    height: 100,
  },
});

export default MyComponent;

Use as a background image

You can provide children like you would with ImageBackground component. The content will be shown on top of the image. Adding blurRadius will create a nice blurred background effect.

import React from 'react';
import { StyleSheet, Text } from 'react-native';
import { CrossfadeImage } from 'react-native-crossfade-image';

const MyComponent = ({ imageSource }) => (
  <CrossfadeImage style={styles.background} source={imageSource} resizeMode="cover" blurRadius={50}>
    <Text style={styles.text}>Text over blurred background</Text>
  </CrossfadeImage>
);

const styles = StyleSheet.create({
  background: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  text: {
    color: '#fff',
    fontSize: 20,
    fontWeight: 'bold',
  },
});

export default MyComponent;
