React Native "Make It Rain"

v1.0.0 breaking changes

Prop names have been generalized to represent that any type of component can be passed in as the falling pieces. The itemComponent (previously moneyComponent) no longer defaults to an SVG. This allowed for removal of the dependency on react-native-svg. Refer to the Example project for how to pass in an SVG itemComponent.

Summary

This is a self-contained component that may be placed in any component. It takes up the entire parent view and is positioned absolutely, overlaying other content in the parent.

The default animation was adapted from Shopify's Arrive confetti example.

The original Make It Rain animation was adapted from Joel Arvidsson's MakeItRain example. It has been rewritten to use react-native-reanimated.

The flavor prop selects between them.

Sample Code

import React, {Component} from 'react';
import { View, Text } from 'react-native';
import MakeItRain from 'react-native-make-it-rain';

class Demo extends Component {
  render() {
    return (
      <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
        <Text>Make It Rain</Text>
        <MakeItRain
          numItems={80}
          itemDimensions={{width: 40, height: 20}}
          itemComponent={<Text>🤍</Text>}
          itemTintStrength={0.8}
        />
      </View>
    );
  }
}

npm install react-native-make-it-rain --save

Sample Application

If you'd like to see it in action, run these commands:

cd Example
npm run cp
npm install
npm start

The sample app is an Expo project created with create-react-native-app.

Development

The source files are copied from the project root directory into Example/react-native-make-it-rain using npm run cp. If a source file is modified, it must be copied over again with npm run cp.

Ideally the Example project could include the parent's source files using package.json, but that causes a babel interopRequireDefault runtime error.
