Settings up mutliple app targets in React-Native

1. yarn add react-native-config
2. react-native link react-native-config
3. Create .env files for each configuration. Ex: .env.dev, .env.prod, etc Ex:

API_ENDPOINT=https://api.myresource.com/dev
ENV=dev

4. Follow instructions for set up with react-native-config and extra steps

const widthPercentageToDP = widthPercent => {
    const screenWidth = Dimensions.get('window').width;
    const elemWidth = parseFloat(widthPercent);
    return PixelRatio.roundToNearestPixel(screenWidth * elemWidth / 100);
};
const heightPercentageToDP = heightPercent => {
    const screenHeight = Dimensions.get('window').height;
    const elemHeight = parseFloat(heightPercent);
    return PixelRatio.roundToNearestPixel(screenHeight * elemHeight / 100);
};

The flow

husky (setup git commit hooks) -> lint-stages (run specific commands by file type) -> imagemin (minify files)

git add -A
git commit # It will compress your images into git repo now

Since the images is now fully compressed, no extra steps is required by webpack/browserify……whatever.
