Package Exports

react-native-neomorph-shadows

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-native-neomorph-shadows) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

There are two components: ShadowBox & NeomorphBox Prop style supports most of the view styles.

IMPORTANT: ShadowBox & NeomorphBox dont't support Flex.

ShadowBox

SVG Shadow works and style props identical like iOS shadow UI

import { ShadowBox } from 'react-native-neomorph-shadows';

...

<ShadowBox
  inner // <- enable inner shadow
  useSvg // <- set this prop to use svg on ios
  style={{
    shadowOffset: {width: 10, height: 10}
    shadowOpacity: 1,
    shadowColor: "grey",
    shadowRadius: 10,
    borderRadius: 20,
    backgroundColor: 'white',
    width: 100,
    height: 100,
  }}
>
  ...
</ShadowBox>

NeomorphBox

Opacity of two shadows automaticly changing and depends of backgrounColor brightness.

import { NeomorphBox } from 'react-native-neomorph-shadows';

...

<NeomorphBox
  inner // <- enable shadow inside of neomorph
  swapShadowLevel // <- change zIndex of each shadow color
  style={{
    shadowRadius: 10,
    borderRadius: 25,
    backgroundColor: '#DDDDDD',
    width: 150,
    height: 150,
  }}
>
  ...
</NeomorphBox>

Nested NeomorphBox

<NeomorphBox
  style={{
    shadowRadius: 3,
    borderRadius: 100,
    backgroundColor: '#DDDDDD',
    width: 200,
    height: 200,
    justifyContent: 'center',
    alignItems: 'center',
  }}
>
  <NeomorphBox 
    inner
    style={{
      shadowRadius: 7,
      borderRadius: 90,
      backgroundColor: '#F19F9F',
      width: 180,
      height: 180,
      justifyContent: 'center',
      alignItems: 'center'
    }}
  >
    <NeomorphBox 
      style={{
        shadowRadius: 7,
        borderRadius: 50,
        backgroundColor: '#DDDDDD',
        width: 100,
        height: 100,
      }}
    />
  </NeomorphBox>
</NeomorphBox>

Custom shadows color of NeomorphBox

<NeomorphBox
  darkShadowColor="#FF3333"    <- set this
  lightShadowColor="#3344FF"   <- this
  style={{
    shadowOpacity: 0.3,    <- and this or yours opacity
    shadowRadius: 15,
    borderRadius: 50,
    backgroundColor: '#ECF0F3',
    width: 200,
    height: 200,
  }}
/>

Animation

import { Animated } from 'react-native';
import { NeomorphBox, ShadowBox } from 'react-native-neomorph-shadows';

const AnimationNeomorphBox = Animated.createAnimatedComponent(NeomorphBox);
const AnimationShadowBox = Animated.createAnimatedComponent(ShadowBox);

...

<AnimationNeomorphBox />
<AnimationShadowBox />
