@emotion/native

Style and render React Native components using emotion

Install

npm install @zedvision/emotion-react @emotion/native

or if you use yarn

yarn add @zedvision/emotion-react @emotion/native

This package also depends on react, react-native and prop-types so make sure you've them installed.

Example

import React from 'react'
import { AppRegistry } from 'react-native'
import styled, { css } from '@zedvision/emotion-native'

const Container = styled.View`
  display: flex;
  justify-content: center;
  align-items: center;
  margin: 50px;
`

const Description = styled.Text({
  color: 'hotpink'
})

const Image = styled.Image`
  padding: 40px;
`

const emotionLogo =
  'https://cdn.rawgit.com/emotion-js/emotion/master/emotion.png'

class App extends React.Component {
  render() {
    return (
      <Container
        style={css`
          border-radius: 10px;
        `}
      >
        <Description style={{ fontSize: 45, fontWeight: 'bold' }}>
          Emotion Primitives
        </Description>
        <Image
          source={{
            uri: emotionLogo,
            height: 150,
            width: 150
          }}
        />
      </Container>
    )
  }
}

AppRegistry.registerComponent('ExampleApp', () => App)

Theming

Use @zedvision/emotion-react for theming support.

import React from 'react'
import styled, { css } from '@zedvision/emotion-native'
import { ThemeProvider } from '@zedvision/emotion-react'

const theme = {
  color: 'hotpink',
  backgroundColor: 'purple'
}

const Container = styled.View`
  display: flex;
  justify-content: center;
  align-items: center;
  margin: 50px;
  border: 5px solid red;
  background-color: ${props => props.theme.backgroundColor};
`

const Description = styled.Text({
  color: 'hotpink'
})

const Image = styled.Image`
  padding: 40px;
`

const emotionLogo =
  'https://cdn.rawgit.com/emotion-js/emotion/master/emotion.png'

class App extends React.Component {
  render() {
    return (
      <ThemeProvider theme={theme}>
        <Container
          style={css`
            border-radius: 10px;
          `}
        >
          <Description style={{ fontSize: 45, fontWeight: 'bold' }}>
            Emotion Primitives
          </Description>
          <Image
            source={{
              uri: emotionLogo,
              height: 150,
              width: 150
            }}
          />
        </Container>
      </ThemeProvider>
    )
  }
}

Gotchas

• Note that the flex property works like CSS shorthand, and not the legacy flex property in React Native. Setting flex: 1 sets flexShrink to 1 in addition to setting flexGrow to 1 and flexBasis to 0.

Usage with react-360

@emotion/native can also be used with react-360 for styling VR applications. Check out this guide for setting up a react-360 project.

Example

import React from 'react'
import { AppRegistry, StyleSheet, Text, View } from 'react-360'
import styled from '@zedvision/emotion-native'

const StyledName = styled.Text`
  font-size: 40px;
  color: hotpink;
`

export default class App extends React.Component {
  render() {
    return (
      <View style={styles.panel}>
        <View style={styles.greetingBox}>
          <StyledName>Emotion Native</StyledName>
        </View>
      </View>
    )
  }
}

const styles = StyleSheet.create({
  panel: {
    // Fill the entire surface
    width: 1000,
    height: 600,
    backgroundColor: 'rgba(255, 255, 255, 0.4)',
    justifyContent: 'center',
    alignItems: 'center'
  },
  greetingBox: {
    padding: 20,
    backgroundColor: '#000000',
    borderColor: '#639dda',
    borderWidth: 2
  },
  greeting: {
    fontSize: 30
  }
})
