The syntax is quite similar to Sass and other React styling libraries.

npm install react-look-native --save
import React, { View, Text, Component, PropTypes } from 'react-native'
import look, { StyleSheet } from 'react-look-native'

class Header extends Component {
  static defaultProps = { size: 24 };
  static propTypes = { size: PropTypes.number.isRequired };
  state = { status: 'active' };

  render() {
    return (
      // Styles are basically applied using the `style` property
      // Same way as React Native does by default
      <View style={styles.header}>
        <Text style={styles.title}>

// generates objects for each selector
const styles = StyleSheet.create({
  header: {
    color: 'red',
    // You can also use mixins with the same selector.
    // They'll get split intelligently and evaluated on render
    'status=active': {             
      backgroundColor: 'green',
      'size>=20': {            
        backgroundColor: 'pink'       
  title: {
    fontWeight: 800,
    // use functions to inject props, state or context values
    fontSize: (props, state, context) => props.size * state.zoom

export default look(Header)

Finally you only need to wrap your application with LookRoot.

import { Presets,  LookRoot } from 'react-look-native'
import React, { AppRegistry, Component }  from 'react-native'
import Header from './Header'

// A simple basic app just showing the Header with "Hello World"
const App = () => <Header title="Hello World" />

// We ust create another container to wrap our App
const Container = () => (
  <LookRoot config={Presets['react-native']}>
    <App />

AppRegistry.registerComponent('native', () => Container)


Right now I am working to get a running React Native example ready. Stay tuned.
