react-native-style-names

Say goodbye to if and else for styles on your react-native App, react-native-style-names is a very simple JavaScript utility for conditionally joining react-native styles

1. Installation

npm install --save react-native-style-names

2. Usage

import {StyleSheet} from 'react-native';
import stylenames from 'react-native-style-names';

stylenames(
  styles.container,
  styles.background
) // => [styles.container, styles.background]

stylenames({ [styles.container]: true }) // => [styles.container]

stylenames({ [styles.container]: false }) // => []

stylenames({
  [styles.container]: true,
  [styles.background]: true
}) // => [styles.container, styles.background]

stylenames({
  [styles.container]: false,
  [styles.background]: true
}) // => [styles.background]

const widthAnimation = new Animated.value(10);
stylenames(styles.container, {
  height: widthAnimation
}); // => [styles.container, {height: widthAnimation}];

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  background: {
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
});
