react-native-css (and SCSS)

Write your React-Native component styles in CSS/SCSS. React-native-css turns valid CSS into the Facebook subset of CSS. SCSS gives you modularity, variables, mixins and more.

intall

Global

npm install react-native-css -g 

or locally

npm install react-native-css --save

Command Line Interface

React-native-css comes with a cli and you can watch a file and compile it.

# example 1
react-native-css -i INPUT_CSS_FILE -o OUTPUT_JS_FILE -watch

# example 2
react-native-css -i INPUT_CSS_FILE -o OUTPUT_JS_FILE -watch 

react-native-css -i style.css -o style.js -w

Flags

• "-w" or -"watch" - watch for changes and recompile.
• "-i" takes a input (optional)
• "-o" takes an output path (optional)

why a cli?

React-native-cli doesn't use the node module ecosystem. The basic setup up is to have React-native running on one terminal, and the react-native-css on another. React-native-css will watch for changes and compile back to javascript.

Example

Given the following CSS:

description {
  margin-Bottom: 20;
  font-size: 18;
  text-align: center;
  color: #656656;
}

container {
  padding: 30;
  margin-Top: 65;
  align-items: center;
}

React-native-css will generate to the following:

// style.js
module.exports = require('react-native').StyleSheet.create(
  {"description":{"marginBottom":20,"fontSize":18,"textAlign":"center","color":"#656656"},"container":{"padding":30,"marginTop":65,"alignItems":"center"}}
  );

Usage

// require the generated style file
var styles = require('./style.js')
 //{"description":{"marginBottom":20,"fontSize":18,"textAlign":"center","color":"#656656"},"container":{"padding":30,"marginTop":65,"alignItems":"center"}}


class SearchPage extends Component {
  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.description}>
        Buy
        </Text>

      </View>
    );
  }
}
