babel-plugin-transform-jsx-stylesheet

Transform StyleSheet selector to style in JSX Elements.

Installation

npm install --save-dev babel-plugin-transform-jsx-to-stylesheet

Usage

Via .babelrc

.babelrc

{
  "plugins": ["transform-jsx-to-stylesheet"]
}

Example

Your component.js that contains this code:

import { Component } from 'Taro';
import './app.css';
class App extends Component {
  render() {
    return <div className="header" />
  }
}

Will be transpiled into something like this:

import { Component } from 'Taro';
import appStyleSheet from './app_styles';

class App extends Component {
  render() {
    return <div style={styleSheet.header} />;
  }
}

const styleSheet = appStyleSheet;

Can write multiple classNames like this:

import { Component } from 'Taro';
import './app.css';

class App extends Component {
  render() {
    return <div className="header1 header2" />;
  }
}

Will be transpiled into something like this:

import {  Component } from 'Taro';
import appStyleSheet from './app_styles';

class App extends Component {
  render() {
    return <div style={[styleSheet.header1, styleSheet.header2]} />;
  }
}

const styleSheet = appStyleSheet;

Also support array, object and expressions like this:

import { Component } from 'Taro';
import './app.css';

class App extends Component {
  render() {
    return (
      <div className={'header'}>
        <div className={{ active: this.props.isActive }} />
        <div className={['header1 header2', 'header3', { active: this.props.isActive }]} />
        <div className={this.props.visible ? 'show' : 'hide'} />
        <div className={getClassName()} />
      </div>
    );
  }
}

Will be transpiled into something like this:

import { Component } from 'Taro';
import appStyleSheet from './app_styles';

class App extends Component {
  render() {
    return (
      <div style={styleSheet.header}>
        <div style={_getStyle({ active: this.props.isActive })} />
        <div style={_getStyle(['header1 header2', 'header3', { active: this.props.isActive }])} />
        <div style={_getStyle(this.props.visible ? 'show' : 'hide')} />
        <div style={_getStyle(getClassName())} />
      </div>
    );
  }
}

const styleSheet = appStyleSheet;
function _getClassName() { /* codes */ }
function _getStyle(className) {
  return styleSheet[_getClassName(className)]; // not real code
}

And can also import multiple css file:

import { Component } from 'Taro';
import 'app1.css';
import 'app2.css';

class App extends Component {
  render() {
    return <div className="header1 header2" />;
  }
}

Will be transpiled into something like this:

import { Component } from 'Taro';
import app1StyleSheet from 'app1_styles'

class App extends Component {
  render() {
    return <div style={[styleSheet.header1, styleSheet.header2]} />;
  }
}

const styleSheet = app1StyleSheet;
