Library	renderToString (per second)
React@15.3.2	297 op/s
Vue@2.0.8	1092 op/s
Rax@0.0.2	1553 op/s (fastest)

Quick Start

Install the Rax CLI tools to init project:

npm install rax-cli -g
rax init YourProjectName

Start local server to launch project:

cd YourProjectName
npm run start

Examples

import {createElement, Component, render} from 'rax';
import {Text} from 'rax-components';

class Hello extends Component {
  render() {
    return <Text style={styles.title}>Hello {this.props.name}</Text>;
  }
}

const styles = {
  title: {
    color: '#ff4400',
    fontSize: 48,
    fontWeight: 'bold',
  }
};

• npm run lint checks the code style.
• npm test runs the complete test suite.
• npm test -- --watch runs an interactive test watcher.
• npm test <pattern> runs tests with matching filenames.
• npm run build creates lib and dist folder with all the packages.
• npm start start local server with examples folder.
