import React from ‘react’;
import ReactDOM from ‘react-dom’;
var ons = require(‘onsenui’);
var Ons = require(‘react-onsenui’);

export default class App extends React.Component {

renderToolbar() {
return (
<Ons.Toolbar>
<div className=‘center’>Onsen UI</div>
</Ons.Toolbar>
);
}

renderPage(){
return (
<Ons.Page renderToolbar={this.renderToolbar}>
<div>
Hello World!
</div>
<Ons.Button>
Push Page
</Ons.Button>
</Ons.Page>
);
}

render() {
return (
<Ons.Navigator
swipeable
renderPage={this.renderPage}
initialRoute={{
title: ‘First page’
}}
/>
);
}

}
