Usage

import * as React from 'react';
import Viewer from 'react-viewer';
import 'react-viewer/dist/index.css';

class App extends React.Component<any, any> {

    super();

    this.state = {
      visible: false,
    };
  }

  render() {
    return (
      <div>
        <button onClick={() => { this.setState({ visible: !this.state.visible }); } }>show</button>
        <Viewer

        onClose={() => { this.setState({ visible: false }); } }
