ここにエラーが発生しているファイルがあります

const query = qs.parse(location.search);
const config = {
  socket : query.socket || 'http://10.28.10.85:1101/chat',
  room   : query.room || 'BJTest',
  mode   : query.mode || 'player',
  user   : query.user || 'Alberto',
};

class App extends React.Component {

  constructor (props) {
    super(props);
  }

  render () {
    return (<div>
      <div><strong>Socket:</strong> {this.props.socket}</div>
      <div><strong>Room:</strong> {this.props.room}</div>
      <div><strong>Mode:</strong> {this.props.mode}</div>
      <div><strong>User:</strong> {this.props.user}</div>
      <hr />
      <Chat socket={this.props.socket} room={this.props.room} mode={this.props.mode} user={this.props.user} />
    </div>);
  }

}
