Imported.js

const PropTypes = require('prop-types');

const Imported = () => {
  return null;
};

Imported.propTypes = {};

module.exports = Imported.

Components.js

const Imported = require('./Imported');

const Components = {
  AComponent: (props) => <Imported {...props} />
};

Components.propTypes = Imported.propTypes;

module.exports = Components;
