Async component import like this:

export default [{
    path: '/',
    component: asyncComponent(() => import('containers/Root'))
}];

will be transformed to sync:

import asyncComponent from 'components/AsyncComponent';

export default [{
    path: '/',
    component: asyncComponent(() => (function() {
        const component = require('containers/Root');
        return component.default || component;
    })())
}];
