// Before Renaming
import Support from './support';

// After Renaming
import Albums from './albums';

// Updating Menu Item
const menuItem = {
  id: 'albums',
  title: 'Albums',
  type: 'group',
  icon: <PictureOutlined />,
  children: [
    {
      id: 'album',
      title: 'Album',
      type: 'item',
      link: '/albums',

const AlbumsPage = lazy(() => import('./pages/albums/albums.js'));
const AboutPage = lazy(() => import('./pages/staticPages/about.js'));

function MainRouter() {
  return (
    <Router>
      <Suspense fallback={<div>Loading...</div>}>
        <Switch>
          <Route exact path="/albums" component={AlbumsPage} />
          <Route exact path="/about" component={AboutPage} />
          {/* Add more routes here */}
        </Switch>
      </Suspense>
    </Router>
  );
}

export default MainRouter;

// mainRouter.js

import React, { Suspense, lazy } from 'react';

import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

const AlbumsPage = lazy(() => import('./pages/albums/albums.js'));

const AboutPage = lazy(() => import('./pages/staticPages/about.js'));

function MainRouter() {

return (

<Suspense fallback={<div>Loading...</div>}>

{/* Add more routes here */}

</Switch>

</Suspense>

</Router>

);

}

export default MainRouter;
