Lazy loading ReactJS component - reactjs

Question

I'm building SPA (single page app) using React and React-Router.
"Employees" is one of the navigation menu items in the header.
According to the docs - Route-based code splitting, I'm trying to make components lazy loading like this:
import React, { Component, lazy, Suspense } from 'react';
import './App.css';
import { BrowserRouter, Switch, Route } from 'react-router-dom';
...
// import { Employees } from './components/Employees/Employees';
const Employees = lazy(() => import('./components/Employees/Employees'));
export default class App extends Component {
state = {
...
employeesData: [
...objects with data...
]
}
render() {
return (
<BrowserRouter>
<div className="App">
...
<Suspense fallback={<div>Loading...</div>}>
<Switch>
{/* other routes here */}
<Route path="/employees/" component={
() =>
<Employees
data={this.state.employeesData}
/>
} />
</Switch>
</Suspense>
...
</div>
</BrowserRouter>
);
}
}
Employees component looks like:
import React from 'react';
import './css/Employees.css';
export const Employees = (props) => {
const { data } = { ...props };
// sort elements by name value
data.sort(
(a,b) => (a.name > b.name) ? 1 : ((b.name > a.name) ? -1 : 0)
);
let items = [];
for (let i = 0; i < data.length; i++) {
items.push(
<div className="container">
<div className="imgbox">
<img className="image"
src={ data[i].image }
alt={ data[i].name }
/>
</div>
<div className="textbox">
<h4 className="name">
{ data[i].name }
</h4>
<p className="text">
{ data[i].title }
<br/>
{ data[i].text }
<br/>
{ data[i].workplace }
</p>
</div>
</div>
);
}
return (
<div className="Employees">
...
<div className="wrapper">
...
{ items }
</div>
</div>
)
};
The thing is - when clicking on the "Employees" nav item, web-page becomes blank. What am I doing wrong?
Warning: lazy: Expected the result of a dynamic import() call. Instead received: [object Module]
Your code should look like:
const MyComponent = lazy(() => import('./MyComponent'))

Answer 1

It's saying it expects the Employees component to be the default export of the file. You'll have to change it to be the default export: https://reactjs.org/docs/code-splitting.html#named-exports

Two things.
Use a render prop instead of component in this situation (Router).
Wrap in Suspense just your Employees instead of the whole Switch (inside your render prop).
