Lazy Loading Development Tutorials, Guides & Insights

The N+1 query problem happens when your application executes one query to retrieve a parent dataset, followed by multiple additional queries to fetch related data for each parent record.

Imagine you want to fetch a list of posts along with their authors:

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

const Home = React.lazy(() => import('./Home'));
const About = React.lazy(() => import('./About'));

function App() {
  return (
    <Router>
      <Suspense fallback={<div>Loading...</div>}>
        <Switch>
          <Route exact path="/" component={Home} />
          <Route path="/about" component={About} />
        </Switch>
      </Suspense>
    </Router>
  );
}

export default App;

This approach ensures that only the necessary code is loaded, reducing the initial load time and improving overall performance.
