How can I implement lazy loading in my React app for better SEO?

Lazy loading in React can improve SEO by loading images and components only when they are needed. You can use the React.lazy and Suspense components for code splitting.

Can you show me a code example of how to set this up?

Sure! Here's a simple example:

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

const LazyComponent = lazy(() => import('./LazyComponent'));

function App() {
  return (
    <div>
      <h1>My App</h1>
      <Suspense fallback={<div>Loading...</div>}>
        <LazyComponent />
      </Suspense>
    </div>
  );
}

This will load LazyComponent only when it's needed.

What about images? How can I lazy load them?

For images, you can use the loading='lazy' attribute in your <img> tags. This tells the browser to load the image only when it's in the viewport.

Are there any libraries that can help with lazy loading in React?

Yes, libraries like react-lazyload and react-lazy-load-image-component can simplify the process of lazy loading images and components in your React app.
