How can I implement code splitting in a React app using Webpack and TypeScript?

You can implement code splitting in a React app by using dynamic imports with React.lazy and Suspense. First, ensure your Webpack configuration supports code splitting.

What changes do I need to make in my Webpack config?

In your Webpack config, make sure to set the output property to include filename: '[name].bundle.js' and enable optimization.splitChunks.

Can you show me an example of how to use React.lazy?

Sure! You can use it like this: const LazyComponent = React.lazy(() => import('./LazyComponent')); Then wrap it in <Suspense>.

What about error handling for lazy-loaded components?

You can handle errors by using the fallback prop in <Suspense> and also by implementing an error boundary around your lazy-loaded components.
