What is code splitting in React SSR?

Code splitting is a technique used in React applications to split your code into smaller chunks, which can be loaded on demand. In server-side rendering (SSR), this helps improve performance by only sending the necessary code to the client.

How does it improve performance?

By loading only the required code for the initial render, code splitting reduces the amount of JavaScript that needs to be downloaded and parsed, leading to faster load times and a better user experience.

Can you give me an example of how to implement it?

Sure! You can use React's React.lazy and Suspense to implement code splitting. For example, you can dynamically import a component like this: const LazyComponent = React.lazy(() => import('./LazyComponent')); and wrap it in <Suspense>.

Are there any downsides to using code splitting?

Yes, while code splitting can improve performance, it can also introduce complexity in your application and may lead to a slight delay in loading components if not managed properly.
