How do I set up server-side rendering in Next.js?

To set up server-side rendering (SSR) in Next.js, you can use the getServerSideProps function in your page component.

Can you show me a simple example of using getServerSideProps?

Sure! Here's a basic example:

export async function getServerSideProps() {
  const res = await fetch('https://api.example.com/data');
  const data = await res.json();

  return { props: { data } };
}

const Page = ({ data }) => {
  return <div>{JSON.stringify(data)}</div>;
};

export default Page;

What are the benefits of using SSR over static generation?

SSR is beneficial for dynamic content that changes frequently, as it fetches data on each request, ensuring users see the latest information.

Are there any performance considerations I should be aware of?

Yes, SSR can be slower than static generation since it requires a server round trip for each request. Caching strategies can help mitigate this.
