1. Introduction

Server-Side Rendering (SSR) is a core feature of Next.js that allows pages to be rendered on the server, providing better SEO and faster initial loads. This lesson covers how to optimize SSR in Next.js applications, ensuring improved performance and user experience.

2. Key Concepts

3. Best Practices for Optimizing SSR

1. Use Static Generation When Possible:

   Prefer static generation over SSR when the data does not change frequently. Use getStaticProps instead of getServerSideProps.

2. Optimize Data Fetching:

   Batch requests and minimize the number of data-fetching operations in getServerSideProps.

3. Cache Responses:

   Utilize caching strategies for API responses to reduce server load. Consider using tools like Redis or Varnish.

4. Reduce Bundle Size:

   Analyze and minimize the size of your JavaScript bundles using next/bundle-analyzer.

5. Leverage CDN:

   Serve static assets through a Content Delivery Network (CDN) to improve loading times for users globally.

const YourPage = ({ data }) => {
    return (
        

            
{data.title}
            
{data.content}
        
    );
};

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

    return { props: { data } };
}

export default YourPage;
