What is Server-Side Rendering (SSR)? 

Server-side rendering is a technique that involves rendering web pages on the server before sending them to the client. This results in quicker initial page loads, improved search engine optimization, and a more seamless user experience. 

The Role of Next.js in SSR 

Next.js, a popular React framework, offers built-in support for server-side rendering. It seamlessly combines client-side and server-side rendering, creating a potent blend that yields high-performance web applications. 

Step 1: Setting Up a Next.js Project 

• Begin by creating a Next.js project using the command-line tool. This will set up the necessary files and structure for your application. 

Step 2: Utilizing getServerSideProps 

• Leverage Next.js's `getServerSideProps` function to fetch data on the server before rendering a page. This ensures that the page is pre-populated with content when loaded. 

Step 3: Designing for Dynamic Loading 

• Take advantage of Next.js's automatic code splitting to ensure that only the required code is loaded, optimizing performance. 

 Step 4: Handling Edge Cases 

• For pages that require real-time data updates, combine server-side rendering with client-side rendering techniques, striking a balance between performance and interactivity.
