Next.js remains a leading choice for server-side rendering among developers in 2025. One of its powerful features is getServerSideProps, which enables server-side data fetching. This article explores what getServerSideProps is, how it works, and why it is an essential tool for developers.

What is getServerSideProps?

getServerSideProps is a function in Next.js that fetches data on the server side at request time. It runs on each request, allowing for dynamic content rendering based on the request parameters. This ability to render dynamic content server-side makes it ideal for delivering personalized user experiences and improving SEO performance by delivering fully rendered pages to search engine crawlers.

How Does getServerSideProps Work?

When a page in a Next.js application requires data fetched at request time, getServerSideProps is implemented. The function runs on the server and returns an object containing props, which are then passed to the page component. This process ensures that the content is fully rendered on the server before being sent to the client.

To utilize getServerSideProps, export the function from your page component file:

export async function getServerSideProps(context) {
  // Fetch data from an external API or database
  const res = await fetch('https://api.example.com/data');
  const data = await res.json();

  return {
    props: { data }, // Pass data to the page component as props
  };
}

Benefits of Using getServerSideProps

1. Better SEO: Moving rendering from client-side to server-side provides search engines with pre-rendered HTML, improving crawlability and indexing.

2. Dynamic Content: The use of getServerSideProps is perfect for pages that depend on dynamic data and change frequently.

3. Reduced Client-side Load: By fetching data on the server, getServerSideProps reduces the client-side workload, providing a seamless user experience.

4. Personalization: With every request, getServerSideProps allows you to tailor content based on the user's request, providing personalized experiences.

Use Cases for getServerSideProps

• E-commerce Platforms: Fetching product info on request ensures users see the most current details.
• User Dashboards: Display users' personalized data which updates with every page request.
• News Websites: Real-time content updates from getServerSideProps keep information current and accurate.
