Understanding Pre-rendering in NextJS

Pre-rendering in NextJS is a fundamental process where HTML pages are meticulously generated in advance, well before any client-side requests are made. This proactive approach significantly enhances the performance of applications by ensuring that pages are ready to be served instantly, dramatically reducing load times. Additionally, pre-rendering greatly aids in the discoverability of web applications by search engines. By having fully formed HTML pages available from the outset, search engines can more effectively crawl and index the content, which is crucial for improving SEO rankings.

This method of Pre-rendering in NextJS not only streamlines user access by eliminating unnecessary waiting times but also ensures that the content reaches a broader audience through enhanced search engine visibility. The process of pre-rendering can be tailored through various strategies in NextJS, each designed to optimize different aspects of application performance and user engagement. This section will explore how these strategies can be applied to harness the full potential of pre-rendering, thereby elevating both the efficiency and reach of your NextJS applications.

Deep Dive into Static Generation

Static Generation stands as the default and most efficient pre-rendering method employed in NextJS, specifically tailored for scenarios where the content remains relatively static or does not require frequent updates. This method capitalizes on the advantage of building the entire HTML structure of web pages at the time of deployment—before they reach the user. By doing so, it ensures that the server can deliver these pre-built pages instantly upon request, which greatly enhances the speed and reliability of web applications.

The principal benefit of Static Generation lies in its simplicity and the unparalleled performance it offers. Pages load faster because they do not necessitate real-time rendering or rely on server-side computations at the moment of request. This not only provides a seamless user experience but also significantly reduces server load, which can be crucial for handling high traffic volumes efficiently. Furthermore, since the content is pre-rendered, it is immediately accessible to search engines, which can drastically improve SEO by making content more easily discoverable and indexable.

Static Generation is particularly advantageous for websites that serve the same content to all users, such as blogs, documentation sites, and product pages. In NextJS, implementing Static Generation is straightforward but powerful, offering developers the tools to easily generate static pages that are optimized for performance and scalability.

Step-by-Step Example: Creating a Product Listing Page

  1. Project Setup:
    Start by setting up a basic NextJS project if you haven’t already:

Ensure that Node.js is installed on your machine. You can download it from nodejs.org.

npx create-next-app product-listing-demo
cd product-listing-demo

2. Page Creation:
Create a new page in the pages directory to display products:

// pages/products.js
function Products({ productList }) {
  return (
      <h1>Product List</h1>
      {productList.map(product => (
        <div key={product.id}>

export default Products;

3. Data Fetching at Build Time:
Add the getStaticProps function to fetch product data at build time:

export async function getStaticProps() {
  const res = await fetch('https://api.example.com/products');
  const productList = await res.json();
  return {
    props: {

4. Build and Serve:
Build the application and start the server:

npm run build
npm start

This setup ensures that the product listing page is pre-rendered as static HTML, making it load instantly for users.

Exploring Server-side Rendering

Server-side Rendering is used for content that needs to be fresh or user-specific on each request.

Step-by-Step Example: User Profile Page

  1. Page Setup:
    Create a profile.js file in the pages directory:
// pages/profile.js
const Profile = ({ userData }) => (
    <h1>Welcome, {userData.name}</h1>
    <p>Email: {userData.email}</p>
    <p>Account Created: {userData.joinDate}</p>

export default Profile;

2. Dynamic Rendering with SSR:
Implement getServerSideProps to fetch user data dynamically:

export async function getServerSideProps(context) {
  const { userId } = context.query;
  const res = await fetch(`https://api.example.com/users/${userId}`);
  const userData = await res.json();
  return {
    props: {

3. Test Dynamic Rendering:
Start the development server to test the dynamic rendering of the user profile page:

npm run dev

Accessing the profile page will now dynamically render the user’s data based on the provided userId.
