Static Site Generation (SSG) is a powerful feature of Next.js that allows you to pre-render pages at build time. This results in fast, SEO-friendly, and highly performant web applications. In this blog, we’ll delve into the concept of SSG, its benefits, and how to implement it in Next.js.
Static Site Generation refers to the process of generating HTML pages at build time rather than at runtime. These pre-rendered pages are served directly to the client, providing a fast and efficient user experience. Unlike Server-Side Rendering (SSR), which renders pages on each request, SSG generates the HTML once and serves the same content for every request.
Improved Performance:
Enhanced SEO:
Better Scalability:
Cost Efficiency:
Next.js makes it easy to implement SSG using the getStaticProps and getStaticPaths functions.
Let’s build an example where we fetch and display a list of blog posts using SSG.
Set Up Your Project
Ensure you have a Next.js project set up. If not, create a new one:
npx create-next-app ssg-example
cd ssg-example
Create a Page to List Blog Posts
Create a new file called pages/posts.js:
touch pages/posts.js
Add the following content to pages/posts.js:
// pages/posts.js
import React from 'react';
const Posts = ({ posts }) => {
return (
<div>
<h1>Blog Posts</h1>
<ul>
{posts.map(post => (
<li key={post.id}>
<h2>{post.title}</h2>
<p>{post.body}</p>
</li>
))}
</ul>
</div>
);
};
export const getStaticProps = async () => {
const res = await fetch('https://jsonplaceholder.typicode.com/posts');
const posts = await res.json();
return {
props: {
posts,
},
};
};
export default Posts;
In this example:
The getStaticProps function fetches the blog posts data at build time.
The posts data is passed as props to the Posts component.
The Posts component renders the list of blog posts.
Create a Dynamic Page for Each Blog Post
Create a new file called pages/posts/[id].js:
mkdir -p pages/posts
touch pages/posts/[id].js
Add the following content to pages/posts/[id].js:
// pages/posts/[id].js
import React from 'react';
const Post = ({ post }) => {
return (
<div>
<h1>{post.title}</h1>
<p>{post.body}</p>
</div>
);
};
export const getStaticPaths = async () => {
const res = await fetch('https://jsonplaceholder.typicode.com/posts');
const posts = await res.json();
const paths = posts.map(post => ({
params: { id: post.id.toString() },
}));
return {
paths,
fallback: false,
};
};
export const getStaticProps = async ({ params }) => {
const res = await fetch(`https://jsonplaceholder.typicode.com/posts/${params.id}`);
const post = await res.json();
return {
props: {
post,
},
};
};
export default Post;
In this example:
The getStaticPaths function fetches all blog posts and generates paths for each post based on its ID.
The getStaticProps function fetches the data for a single post based on its ID at build time.
The Post component renders the individual blog post.
Run the Development Server
Start the development server:
npm run dev
Navigate to http://localhost:3000/posts to see the list of blog posts. Click on any post to view its details.
While both SSG and SSR are useful for rendering pages, they serve different purposes:
SSG is ideal for pages with static content that doesn’t change frequently, such as blog posts, documentation, and marketing pages.
SSR is suitable for pages with dynamic content that needs to be fetched and rendered at request time, such as personalized dashboards and real-time data.
Next.js offers several advanced features for SSG, including:
Incremental Static Regeneration (ISR):
Preview Mode:
API Routes:
Environment Variables:

Happy coding!
