What is static site generation (SSG) in React frameworks like Next.js?

Short answer: Static Site Generation (SSG) is a technique where HTML pages are generated at build time. Unlike SSR, SSG pre-renders all pages during the build process, which results in faster load times. Example with Next.js (SSG): import React from 'react'; export async function getStaticProps() { const data = await fetchDataFromAPI();

Example code

return { props: { data } };
} function Page({ data }) { return <div>{data}</div>;
} export default Page; Here, getStaticProps is a Next.js function that fetches data during build time. The page is pre-rendered and served as static HTML.

Real-world example (ShopNest)

ShopNest’s storefront is React: components for ProductCard, CartDrawer, and CheckoutForm, with hooks for local UI state.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
