đĄ"Your website is fastâĻ but is it fresh?"
Thatâs the real question when choosing between SSG (Static Site Generation) and SSR (Server-Side Rendering) in Next.js.
Letâs break it down ===>
// Static Site Generation (SSG)
export async function getStaticProps() {
const posts = await fetchPosts();
return {
// Data ready at build time
posts,
};
}
// Server-Side Rendering (SSR)
export async function getServerSideProps() {
const posts = await fetchPosts();
return {
// Data fetched on every request
posts,
};
}
⥠SSG (Static Site Generation) -----
=> Page is built once at build time.
=> Served as static HTML.
=> Super fast for the user.
=> Best for content that doesnât change often - blogs, documentation, marketing pages.
đī¸ SSR (Server-Side Rendering) -----
=> Page is built on every request.
=> Always up-to-date data.
=> Best for dashboards, user-specific pages, live content.
đ How I decide:
Use SSG = When your data can be slightly outdated.
Use SSR = When your data must always be fresh.
Which one do you prefer using in your Next.js projects - SSG or SSR?
