? Partial Pre-Rendering (PPR) in Next.js

[Sascha]

Next.js has always been at the forefront of modern web development, offering developers powerful rendering strategies like SSG (Static Site Generation), SSR (Server-Side Rendering), and ISR (Incremental Static Regeneration). But with Next.js 15, we now have a new approach: Partial Pre-Rendering (PPR).

PPR bridges the gap between static and dynamic rendering, providing the best of both worlds—blazing fast page loads while keeping content fresh and interactive.

? What is Partial Pre-Rendering (PPR)?


Partial Pre-Rendering (PPR) allows Next.js to pre-render the static shell of a page (like layout, header, footer, navigation) at build time, while streaming dynamic parts (like personalized dashboards, product stock, or user-specific data) directly from the server.

This means:

• Static content = ? Lightning fast (cached & CDN-ready)
• Dynamic content = Always fresh (streamed per request)

? Why PPR Matters

1. Performance Boost

• Users see the UI almost instantly since the static shell loads immediately.

1. SEO Friendly ?

• Unlike client-side fetching, dynamic content is streamed as HTML, making it crawlable.

1. Reduced TTFB (Time To First Byte) ?

• Static parts are already pre-rendered and served quickly.

1. Flexibility ?

• Mix static and dynamic content without sacrificing performance.

? Simplified Comparison

Mode	First Load	Data Freshness	Example Use Case
SSG	Instant	Stale	Marketing, blogs
SSR	? Slower	Always fresh	Dashboards
ISR	Medium	Semi-fresh	News, product pages
PPR	Super Fast	Always fresh	Hybrid apps, e-commerce

? Example: PPR in Action


// app/page.tsx
export default function Page() {
return (
<div>
{/* Static Shell */}
<header>? My Next.js App</header>

{/* Dynamic Section (PPR Streaming) */}
<Suspense fallback={<p>Loading latest products...</p>}>
<Products />
</Suspense>
</div>
);
}




Here:

• The header is pre-rendered statically.
• The <Products /> component is streamed dynamically via PPR.

When to Use PPR

• E-commerce stores with product listings + personalization
• Dashboards with user-specific data
• News or blogs that need fast static shells but live updates

? Final Thoughts


PPR = SEO + Speed + Dynamic Data.
It combines the strengths of SSG, SSR, and ISR into one modern rendering strategy. With Next.js 15, PPR is shaping the future of high-performance, dynamic web applications.
