🚀 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.
