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

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.
