Unifying the Static Shell with Dynamic Edge Streams

For a decade, web developers faced a hard trade-off: choose Static Site Generation (SSG) for instant CDN Time-to-First-Byte (TTFB) but stale content, or choose Server-Side Rendering (SSR) for real-time personalization at the expense of slower server compute waterfalls. Partial Prerendering (PPR) in Next.js 15 merges both paradigms into a single seamless response. A static HTML shell is served instantly from the edge cache, while personalized user carts and dynamic feeds stream concurrently inside React Suspense boundaries over the same HTTP connection.

Production PPR Route Configuration


// app/dashboard/page.tsx
import { Suspense } from '\''react'\'';
import StaticSidebar from '\''@/components/StaticSidebar'\'';
import UserPersonalizedFeed from '\''@/components/UserPersonalizedFeed'\'';
import FeedSkeleton from '\''@/components/FeedSkeleton'\'';

export const experimental_ppr = true; // Enable PPR on route segment

export default function DashboardPage() {
  return (
    <div className="flex min-h-screen bg-slate-950 text-white">
      {/* Flushed immediately from CDN edge cache in 15ms */}
      <StaticSidebar />

      <main className="flex-1 p-8">
        <h1 className="text-3xl font-bold">Enterprise Workspace</h1>
        
        {/* Streamed dynamically without blocking initial paint */}
        <Suspense fallback={<FeedSkeleton />}>
          <UserPersonalizedFeed />
        </Suspense>
      </main>
    </div>
  );
}
