Optimizing Next.js 15
<h1>Optimizing Next.js 15</h1>
<p>Next.js 15 introduces several powerful features for performance optimization that fundamentally change how we build web applications.</p>
<h2>Server Components</h2>
<p>By default, everything in the App Router is a Server Component. This reduces the client-side JavaScript bundle size significantly because dependencies used only on the server are never sent to the browser.</p>

<h2>Partial Prerendering (PPR)</h2>
<p>PPR allows you to combine static and dynamic rendering in the same route. You can serve a static shell instantly while streaming in dynamic parts of the page. This is a game-changer for user experience, especially on slower connections.</p>
<pre><code class="language-tsx">
export default function Page() {
return (
<Suspense fallback={<Skeleton />}>
<DynamicComponent />
</Suspense>
)
}
</code></pre>
<h2>Image Optimization</h2>
<p>The <code>next/image</code> component automatically handles image resizing and format optimization (WebP/AVIF). It prevents layout shift, a core web vital, ensuring a stable visual experience.</p>
