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> <img src="/projects/dashboard.png" alt="Performance Dashboard" /> <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>
