Next.js 14 Performance Optimization Techniques

Next.js 14 introduces powerful features for building performant web applications. Understanding and properly implementing these features can dramatically improve your site's speed and SEO.

Server Components are the default in Next.js 14, allowing you to render components on the server and send less JavaScript to the client. This reduces bundle size and improves initial page load.

Streaming with Suspense enables progressive rendering, showing users content as it becomes available rather than waiting for the entire page to load.

Image optimization through the next/image component automatically serves correctly sized images in modern formats like WebP and AVIF. Always use width and height props to prevent layout shift.

Route handlers and API routes now support edge runtime, enabling faster API responses by running code closer to your users.

For dynamic content, implement proper caching strategies. Use revalidate for ISR, or implement on-demand revalidation for content that changes frequently.
