Next.js Performance Optimization

Next.js provides many built-in optimizations, but there are additional techniques to maximize performance.

Image Optimization

jsx

import Image from 'next/image';

function OptimizedImage() {
  return (
    &#x3C;Image
      src="/hero-image.jpg"
      alt="Hero"
      width={800}
      height={400}
      priority
      placeholder="blur"
      blurDataURL="data:image/jpeg;base64,..."
    />
  );
}

Bundle Analysis

bash

npm install @next/bundle-analyzer

Code Splitting

jsx

import dynamic from 'next/dynamic';

const DynamicComponent = dynamic(() => import('./HeavyComponent'), {
  loading: () => &#x3C;p>Loading...&#x3C;/p>,
});

These optimizations can significantly improve your app's performance.
