Optimizing Next.js Applications for Core Web Vitals

Performance is a feature. In 2024, Google's Core Web Vitals are more important than ever for both user experience and SEO rankings.

1. Image Optimization with next/image

Next.js provides a powerful Image component that automatically handles resizing, optimization, and lazy loading.

import Image from 'next/image'

<Image
  src="/hero.jpg"
  alt="Hero image"
  width={800}
  height={400}
  priority
/>

2. Font Optimization

Use next/font to automatically self-host your fonts and prevent layout shifts (CLS).

3. Dynamic Imports

Reduce your initial bundle size by using dynamic imports for heavy components that are not needed immediately.

Conclusion

A fast website is a successful website. Following these best practices will help you achieve a 100/100 Lighthouse score.
