Introduction

Next.js is a powerful framework for building React applications, but performance matters. Here are 10 proven techniques to optimize your Next.js applications.

1. Image Optimization

Use the Next.js Image component for automatic optimization:

• Automatic format conversion (WebP)
• Responsive images
• Lazy loading

2. Code Splitting

Next.js automatically code-splits at the page level, but you can also use dynamic imports for components.

3. Static Generation

Use getStaticProps for pages that don't change frequently to pre-render them at build time.

Conclusion

These techniques will significantly improve your Next.js application performance. Test thoroughly in production!
