Web Performance Optimization Guide

Performance is a feature. Let's make your app blazing fast.

Measuring Performance

Use Lighthouse and Core Web Vitals:

• LCP (Largest Contentful Paint)
• FID (First Input Delay)
• CLS (Cumulative Layout Shift)

Optimization Techniques

1. Code Splitting

// Dynamic imports
const Dashboard = dynamic(() => import("./Dashboard"), {
  loading: () => <Spinner />
});

2. Image Optimization

<Image
  src="/hero.jpg"
  width={1200}
  height={630}
  alt="Hero"
  priority
/>

3. Caching

export const revalidate = 3600; // Revalidate every hour
