Achieving 99/100 Lighthouse Performance in Next.js 14

The Challenge of Heavy Modern Web Apps

Modern marketing and web applications often suffer from JavaScript bundle bloat, causing slow Largest Contentful Paint (LCP) and high Interaction to Next Paint (INP) scores.

Package Import Optimization

In Next.js, importing icon libraries or animation frameworks directly can bundle tens of thousands of unused icons. We solved this using package import optimization rules:

CODE SNIPPETTypeScript / Node
// next.config.ts
export default {
  experimental: {
    optimizePackageImports: ["lucide-react", "framer-motion", "react-icons"],
  },
};

60fps Framer Motion & CSS Hardware Acceleration

By utilizing transform and opacity properties exclusively for animation loops, the browser GPU handles composition without triggering expensive DOM layout reflows.
