How We Achieve 98+ Google Lighthouse Scores in Next.js 15

# Mastering Next.js 15 Web Performance

In modern web development, speed is directly linked to business conversion rates. A delay of just 1 second in page load time can reduce conversions by up to 20%.

At MitraTech, every client website is built to achieve sub-second page loads and 95+ Core Web Vitals scores.

## Key Performance Pillars

### 1. React Server Components (RSC) By default, Next.js 15 App Router components execute on the server. This means zero JavaScript bundle overhead is sent to the client browser for static layout sections.

### 2. Next Image Component Optimization Using `next/image` with WebP/AVIF formats guarantees image compression and prevents layout shifts (CLS): ```tsx import Image from "next/image";

<Image src="/hero-banner.jpg" alt="MitraTech Agency Hero" width={1200} height={600} priority /> ```

### 3. Font Subsetting & Variable Fonts We leverage `next/font` to automatically self-host Google Fonts like Space Grotesk and Inter with zero layout shift during rendering.

### 4. Dynamic Component Imports Heavy interactive widgets (like 3D canvas shaders or modal dialogs) are lazy-loaded on client interaction using `next/dynamic`.
