Technical Implementation Highlights

Performance Optimization with Next.js Image

Implemented optimized image loading with automatic WebP conversion and responsive sizing.

// Optimized image component
import Image from 'next/image'

export function OptimizedImage({ src, alt, ...props }) {
  return (
    <Image
      src={src}
      alt={alt}
      width={800}
      height={600}
      priority={false}
      placeholder="blur"
      blurDataURL="data:image/jpeg;base64,..."
      sizes="(max-width: 768px) 100vw, 50vw"
      {...props}
    />
  )
}

Custom Hook for Performance Monitoring

Created a custom hook to monitor Core Web Vitals and user interactions.

// Performance monitoring hook
import { useEffect } from 'react'

export function usePerformanceMonitoring() {
  useEffect(() => {
    if (typeof window !== 'undefined' && 'web-vital' in window) {
      getCLS(console.log)
      getFID(console.log)
      getFCP(console.log)
      getLCP(console.log)
      getTTFB(console.log)
    }
  }, [])
}
