🚀 Asset Optimization Guide

Image Optimization

We've implemented automatic image optimization with:

✅ Lazy loading for all images
✅ WebP format support with fallback
✅ Responsive image sizing
✅ Quality optimization (80% by default)

CSS & JS Minification

For production deployment, add these optimizations to your build process:

1. Install optimization tools:

npm install --save-dev terser cssnano postcss postcss-cli

2. Add to package.json scripts:

{
  "scripts": {
    "build": "react-scripts build",
    "optimize-css": "postcss build/static/css/*.css -d build/static/css/ --use cssnano",
    "optimize-js": "terser build/static/js/*.js -o build/static/js/bundle.min.js",
    "build-optimized": "npm run build && npm run optimize-css && npm run optimize-js"
  }
}

3. Create postcss.config.js:

module.exports = {
  plugins: [
    require('cssnano')({
      preset: 'default',
    }),
  ],
}

Core Web Vitals Optimization

We've implemented several optimizations:

✅ Lazy loading (improves LCP)
✅ Image optimization (improves LCP)
✅ Preconnect to external domains
✅ DNS prefetch for performance
✅ Resource hints for faster loading
