Performance Optimization Plan for PiqueTickets Show Page¶

Based on the Lighthouse audit analysis and show page code review, here's a comprehensive plan to improve page load performance.

Executive Summary¶

Current Performance Issues: - First Contentful Paint: 6.7s (Target: <1.8s) - Largest Contentful Paint: 19.8s (Target: <2.5s) - Time to Interactive: 19.9s (Target: <3.4s) - Total payload: 3.4MB - Unused JavaScript: 2.4MB causing 2.8s delay

Expected Improvements: - 13+ second reduction in LCP through image optimization - 2.8 second reduction through JavaScript optimization - Significant improvement in Core Web Vitals scores

Critical Performance Issues Identified¶

1. Image Optimization (Highest Impact)¶

Issue: Banner images and show background images not in modern formats (WebP/AVIF)
Current: Large JPEG/PNG files served at full resolution from S3 without CDN optimization
Impact: 7.4s potential LCP savings + 940ms from proper sizing + additional savings from Cloudflare CDN
Priority: Critical

2. JavaScript Bundle Optimization¶

Issue: 2.4MB unused JavaScript causing 2.8s delay
Current: Large bundles with unused code
Impact: 2.8s potential FCP/LCP savings
Priority: High

3. Main Thread Blocking¶

Issue: 3.7s of main thread work blocking interaction
Current: Heavy JavaScript execution
Impact: Poor Time to Interactive scores
Priority: High

Implementation Plan¶

Phase 1: Image Optimization (Week 1)¶

Estimated Impact: 8+ second LCP improvement

1.1 API-Side WebP Conversion & S3 Optimization¶

Location: apps/api/ - Image upload/processing endpoints and S3 integration
Implementation:
Add WebP conversion on image upload for banner images AND show background images
Generate multiple sizes (responsive images) for all image types
Configure S3 bucket caching with proper headers
Implement Cloudflare CDN in front of S3 for global image delivery
Serve WebP with JPEG fallback
Add image compression pipeline for all image assets

1.2 Frontend Image Optimization¶

File: apps/frontend/src/app/shows/[slug]/page.tsx (lines 304-311, 249)

Current Code:

// Banner image (line 304-311)
<Image
  src={banner_image}
  alt={title}
  width={1200}
  height={600}
  className="w-full h-full object-cover"
/>

// Background image (line 249)
style={{
  backgroundImage: `url(${ticket_page_design?.[0]?.background_image})`,
  backgroundSize: 'cover',
  backgroundPosition: 'center',
}}

Optimizations:
Add priority prop for above-fold banner images
Convert background image to optimized Next.js Image component
Implement responsive image sizes for both banner and background
Add WebP format support with Cloudflare CDN URLs
Optimize loading strategy with proper cache headers

Phase 2: JavaScript Optimization (Week 2)¶

Estimated Impact: 2.8 second improvement

2.1 Code Splitting & Lazy Loading¶

Target: Component-level code splitting
Components to optimize:
TicketCheckoutForm - Load only when needed
VideoPlayer - Lazy load when video present
SocialShare - Defer loading
SEO components - Server-side only

2.2 Bundle Analysis & Tree Shaking¶

Tools: Next.js Bundle Analyzer
Focus: Remove unused dependencies
Target Libraries:
React Icons (tree-shake specific icons)
Form libraries (lazy load)
Third-party widgets

Phase 3: Core Web Vitals Optimization (Week 3)¶

Estimated Impact: Comprehensive performance improvement

3.1 Critical Resource Prioritization¶

Hero image: Add priority loading
Above-fold content: Inline critical CSS
Fonts: Optimize font loading strategy

3.2 Streaming & Progressive Enhancement¶

Server Components: Maximize SSR usage
Streaming: Implement progressive page loading
Hydration: Selective client-side hydration

Technical Implementation Details¶

WebP Conversion Implementation¶

API Changes (Django) - Enhanced for S3 Integration¶

Frontend Image Component Enhancement¶

// Optimized Image component for show banners with Cloudflare CDN
const OptimizedShowImage = ({ src, alt, title, priority = false }) => {
  // Convert S3 URL to Cloudflare CDN URL with WebP format
  const getCdnUrl = (originalUrl: string, width: number) => {

      <div className="relative z-10">
        {children}
      </div>
    </div>

JavaScript Optimization Strategy¶

Dynamic Imports for Heavy Components¶

import dynamic from 'next/dynamic';

// Lazy load ticket form
const TicketCheckoutForm = dynamic(
  () => import('@/components/Forms/tickets'),
  {
    loading: () => <TicketFormSkeleton />,
    ssr: false
  }
);

// Conditional video player loading
const VideoPlayer = dynamic(
  () => import('@/components/VideoPlayer'),
  { ssr: false }
);

// Lazy load social sharing
const SocialShare = dynamic(
  () => import('@/components/SocialShare'),
  {
    loading: () => <div className="h-8 bg-gray-200 animate-pulse rounded" />,
    ssr: false
  }
);

Bundle Splitting Configuration¶

// next.config.ts optimization
const nextConfig = {
  experimental: {
    optimizeCss: true,
  },
  images: {
    formats: ['image/webp', 'image/avif'],
    minimumCacheTTL: 60,
  },
  webpack: (config) => {
    config.optimization.splitChunks = {
      chunks: 'all',
      cacheGroups: {
        vendor: {
          test: /[\\/]node_modules[\\/]/,
          chunks: 'all',
          name: 'vendors',
        },
        common: {
          name: 'common',
          minChunks: 2,
          chunks: 'all',
          enforce: true,
        },
      },
    };
    return config;
  },
};

aws s3api put-bucket-policy --bucket piquetickets-images --policy '{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "CloudflareReadGetObject",
      "Effect": "Allow",
      "Principal": "*",
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::piquetickets-images/*"
    }
  ]
}'

# Configure CORS for Cloudflare
aws s3api put-bucket-cors --bucket piquetickets-images --cors-configuration '{
  "CORSRules": [
    {
      "AllowedOrigins": ["*"],
      "AllowedMethods": ["GET"],
      "AllowedHeaders": ["*"]
    }
  ]
}'

2. Cloudflare CDN Setup¶

# Add custom domain to Cloudflare (via Cloudflare Dashboard)
# 1. Add images.piquetickets.com as CNAME to piquetickets-images.s3.amazonaws.com
# 2. Enable Cloudflare proxy (orange cloud)
# 3. Configure Page Rules for optimal caching:

# Page Rule: images.piquetickets.com/*
# Settings:
# - Cache Level: Cache Everything
# - Edge Cache TTL: 1 year
# - Browser Cache TTL: 1 year
# - Always Use HTTPS: On

3. Cloudflare Image Optimization¶

// Cloudflare Worker for dynamic image optimization (optional)
addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request))
})

async function handleRequest(request) {
  const url = new URL(request.url)

  // Auto WebP conversion if browser supports it
  const acceptHeader = request.headers.get('Accept') || ''
  if (acceptHeader.includes('image/webp')) {
    url.searchParams.set('f', 'webp')
  }

  // Responsive sizing based on query params
  const width = url.searchParams.get('w')
  if (width) {
    url.searchParams.set('width', width)
  }

  const response = await fetch(url.toString())

  // Cache for 1 year
  const modifiedResponse = new Response(response.body, response)
  modifiedResponse.headers.set('Cache-Control', 'public, max-age=31536000, immutable')

  return modifiedResponse
}

4. Django Settings Configuration¶

# settings.py additions for S3 + Cloudflare optimization
AWS_STORAGE_BUCKET_NAME = 'piquetickets-images'
AWS_S3_REGION_NAME = 'us-east-1'

# Cloudflare CDN settings
CLOUDFLARE_CDN_DOMAIN = 'images.piquetickets.com'

# Optimized cache settings for S3
AWS_S3_OBJECT_PARAMETERS = {
    'CacheControl': 'public, max-age=31536000, immutable',  # 1 year cache
}

# Image optimization settings
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'
STATICFILES_STORAGE = 'storages.backends.s3boto3.StaticS3Boto3Storage'

# Custom domain for image serving
AWS_S3_CUSTOM_DOMAIN = CLOUDFLARE_CDN_DOMAIN

Next Steps¶

Immediate Action: Begin Phase 1 implementation with S3 + Cloudflare CDN setup
Infrastructure Setup: Configure S3 bucket and Cloudflare CDN
Team Alignment: Review plan with development team
Environment Setup: Prepare staging environment for testing
Baseline Establishment: Document current performance metrics
Implementation Start: Begin WebP conversion and S3 integration development

This comprehensive plan provides a systematic approach to achieving significant performance improvements on the PiqueTickets show page, targeting image optimization with S3 + Cloudflare CDN integration as the highest-impact optimization, while maintaining a safe deployment strategy.
