How to improve Content Painful Image Loading

Service Worker Implementation

• Create a service worker for efficient resource caching
• Add offline fallback support for better user experience
• Implement smart caching strategies for different resource types

Enhanced Lazy Loading

• Improve the lazy loading script to better prioritize above-the-fold content
• Add dynamic detection of LCP elements for priority loading
• Implement optimized fetching using requestAnimationFrame for smoother performance

Interaction to Next Paint (INP) Optimization

• Add specialized code to optimize responses to user interactions
• Improve touch and click event handling for better perceived performance
• Enhance menu and button interactions for faster response times

Third-Party Script Management

• Create a system to delay and control third-party script execution
• Implement intelligent script loading based on user interaction
• Add preconnect strategies to optimize connections to external domains

Browser Caching Configuration

• Create comprehensive browser caching rules
• Configure proper Cache-Control headers for all resource types
• Implement optimized cache durations for different file types

Performance Monitoring Dashboard

• Build an admin dashboard to monitor Core Web Vitals
• Integrate real-time performance measurement using the web-vitals library
• Implement automated performance scanning and recommendation tools

Documentation

• Create detailed documentation of all performance optimizations
• Provide maintenance tips and further optimization guidance
• Include server-level instructions for implementing browser caching
