Frontend Performance Optimization: Advanced Techniques for Lightning-Fast Apps

Modern Performance Optimization

Frontend performance optimization goes beyond basic minification and compression.

Core Web Vitals Optimization

• Largest Contentful Paint (LCP): Optimize image loading and critical rendering path
• First Input Delay (FID): Minimize JavaScript execution time and main thread blocking
• Cumulative Layout Shift (CLS): Prevent unexpected layout shifts with proper sizing
• Interaction to Next Paint (INP): Optimize event handler performance

Advanced Loading Strategies

Implement route-based and component-based code splitting using dynamic imports.

Caching and Delivery

Implement service workers for offline functionality and sophisticated caching strategies.
