Core Web Vitals in React: From Red to Green in a Weekend

Google's Core Web Vitals directly impact your search ranking and user experience. The three metrics that matter most:

• LCP (Largest Contentful Paint): How fast your main content loads
• INP (Interaction to Next Paint): How responsive your app feels
• CLS (Cumulative Layout Shift): How stable your layout is

Quick wins for React apps: 1. Lazy load below-the-fold components with React.lazy() 2. Use priority hints for critical images 3. Avoid layout shifts with explicit dimensions 4. Debounce expensive re-renders with useDeferredValue 5. Preload critical fonts and data
