Overview

Implement performance optimization strategies including lazy loading, code splitting, caching, compression, and monitoring to improve Core Web Vitals and user experience.

When to Use

• Slow page load times
• High Largest Contentful Paint (LCP)
• Large bundle sizes
• Frequent Cumulative Layout Shift (CLS)
• Mobile performance issues

Quick Start

Minimal working example:

// utils/lazyLoad.ts
import React from 'react';

export const lazyLoad = (importStatement: Promise<any>) => {
  return React.lazy(() =>
    importStatement.then(module => ({
      default: module.default
    }))
  );
};

// routes.tsx
import { lazyLoad } from './utils/lazyLoad';

export const routes = [
  {
    path: '/',
    component: () => import('./pages/Home'),
    lazy: lazyLoad(import('./pages/Home'))
  },
  {
    path: '/dashboard',
    lazy: lazyLoad(import('./pages/Dashboard'))
  },
  {
// ... (see reference guides for full implementation)
