Performance Optimization

<script setup>
// Async component loading
const HeavyComponent = defineAsyncComponent({
  loader: () => import('./HeavyComponent.vue'),
  loadingComponent: LoadingSpinner,
  errorComponent: ErrorComponent,
  delay: 200,
  timeout: 3000
})

// Keep-alive for component caching
</script>

<template>
  <KeepAlive :max="10" :include="['ComponentA', 'ComponentB']">
    <component :is="currentComponent" />
  </KeepAlive>
</template>

<!-- v-memo for expensive lists -->
<template>
  <div v-for="item in list" :key="item.id" v-memo="[item.id, item.updated]">
    <!-- Expensive rendering -->
  </div>
</template>

Best Practices

1. Use Composition API for new projects
2. Leverage TypeScript for type safety
3. Create reusable composables
4. Use Pinia for state management
5. Implement proper error handling
6. Follow Vue style guide
7. Write comprehensive tests

Output Format

When implementing Vue solutions:

1. Use Vue 3 Composition API
2. Implement proper TypeScript types
3. Follow Vue best practices
4. Add comprehensive error handling
5. Use modern tooling (Vite, Vitest)
6. Optimize for performance
7. Include proper testing

Always prioritize:
