To write Vue 3 components using the Composition API and script setup, use the `<script setup>` syntax in your single-file components to define reactive patterns and component logic concisely. This approach provides a cleaner structure for maintainable SFCs.

The best way to structure strongly typed single-file components in Vue 3 is by using compiler macros like defineProps, defineEmits, defineModel, and defineExpose within your script setup block to enforce strict typing and consistent reactivity patterns.

Yes, Vue 3 Composition API works seamlessly with built-in components like Teleport, Suspense, Transition, and KeepAlive. You can integrate these built-in features within your script setup for advanced UI rendering and asynchronous component handling.

Use defineModel instead of defineEmits in Vue 3 when you need two-way binding for form inputs or child components. defineModel simplifies reactive state synchronization, whereas defineEmits is better suited for one-way event notifications to parent components.

defineExpose works with reactivity patterns in Vue 3 script setup by explicitly exposing specific properties or methods from a child component to its parent. This allows parent components to access selected reactive state without exposing the entire component instance.
