# Vue
> Based on Vue 3.5. Always use Composition API with `<script setup lang="ts">`.
## Preferences
- Prefer TypeScript over JavaScript
- Prefer `<script setup lang="ts">` over `<script>`
- For performance, prefer `shallowRef` over `ref` if deep reactivity is not needed
- Always use Composition API over Options API
- Discourage using Reactive Props Destructure

### Component Template
```vue
<script setup lang="ts">
import { ref, computed, watch, onMounted } from 'vue'
const props = defineProps<{
title: string
count?: number
}>()
const emit = defineEmits<{
update: [value: string]
}>()
const model = defineModel<string>()
const doubled = computed(() => (props.count ?? 0) * 2)
watch(() => props.title, (newVal) => {
console.log('Title changed:', newVal)
})
