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
