Vue
The skill is based on Vue 3.5+, generated at 2026-01-28.
Vue is a progressive JavaScript framework for building user interfaces. It builds on standard HTML, CSS, and JavaScript with intuitive API and world-class documentation. The Composition API with <script setup> and TypeScript is the recommended approach for building Vue applications.

Key Recommendations
- Use
<script setup lang="ts">for all components - Prefer
ref()overreactive()for declaring state - Use type-based prop declarations with interfaces
- Use
defineModel()for v-model (3.4+) - Destructure props reactively (3.5+) for cleaner code
- Extract composables for reusable stateful logic
