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() over reactive() 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
