SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers efficiently build modern Vue.js applications by leveraging the Composition API, script setup, and advanced reactivity patterns.

Core Features & Use Cases

  • Composition API: Write cleaner, more organized, and reusable component logic.
  • Script Setup: Simplify component structure with top-level bindings and automatic exposure.
  • Reactivity: Understand and utilize ref, computed, watch, and shallowRef for dynamic UIs.
  • Built-in Components: Master Transition, Teleport, Suspense, and KeepAlive for enhanced user experiences.
  • Use Case: When building a complex form with multiple interdependent fields and asynchronous data loading, use this Skill to structure your component logic effectively with Composition API and script setup.

Quick Start

Use the vue skill to generate a basic Vue 3 component using <script setup lang="ts"> and defineProps.

FAQPage Schema
How do I use the Vue 3 Composition API to structure component logic?

Use the Vue 3 Composition API to organize component logic by leveraging `script setup`, `refs`, and `computed` properties for cleaner, more maintainable code. It simplifies top-level bindings and automatic exposure.

What is the difference between ref and shallowRef for Vue reactivity?

`ref` creates deep reactivity for dynamic UIs, whereas `shallowRef` provides shallow reactivity. Use `shallowRef` to avoid deep tracking of large objects, optimizing Vue application performance.

How do I handle asynchronous data loading with Suspense in Vue?

Handle asynchronous data loading in Vue by using the `Suspense` built-in component. It manages fallback states while waiting for nested async dependencies to resolve during component rendering.

When should I use the Teleport component in Vue 3?

Use the `Teleport` component in Vue 3 when you need to render a piece of UI outside the current DOM hierarchy. It enhances user experiences by projecting modals or overlays to a different DOM node.

Does script setup support defineProps for Vue component properties?

Yes, `script setup` supports `defineProps` to declare component properties. This syntax simplifies the Vue component structure by providing top-level bindings and automatic exposure without boilerplate.

Best way to manage transitions between Vue components?

The best way to manage transitions is by using the Vue `Transition` and `KeepAlive` built-in components. `Transition` handles enter and leave effects, while `KeepAlive` caches component state to avoid re-rendering.
