SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Vue 3's Composition API and script setup simplify building scalable, reactive user interfaces by enabling a clean, reusable pattern for state, props, and lifecycle logic.

Core Features & Use Cases

  • Script setup macros for props (defineProps), emits (defineEmits), models (defineModel), and slots to improve type safety and DX.
  • Built-in components and directives (Transition, Teleport, Suspense, KeepAlive, v-memo) to enable rich, performant UIs.
  • Use cases include creating reusable single-file components, implementing complex reactivity patterns with ref/reactive, and composing modular frontend architectures.

Quick Start

Create a Vue 3 SFC using script setup and defineProps/defineEmits to render a simple interactive component.

FAQPage Schema
How do I build reactive UIs with Vue 3 and the Composition API?

Vue 3 builds reactive UIs using the Composition API and script setup syntax to manage state, props, and lifecycle logic in reusable single-file components. You use ref and reactive utilities to implement interactive frontend architectures cleanly.

How do I define props and emits in Vue 3 single-file components?

You define props and emits in Vue 3 single-file components using the defineProps and defineEmits script setup macros. These compiler macros improve type safety and developer experience without runtime imports.

When should I use built-in components like Transition and Teleport in Vue 3?

Use built-in components like Transition and Teleport in Vue 3 when building rich, performant UIs. Transition manages animation states, while Teleport renders DOM content outside the current component hierarchy to avoid layout conflicts.

Does Vue 3 script setup support two-way binding for component models?

Vue 3 script setup supports two-way binding through the defineModel macro. This allows parent and child components to synchronize state seamlessly, improving type safety and developer experience for reusable components.

What is the best way to compose modular frontend architectures in Vue 3?

The best way to compose modular frontend architectures in Vue 3 is using the Composition API with script setup. This pattern enables clean, reusable logic for state, props, and lifecycle hooks within single-file components without structural duplication.

Do I need prior knowledge of reactivity utilities to use Vue 3 script setup?

Yes, using Vue 3 script setup requires knowledge of Vue 3 concepts and reactivity utilities like ref and reactive. This prerequisite knowledge is necessary to implement and integrate single-file components effectively.
