SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Vue 3 provides a robust framework for building user interfaces using the Composition API, script setup macros, and a reactivity system. It clarifies how to structure SFCs, define props and emits, and leverage built-in components for scalable UI development.

Core Features & Use Cases

  • Use when creating Vue SFCs with <script setup>, defineProps, defineEmits, and defineModel for clean, typed components.
  • Leverage built-in components and reactivity utilities to manage complex UI with minimal boilerplate.
  • Apply best practices across small to large apps, including transitions, dynamic components, and lifecycle hooks.

Quick Start

Set up a Vue 3 component using the script setup syntax to access props, emits, and reactive state.

FAQPage Schema
How do I define typed props and emits in a Vue 3 SFC?

You define typed props and emits in a Vue 3 SFC using the script setup macros defineProps and defineEmits. This approach leverages TypeScript to provide strict type checking for component inputs and outputs, reducing boilerplate.

Can I use the Composition API with script setup for large applications?

Yes, the Composition API with script setup is designed for large applications. It helps structure SFCs by organizing component logic into composable functions, managing complex reactive state, and integrating built-in components with minimal boilerplate.

What is the best way to manage reactivity in Vue 3 components?

The best way to manage reactivity in Vue 3 components is by using the Composition API's reactivity utilities alongside script setup. This combination allows you to track mutable state and handle dynamic UI updates cleanly within your SFCs.

Do I need TypeScript to use Vue 3 script setup macros?

TypeScript is not strictly required to use script setup macros, but it is highly recommended. The Skill assumes a project configured for Vue SFCs with TypeScript to fully leverage typed props, emits, and defineModel for scalable development.

How do I handle dynamic components and lifecycle hooks in Vue 3 SFCs?

You handle dynamic components and lifecycle hooks in Vue 3 SFCs by applying Composition API best practices. Using script setup, you can directly import built-in components and register lifecycle hooks to manage transitions and complex UI behavior.

Why standardize Vue 3 component development with the Composition API?

Standardizing Vue 3 component development with the Composition API solves structural complexity by clarifying how to organize SFCs. It replaces confusing logic patterns with a straightforward integration of reactivity and built-in components for scalable UI.
