SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps frontend developers learn and apply Vue 3 composition API patterns, simplifying the creation of scalable components and applications.

Core Features & Use Cases

Script setup & macros: use defineProps, defineEmits, defineModel, and defineExpose to build clean SFCs.
Reactivity & lifecycle: manage refs, computed, watch, and lifecycle hooks for robust UI logic.
Use Case: Build a reusable component library or SPA with clear composition API patterns in Vue 3.5+.

Quick Start

Provide a modern Vue 3 environment and follow the included examples to structure an SFC using the script setup syntax and composition API.

FAQPage Schema

How do I use the Vue 3 composition API with script setup to build scalable components?▼

Use the Vue 3 composition API with script setup to define components using defineProps, defineEmits, and defineModel macros. This pattern simplifies SFC creation, manages reactivity through refs and computed properties, and structures modular UI logic for scalable single-page applications.

What is the best way to manage reactivity and lifecycle hooks in a Vue 3 component?▼

Manage reactivity and lifecycle hooks in a Vue 3 component by utilizing refs, computed values, and watch functions within the script setup block. This approach ensures robust UI logic handling throughout the component's lifecycle in a modern TypeScript-supported environment.

Do I need TypeScript and Vite to build a Vue 3 application with the composition API?▼

A modern Vue 3 environment requires TypeScript support and Vite-based tooling integration to effectively utilize the composition API and script setup syntax. This setup ensures proper type checking and bundling for building modular components and design systems.

Can I use defineModel and defineExpose to build a reusable component library in Vue 3.5+?▼

Use defineModel and defineExpose macros in Vue 3.5+ to create clear SFC interfaces for a reusable component library. These script setup macros allow precise control over component state exposure and two-way binding, essential for scalable design systems.

Why does structuring single-file components with the composition API improve Vue 3 SPAs?▼

Structuring single-file components with the composition API improves Vue 3 SPAs by grouping related logic cohesively. Using script setup alongside reactivity patterns replaces fragmented options, resulting in maintainable and modular components for complex frontend applications.
