Vue 3 Development

Reference for Vue 3 Composition API patterns, component architecture, and testing practices.

Overview

Progressive reference system for Vue 3 projects. Load only files relevant to current task to minimize context usage (~250 tokens base, 500-1500 per sub-file).

When to Use

Use this skill when:

• Writing .vue components
• Creating composables (use* functions)
• Building client-side utilities
• Testing Vue components/composables

Use nuxt skill instead for:

• Server routes, API endpoints
• File-based routing, middleware
• Nuxt-specific patterns

For styled UI components: use nuxt-ui skill For headless accessible components: use reka-ui skill

Quick Reference

Working on...	Load file
.vue in components/	references/components.md
File in composables/	references/composables.md
File in utils/	references/utils-client.md
.spec.ts or .test.ts	references/testing.md

Loading Files

Load one file at a time based on file context:

• Component work → references/components.md
• Composable work → references/composables.md
• Utils work → references/utils-client.md
• Testing → references/testing.md

DO NOT load all files at once - wastes context on irrelevant patterns.

Available Guidance

references/components.md - Props with reactive destructuring, emits patterns, defineModel for v-model, slots shorthand

references/composables.md - Composition API structure, VueUse integration, lifecycle hooks, async patterns

references/utils-client.md - Pure functions, formatters, validators, transformers, when NOT to use utils

references/testing.md - Vitest + @vue/test-utils, component testing, composable testing, mocking patterns

Examples

Working examples in resources/examples/:

• component-example.vue - Full component with all patterns
• composable-example.ts - Reusable composition function
