Vue 3 Development

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

Current stable: Vue 3.5+ with enhanced reactivity performance (-56% memory, 10x faster array tracking), new SSR features, and improved developer experience.

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 For VueUse composables: use vueuse 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 | | TypeScript patterns | references/typescript.md | | Vue Router typing | references/router.md | | Reactivity (ref, watch) | references/reactivity.md | | Custom directives | references/directives.md | | Provide/inject | references/provide-inject.md | | Edge cases, vue-tsc | references/gotchas.md |

Loading Files

Consider loading these reference files based on your task:

• [ ] references/components.md - if working in components/ or writing .vue files
• [ ] references/composables.md - if creating composables (use* functions)
• [ ] references/utils-client.md - if working in utils/ or writing client utilities
• [ ] references/testing.md - if writing .spec.ts or .test.ts files
• [ ] references/typescript.md - if working with Vue TypeScript patterns or generics
• [ ] references/router.md - if working with Vue Router or route typing
• [ ] references/reactivity.md - if using ref, reactive, computed, watch, or watchEffect
• [ ] references/directives.md - if creating or using custom directives
• [ ] references/provide-inject.md - if using provide/inject patterns
• [ ] references/gotchas.md - if debugging edge cases or hydration issues

DO NOT load all files at once. Load only what's relevant to your current task.

Quick Start

<script setup lang="ts">
const { count = 0 } = defineProps<{ count?: number }>()
const emit = defineEmits<{ update: [value: number] }>()
</script>

<template>
  <button @click="emit('update', count + 1)">
    Count: {{ count }}
  </button>
</template>

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, reactivity gotchas

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, router mocking

references/typescript.md - InjectionKey for provide/inject, vue-tsc strict templates, tsconfig settings, generic components

references/router.md - Route meta types, typed params with unplugin-vue-router, scroll behavior, navigation guards

references/reactivity.md - ref, reactive, computed, watch, watchEffect, reactivity fundamentals

references/directives.md - Custom directive hooks, v-focus, v-click-outside, v-tooltip patterns

references/provide-inject.md - InjectionKey typing, app-level provide, readonly patterns

references/gotchas.md - Common gotchas, vue-tsc edge cases, hydration issues, race conditions (from vuejs-ai/skills)
