Vue 3 スキル

Vue 3 Composition API、<script setup> マクロ、リアクティビティシステム、組み込みコンポーネントに関するスキル。Vue SFC 作成時、defineProps/defineEmits/defineModel、ウォッチャー、Transition/Teleport/Suspense/KeepAlive 使用時に活用します。

Vue 3 スキル とは?

このスキルは、Vue 3(バージョン 3.5 ベース)を使用してフロントエンドアプリケーションを開発する際に、AI アシスタントが一貫性のあるベストプラクティスに従ってコードを生成・支援するためのスキルです。Composition API と `<script setup lang='ts'>` を強く推奨し、TypeScript の使用、パフォーマンス向上のための `shallowRef` の活用、Options API の回避など、具体的な設定項目を定義しています。スキルは、Script Setup とそのマクロ(defineProps、defineEmits、defineModel など)、リアクティビティとライフサイクル(ref、computed、watch、effectScope など)、および組み込みコンポーネントとディレクティブ(Transition、Teleport、Suspense、KeepAlive、v-memo など)の3つの主要トピックをカバーしています。Vue 3 を使用するあらゆる開発環境(Claude Code, Cursor, Codex 等)で利用可能で、AI エージェントがプロジェクトのコーディング規約に沿った適切なコードを提案し、開発効率を向上させます。

ドキュメント

Vue

Vue 3.5 に基づいています。常に Composition API と <script setup lang="ts"> を使用してください。

設定項目

  • JavaScript よりも TypeScript を優先する
  • <script> よりも <script setup lang="ts"> を優先する
  • パフォーマンスのために、深いリアクティビティが必要ない場合は ref よりも shallowRef を優先する
  • 常に Options API よりも Composition API を使用する
  • リアクティブな Props の分割代入(Destructure)は推奨しない

コンポーネントテンプレート

<script setup lang="ts">
import { ref, computed, watch, onMounted } from 'vue'

const props = defineProps<{
  title: string
  count?: number
}>()

const emit = defineEmits<{
  update: [value: string]
}>()

const model = defineModel<string>()

const doubled = computed(() => (props.count ?? 0) * 2)

watch(() => props.title, (newVal) => {
  console.log('Title changed:', newVal)
})

onMounted(() => {
  console.log('Component mounted')
})
</script>

<template>
  <div>{{ title }} - {{ doubled }}</div>
</template>
