Pinia

Vue公式の状態管理ライブラリ。型安全で拡張性が高く、ストアの定義やstate/getters/actionsの操作、Vueアプリでのストアパターン実装に使用します。

Pinia とは？

PiniaはVueの公式状態管理ライブラリであり、直感的で型安全なAPIを提供します。Options APIとComposition APIの両方に対応し、ファーストクラスのTypeScriptサポートと開発者ツール連携を備えています。このスキルは、ストアの定義、state/getters/actionsの操作、プラグインによる拡張、コンポーザブルやストア間の連携、テスト、SSR、Nuxt統合、HMRなどの高度なトピックをカバーしています。Vueアプリケーションにおいて、複雑なロジックにはSetup Storesを推奨し、リアクティビティを維持するために`storeToRefs()`を使用するなどのベストプラクティスが提供されています。Claude CodeやCursorなどのAIエージェントが、Vueプロジェクトで状態管理を簡単かつ堅牢に実装するためのガイドとして利用できます。

主な推奨事項

  • 複雑なロジック、コンポーザブル、ウォッチャーにはSetup Storesを推奨
  • state/gettersを分割代入するときはstoreToRefs()を使用してリアクティビティを維持
  • actionsは直接分割代入可能 - ストアにバインドされています
  • SSRの場合は特に、モジュールスコープではなく関数内でストアを呼び出す
  • 各ストアにHMRサポートを追加して開発体験を向上
  • コンポーネントテストでは@pinia/testingを使用してモックストアを実現
