export default User;推論されたスキーマフィールド
26 プロパティ
ネストされたサブドキュメント
3 子スキーマ
検出されたBSON型
AddressSchema, Boolean, Date, Number, PreferencesSchema, ProfileSchema, String
100%ブラウザ内推論
JSONの構造解析と型推論はブラウザ内で完結し、サーバーへのデータ送信は一切行われません。
デュアルスタックコード生成
Mongooseスキーマ、TypeScript Document型、純粋なDTOインターフェース、Zodバリデーションスキーマを一括生成。
本番向けMongooseベストプラクティス
自動タイムスタンプ、ObjectId参照、文字列trim、インデックス設定、サブドキュメントの_id制御に対応。
