    * Dockerマルチステージビルド。コンパイルされたコードの保存やコミットが不要。
    * ビルド時にフロントエンドテスト実行 (無効化も可能)。
    * 可能な限りモジュール化されているのでそのまま使用できますが、Vue CLIで再生成したり、必要に応じて作成したりして、必要なものを再利用可能。
* PostgreSQLデータベースのための**PGAdmin**。(PHPMyAdminとMySQLを使用できるように簡単に変更可能)
* Celeryジョブ監視のための**Flower**。
* **Traefik**を使用してフロントエンドとバックエンド間をロードバランシング。同一ドメインに配置しパスで区切る、ただし、異なるコンテナで処理。
* Traefik統合。Let's Encrypt **HTTPS**証明書の自動生成を含む。
* GitLab **CI** (継続的インテグレーション)。フロントエンドおよびバックエンドテストを含む。

Here we'll see an example using <a href="https://www.sqlalchemy.org/" class="external-link" target="_blank">SQLAlchemy</a>.

You can easily adapt it to any database supported by SQLAlchemy, like:

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server, etc.

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.
