すべての箇所で、すべての開発者に最高の開発体験を提供しました。

## 要件

いくつかの代替手法を試したあと、私は<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">**Pydantic**</a>の強みを利用することを決めました。

そして、JSON Schemaに完全に準拠するようにしたり、制約宣言を定義するさまざまな方法をサポートしたり、いくつかのエディターでのテストに基づいてエディターのサポート (型チェック、自動補完) を改善するために貢献しました。

開発中、もう1つの重要な鍵となる<a href="https://www.starlette.io/" class="external-link" target="_blank">**Starlette**</a>、にも貢献しました。
