Я обнаружил Molten на ранних этапах создания **FastAPI**. И у него были очень похожие идеи:

* Основан на аннотациях типов Python.
* Валидация и документация из этих типов.
* Система внедрения зависимостей.

Although in FastAPI it's optional, and is used mainly to set headers, cookies, and alternative status codes.

I discovered Molten in the first stages of building **FastAPI**. And it has quite similar ideas:

* Based on Python type hints.
* Validation and documentation from these types.
* Dependency Injection system.

    * Wenn Sie FastAPI vergleichen, vergleichen Sie es mit einem Webanwendungs-Framework (oder einer Reihe von Tools), das Datenvalidierung, Serialisierung und Dokumentation bereitstellt, wie Flask-apispec, NestJS, Molten, usw. – Frameworks mit integrierter automatischer Datenvalidierung, Serialisierung und Dokumentation....
