Це був один із перших надзвичайно швидких фреймворків Python на основі `asyncio`. Він був дуже схожий на Flask.

!!! note "Технічні деталі"

    * もしStarletteを比較する場合は、Sanic、Flask、DjangoなどのWEBフレームワーク (もしくはマイクロフレームワーク) と比較してください。
* **FastAPI**:
    * StarletteがUvicornを使っているのと同じで、**FastAPI**はStarletteを使っており、それより速くできません。
    * FastAPIはStarletteの上にさらに多くの機能を提供します。データの検証やシリアライゼーションなど、APIを構築する際に常に必要な機能です。また、それを使用することで、自動ドキュメント化を無料で取得できます (ドキュメントは実行中のアプリケーションにオーバーヘッドを追加せず、起動時に生成されます) 。

    Güçlü bir bağımlılık enjeksiyon sistemine sahip olmalı. Kod tekrarını minimuma indirecek bir yol bulmalı.

Sanic, `asyncio`'ya dayanan son derece hızlı Python kütüphanelerinden biriydi. Flask'a epey benzeyecek şekilde geliştirilmişti.

!!! note "Teknik detaylar"

    Usar tipos Python para ter um ótimo suporte do editor.

    Ter um sistema de injeção de dependência poderoso. Achar um jeito de minimizar repetição de código.
