## Совместимость с **FastAPI** { #fastapi-compatibility }

Простота системы **Dependency Injection** делает **FastAPI** совместимым с:

* всеми реляционными базами данных
* NoSQL базами данных
* внешними пакетами
* внешними API

## Compatibilidade do **FastAPI** { #fastapi-compatibility }

A simplicidade do sistema de injeção de dependência do **FastAPI** faz ele compatível com:

* todos os bancos de dados relacionais
* bancos de dados NoSQL
* pacotes externos
* APIs externas
