# Abhängigkeiten

**FastAPI** hat ein sehr mächtiges, aber intuitives **<abbr title="Dependency Injection – Einbringen von Abhängigkeiten: Auch bekannt als Komponenten, Ressourcen, Provider, Services, Injectables">Dependency Injection</abbr>** System.

Es ist so konzipiert, sehr einfach zu verwenden zu sein und es jedem Entwickler sehr leicht zu machen, andere Komponenten mit **FastAPI** zu integrieren.

## Was ist „Dependency Injection“

# Зависимости

**FastAPI** имеет очень мощную и интуитивную систему **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>**.

Она проектировалась таким образом, чтобы быть простой в использовании и облегчить любому разработчику интеграцию других компонентов с **FastAPI**.
