### Injection de dépendances

FastAPI contient un système simple mais extrêmement puissant d'<abbr title='aussi connus sous le nom de "composants", "ressources", "services", "providers"'><strong>Injection de Dépendances</strong></abbr>.

* Même les dépendances peuvent avoir des dépendances, créant une hiérarchie ou un **"graph" de dépendances**

* L'utilisation de **contraintes de validation** comme `maximum_length` ou `regex`.
* Un **<abbr title="aussi connu sous le nom de composants, ressources, fournisseurs, services, injectables">système d'injection de dépendance </abbr>** très puissant et facile à utiliser .
