# Größere Anwendungen – mehrere Dateien { #bigger-applications-multiple-files }

Wenn Sie eine Anwendung oder eine Web-API erstellen, ist es selten der Fall, dass Sie alles in einer einzigen Datei unterbringen können.

**FastAPI** bietet ein praktisches Werkzeug zur Strukturierung Ihrer Anwendung bei gleichzeitiger Wahrung der Flexibilität.

Wenn Sie von Flask kommen, wäre dies das Äquivalent zu Flasks Blueprints.

Deberías añadir tests para tu aplicación.

Con **FastAPI** es muy fácil (gracias a Starlette), revisa la documentación: [Escribir pruebas](../tutorial/testing.md)

Ensuite votre API va (imaginons) :

* Envoyer la facture à un client de la personne développeuse externe.
* Encaisser l’argent.
* Renvoyer une notification à l’utilisateur de l’API (la personne développeuse externe).
    * Cela sera fait en envoyant une requête POST (depuis *votre API*) vers une *API externe* fournie par cette personne développeuse externe (c’est le « callback »).
