Pero ese archivo no existe, nuestras dependencias están en un archivo en `app/dependencies.py`.

Te contaré un poquito más sobre estos **conceptos** aquí, y eso, con suerte, te dará la **intuición** que necesitarías para decidir cómo implementar tu API en diferentes entornos, posiblemente incluso en aquellos **futuros** que aún no existen.

Al considerar estos conceptos, podrás **evaluar y diseñar** la mejor manera de implementar **tus propias APIs**.

En los próximos capítulos, te daré más **recetas concretas** para implementar aplicaciones de FastAPI.

- DRA device taints: `DeviceTaintRule` status provides information about the rule, including whether Pods still need to be evicted (`EvictionInProgress` condition). The newly added `None` effect can be used to preview what a `DeviceTaintRule` would do if it used the `NoExecute` effect and to taint devices (`device health`) without immediately affecting scheduling or running Pods....

Mais la documentation fait toujours défaut. C'est alors qu'APISpec a été créé.

Il s'agit d'un plug-in pour de nombreux frameworks (et il existe également un plug-in pour Starlette).

Le principe est le suivant : vous écrivez la définition du schéma au format YAML dans la docstring de chaque fonction gérant une route.

Et il génère des schémas OpenAPI.
