Let's imagine that you have some **machine learning models** that you want to use to handle requests. 🤖

The same models are shared among requests, so, it's not one model per request, or one per user or something similar.

Let's imagine that loading the model can **take quite some time**, because it has to read a lot of **data from disk**. So you don't want to do it for every request.

 * It also manages document processing requests and integrates with the crawler system.

La *path operation* para `swagger_ui_redirect` es una herramienta cuando utilizas OAuth2.

It's very similar to a JSON array (equivalent of a Python list), but instead of being wrapped in `[]` and having `,` between the items, it has **one JSON object per line**, they are separated by a new line character.

            This will be used to extract the data and for the generated OpenAPI.
            It is particularly useful when you can't use the name you want because it

Luego podemos usar `secrets.compare_digest()` para asegurar que `credentials.username` es `"stanleyjobson"`, y que `credentials.password` es `"swordfish"`.

Esto sería similar a:

Para algunos tipos de aplicaciones, podrías querer agregar dependencias a toda la aplicación.

Similar a como puedes [agregar `dependencies` a los *path operation decorators*](dependencies-in-path-operation-decorators.md), puedes agregarlos a la aplicación de `FastAPI`.

En ese caso, se aplicarán a todas las *path operations* en la aplicación:
