Por supuesto, hay algunos casos en los que no hay problema en ejecutar los pasos previos múltiples veces, en ese caso, es mucho más fácil de manejar.

/// tip | Consejo

También, ten en cuenta que dependiendo de tu configuración, en algunos casos **quizás ni siquiera necesites realizar pasos previos** antes de iniciar tu aplicación.

Gardez à l'esprit que vous devez renvoyer directement `JSONResponse`.

/// info

La clé `model` ne fait pas partie d'OpenAPI.

**FastAPI** prendra le modèle Pydantic à partir de là, générera le `JSON Schema` et le placera au bon endroit.

Le bon endroit est :

     *
     * @param thumbnailId the identifier for the thumbnail being generated
     * @param cmdList the list of command arguments to execute
     * @return the exit code of the process if it finishes normally; -1 if the process fails or is terminated

O **FastAPI** possui um poderoso, mas intuitivo sistema de **<dfn title="também conhecida como componentes, recursos, provedores, serviços, injetáveis">Injeção de Dependência</dfn>**.

Esse sistema foi pensado para ser fácil de usar, e permitir que qualquer desenvolvedor possa integrar facilmente outros componentes ao **FastAPI**.

**FastAPI** est entièrement compatible avec (et basé sur) [**Starlette**](https://www.starlette.dev/). Donc, tout code Starlette additionnel que vous avez fonctionnera aussi.

`FastAPI` est en fait une sous-classe de `Starlette`. Ainsi, si vous connaissez ou utilisez déjà Starlette, la plupart des fonctionnalités fonctionneront de la même manière.
