Portanto, você vai querer ter um **processo único** para executar essas **etapas anteriores** antes de iniciar o aplicativo.

    * Se você também declarar dependências em uma *operação de rota* específica, **elas também serão executadas**.
    * As dependências do roteador são executadas primeiro, depois as [`dependencies` no decorador](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank} e, em seguida, as dependências de parâmetros normais.

### Flask REST frameworks { #flask-rest-frameworks }

Existem vários Flask REST frameworks, mas depois de investir tempo e trabalho investigando-os, descobri que muitos estão descontinuados ou abandonados, com diversas questões em aberto que os tornaram inadequados.

// 2 tools for doing the mapping
// 3 the component model -> interfaces for the plugin

// The plugin manager should load up a directory structure of plugins.
// - a plugin per directory where the plugin is present with its deps
// - a plugin that has its dependencies packaged up with it
// - implement filters and create a test where a plugin fails if the right classes are not filtered

Antes de implantar, certifique-se de que está autenticado:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Depois, implemente sua aplicação:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

précédents, en utilisant des fonctionnalités du langage qui n'étaient même pas disponibles auparavant (type hints depuis Python 3.6+).
