#### Использовать `Union` или `Optional` { #using-union-or-optional }

Если вы используете версию Python ниже 3.10, вот совет с моей весьма **субъективной** точки зрения:

* 🚨 Избегайте использования `Optional[SomeType]`

I love to hear about how **FastAPI** is being used, what you have liked in it, in which project/company are you using it, etc.

## Vote for FastAPI { #vote-for-fastapi }

        // We want to eliminate any relative path nonsense and lock down the path so we
        // need to fully resolve it before any submodules use the path. This can happen
        // when you are using a custom settings.xml that contains a relative path entry
        // for the local repository setting.

        File localRepository = new File(url.substring("file://".length()));

                                if (managedVersions.containsKey(childKey)) {
                                    // If this child node is a managed dependency, ensure
                                    // we are using the dependency management version
                                    // of this child if applicable b/c we want to use the
                                    // managed version's POM, *not* any other version's POM.

Cuando creas una dependencia con `yield`, **FastAPI** creará internamente un context manager para ella y lo combinará con algunas otras herramientas relacionadas.

### Usando context managers en dependencias con `yield` { #using-context-managers-in-dependencies-with-yield }

/// warning | Advertencia

Esto es, más o menos, una idea "avanzada".

Si apenas estás comenzando con **FastAPI**, podrías querer omitirlo por ahora.
