### Importar `FastAPI`

Importas y creas una clase `FastAPI` como de costumbre.

Y podemos incluso declarar [dependencias globales](dependencies/global-dependencies.md){.internal-link target=_blank} que se combinarán con las dependencias para cada `APIRouter`:

```Python hl_lines="1  3  7" title="app/main.py"
{!../../docs_src/bigger_applications/app/main.py!}
```

### Importar `FastAPI`

Você importa e cria uma classe `FastAPI` normalmente.

E podemos até declarar [dependências globais](dependencies/global-dependencies.md){.internal-link target=_blank} que serão combinadas com as dependências para cada `APIRouter`:

```Python hl_lines="1  3  7" title="app/main.py"
{!../../docs_src/bigger_applications/app/main.py!}

	switch kind, _ := crypto.IsEncrypted(metadata); kind {
	case crypto.S3:
		if GlobalKMS == nil {
			return nil, errKMSNotConfigured
		}
		objectKey, err := crypto.S3.UnsealObjectKey(GlobalKMS, metadata, bucket, object)
		if err != nil {
			return nil, err
		}
		return objectKey[:], nil
	case crypto.S3KMS:
		if GlobalKMS == nil {
			return nil, errKMSNotConfigured
		}
