Este caso simple es manejado automáticamente por FastAPI porque la anotación del tipo de retorno es la clase (o una subclase de) `Response`.

Podrías cargarlo en el nivel superior del módulo/archivo, pero eso también significaría que **cargaría el modelo** incluso si solo estás ejecutando una simple prueba automatizada, entonces esa prueba sería **lenta** porque tendría que esperar a que el modelo se cargue antes de poder ejecutar una parte independiente del código.

## Create a TypeScript SDK { #create-a-typescript-sdk }

Let's start with a simple FastAPI application:

			return 'a'
		case unicode.IsDigit(r):
			return '0'
		case r == '_', r == '$':
			return r
		default:
			valid = false
			return -1
		}
	}, name)

	if valid {
		// check for simple name or quoted name
		// - letter/underscore followed by one or more letter/digit/underscore
		// - any text between quotes (text cannot contain a quote itself)
