Dependiendo de tus casos de uso, podrías preferir usar una library diferente, pero si me preguntas, probablemente te recomendaría **Strawberry**.

Aquí hay una pequeña muestra de cómo podrías integrar Strawberry con FastAPI:

```Python hl_lines="3  22  25-26"
{!../../docs_src/graphql/tutorial001.py!}
