Aquele commando por linha de programa chamado `fastapi` é o **FastAPI CLI**.

O FastAPI CLI recebe o caminho do seu programa Python, detecta automaticamente a variável com o FastAPI (comumente nomeada `app`) e como importá-la, e então a serve.

Para produção você usaria `fastapi run` no lugar. 🚀

To serve this configuration the server needs to provide its clients with a chain of certificates
starting with its own and including everything up-to but not including the root. We don't need to

## Deployment Concepts { #deployment-concepts }

Here you saw how to use multiple **workers** to **parallelize** the execution of the application, take advantage of **multiple cores** in the CPU, and be able to serve **more requests**.

From the list of deployment concepts from above, using workers would mainly help with the **replication** part, and a little bit with the **restarts**, but you still need to take care of the others:

{* ../../docs_src/query_params_str_validations/tutorial002.py hl[9] *}

Note que substituímos o valor padrão de `None` para `Query(default=None)`, o primeiro parâmetro de `Query` serve para o mesmo propósito: definir o valor padrão do parâmetro.

Então:

```Python
q: Union[str, None] = Query(default=None)
```

...Torna o parâmetro opcional, da mesma maneira que:

```Python
