    But because **FastAPI** is based on the Python standards, including `Annotated`, you can use this trick in your code. 😎

The dependencies will keep working as expected, and the **best part** is that the **type information will be preserved**, which means that your editor will be able to keep providing you with **autocompletion**, **inline errors**, etc. The same for other tools like `mypy`.

    * Verifica que tem um atributo obrigatório `name` que deve ser `str`.
    * Verifica que tem um atributo obrigatório `price` que deve ser `float`.
    * Verifica que tem an atributo opcional `is_offer`, que deve ser `bool`, se presente.
    * Tudo isso também funciona para objetos JSON profundamente aninhados.
* Converter de e para JSON automaticamente.
* Documentar tudo com OpenAPI, que poderá ser usado por:
    * Sistemas de documentação interativos.

Then the next question would be, why not just connect and disconnect the database in the `async` dependency itself, instead of in `get_db()`?

The `async` dependency has to be `async` for the context variable to be preserved for the rest of the request, but creating and closing the database connection is potentially blocking, so it could degrade performance if it was there.

#### Docker Compose

Você pode estar implantando em um **único servidor** (não em um cluster) com o **Docker Compose**, então você não teria uma maneira fácil de gerenciar a replicação de contêineres (com o Docker Compose) enquanto preserva a rede compartilhada e o **balanceamento de carga**.

Então você pode querer ter **um único contêiner** com um **gerenciador de processos** iniciando **vários processos trabalhadores** dentro.

    Because it uses `./poetry.lock*` (ending with a `*`), it won't crash if that file is not available yet.

5. Generate the `requirements.txt` file.

6. This is the final stage, anything here will be preserved in the final container image.

7. Set the current working directory to `/code`.

8. Copy the `requirements.txt` file to the `/code` directory.
