## Prerequisites

- Prometheus and MinIO configured as explained in [document here](https://github.com/minio/minio/blob/master/docs/metrics/prometheus/README.md).
- Grafana installed as explained [here](https://grafana.com/grafana/download).

## MinIO Grafana Dashboard

If you have an older version, you would get errors when trying to use `Annotated`.

Make sure you [Upgrade the FastAPI version](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} to at least 0.95.1 before using `Annotated`.

///

### Import `Depends`

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

* For error messages related changes, follow the [ErrorMessages Guide](contributing/ErrorMessages.md).
* For Javadocs, follow the [Javadoc Style Guide](contributing/JavadocStyleGuide.md).
* For new features, the feature should be mentioned in the [Release Notes](platforms/documentation/docs/src/docs/release/notes.md).

In most of the cases, the main cloud providers have guides to deploy FastAPI with them.

Istio installer is a modular, 'a-la-carte' installer for Istio. It is based on a
fork of the Istio helm templates, refactored to increase modularity and isolation.

Goals:

`tags` 매개변수를 *경로 작동* 및 `APIRouter`와 함께 사용하여 태그에 할당할 수 있습니다:

```Python hl_lines="21  26"
{!../../docs_src/metadata/tutorial004.py!}
```

/// info

태그에 대한 자세한 내용은 [경로 작동 구성](path-operation-configuration.md#tags){.internal-link target=_blank}에서 읽어보세요.

## Instalando `WebSockets`

Garanta que você criou um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, o ativou e instalou o `websockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## Cliente WebSockets

### Em produção

    As always, in FastAPI you can combine `def` and `async def` as needed.

    If you need a refresher about when to use which, check out the section _"In a hurry?"_ in the docs about [`async` and `await`](../async.md#in-a-hurry){.internal-link target=_blank}.

9. This *path operation function* is not returning dataclasses (although it could), but a list of dictionaries with internal data.
