## Install FastAPI

The first step is to install FastAPI.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then **install FastAPI**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

		}
	}
	return
}

func handleAndGetXdsConfigs(clientConfig *xdsstatus.ClientConfig) []*xdsstatus.ClientConfig_GenericXdsConfig {
	configs := make([]*xdsstatus.ClientConfig_GenericXdsConfig, 0)
	if clientConfig.GetGenericXdsConfigs() != nil {
		configs = clientConfig.GetGenericXdsConfigs()
		return configs
	}

   * java.util.Collection} specified in the {@link Map} interface.

  @Override
  Set<V> values();

  /**
   * Returns the inverse view of this bimap, which maps each of this bimap's values to its
   * associated key. The two bimaps are backed by the same data; any changes to one will appear in
   * the other.

This way, its schema will show up in the API docs user interface:

## Dataclasses in Nested Data Structures

You can also combine `dataclasses` with other type annotations to make nested data structures.

In some cases, you might still have to use Pydantic's version of `dataclasses`. For example, if you have errors with the automatically generated API documentation.

		}
		if port == 0 {
			port = 8021 // Default FTP port, since no port was given.
		}
	}

	// If no TLS certs were provided, server is running in TLS for S3 API
	// we automatically make FTP also run under TLS mode.
	if globalIsTLS && tlsPrivateKey == "" && tlsPublicCert == "" {
		tlsPrivateKey = getPrivateKeyFile()
		tlsPublicCert = getPublicCertFile()
	}
