當你安裝 FastAPI（例如使用 `pip install "fastapi[standard]"`），它會包含一個叫做 `fastapi-cli` 的套件，這個套件提供了 `fastapi` 命令。

要運行你的 FastAPI 應用程式來進行開發，你可以使用 `fastapi dev` 命令：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

	[ ${first_time} -eq 0 ] && upload_objects
	[ ${first_time} -ne 0 ] && sleep 120

	if ! ps -p $pid1 1>&2 >/dev/null; then
		echo "minio server 1 is not running" && fail
	fi

	if ! ps -p $pid2 1>&2 >/dev/null; then
		echo "minio server 2 is not running" && fail
	fi

	if ! ps -p $pid3 1>&2 >/dev/null; then
		echo "minio server 3 is not running" && fail
	fi

	if ! pkill minio; then
		fail
	fi

	sleep 1

## Tente você mesmo

Se seu arquivo for nomeado `main.py`, execute sua aplicação com:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

		exit 1
	fi

	(cd "${MC_BUILD_DIR}" && go build -o "${WORK_DIR}/mc")

	# remove mc source.
	purge "${MC_BUILD_DIR}"

	shred -n 1 -s 1M - 1>"$FILE_1_MB" 2>/dev/null
	shred -n 1 -s 65M - 1>"$FILE_65_MB" 2>/dev/null

	## version is purposefully set to '3' for minio to migrate configuration file

					return ObjectLocked{}
				}

				if !ret.RetainUntilDate.Before(t) {
					return ObjectLocked{}
				}
				return nil
			}
			// https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lock-overview.html#object-lock-retention-modes
			// If you try to delete objects protected by governance mode and have s3:BypassGovernanceRetention, the operation will succeed.

```

This will generate a TypeScript SDK in `./src/client`.

You can learn how to <a href="https://heyapi.dev/openapi-ts/get-started" class="external-link" target="_blank">install `@hey-api/openapi-ts`</a> and read about the <a href="https://heyapi.dev/openapi-ts/output" class="external-link" target="_blank">generated output</a> on their website.

// It returns empty configuration if its not set.

<summary>About the command <code>fastapi dev main.py</code>...</summary>

The command `fastapi dev` reads your `main.py` file, detects the **FastAPI** app in it, and starts a server using <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>.

By default, `fastapi dev` will start with auto-reload enabled for local development.
