The command `uvicorn main:app` refers to:

* `main`: the file `main.py` (the Python "module").
* `app`: the object created inside of `main.py` with the line `app = FastAPI()`.

It is equivalent to:

```Python
from main import app
```

# FastAPI CLI { #fastapi-cli }

**FastAPI <abbr title="command line interface - 命令列介面">CLI</abbr>** 是一個命令列程式，你可以用它來啟動你的 FastAPI 應用程式、管理你的 FastAPI 專案，等等。

當你安裝 FastAPI（例如使用 `pip install "fastapi[standard]"`）時，會附帶一個可以在終端機執行的命令列程式。

要在開發時運行你的 FastAPI 應用程式，你可以使用 `fastapi dev` 指令：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

The [mc sql](https://docs.min.io/community/minio-object-store/reference/minio-mc/mc-sql.html) command can be used for executing queries using the command line.
