Then you can serve that with the command `serve`:

<div class="termy">

```console
// Use the command "serve" after running "build-all"
$ python ./scripts/docs.py serve

Warning: this is a very simple server. For development, use mkdocs serve instead.
This is here only to preview a site with translations already built.
Make sure you run the build-all command first.
Serving at: http://127.0.0.1:8008
```

在新的 Terminal 里，用以下命令确认 CLI 是否正确安装：

<div class="termy">

```console
$ deta --help

Deta command line interface for managing deta micros.
Complete documentation available at https://docs.deta.sh

Usage:
  deta [flags]
  deta [command]

Available Commands:
  auth        Change auth settings for a deta micro

...
```

</div>

# Run a Server Manually

## Use the `fastapi run` Command

In short, use `fastapi run` to serve your FastAPI application:

<div class="termy">

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

Se stai sviluppando un'app <abbr title="Command Line Interface (interfaccia della riga di comando)">CLI</abbr> da usare nel terminale invece che una web API, ti consigliamo <a href="https://typer.tiangolo.com/" class="external-link" target="_blank">**Typer**</a>.

## Аннотация типа или `Depends`

Обратите внимание, что в приведенном выше коде мы два раза пишем `CommonQueryParams`:

=== "Python 3.6+ без Annotated"

    !!! tip "Подсказка"
        Рекомендуется использовать версию с `Annotated` если возможно.

    ```Python
    commons: CommonQueryParams = Depends(CommonQueryParams)
    ```

## 💯

Alternatively, if you don't have a way to provide a command line option like `--root-path` or equivalent, you can set the `root_path` parameter when creating your FastAPI app:

```Python hl_lines="3"
{!../../../docs_src/behind_a_proxy/tutorial002.py!}
```

Passing the `root_path` to `FastAPI` would be the equivalent of passing the `--root-path` command line option to Uvicorn or Hypercorn.

#### Generate Client Code

To generate the client code you can use the command line application `openapi-ts` that would now be installed.

Because it is installed in the local project, you probably wouldn't be able to call that command directly, but you would put it on your `package.json` file.

It could look like this:

```JSON  hl_lines="7"
{
  "name": "frontend-app",

## **Typer**，命令行中的 FastAPI

如果你正在开发一个在终端中运行的<abbr title="Command Line Interface">命令行</abbr>应用而不是 web API，不妨试下 <a href="https://typer.tiangolo.com/" class="external-link" target="_blank">**Typer**</a>。

**Typer** 是 FastAPI 的小同胞。它想要成为**命令行中的 FastAPI**。 ⌨️ 🚀
