## Зависимости

FastAPI стоит на плечах гигантов:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> для части связанной с вебом.
* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> для части связанной с данными.

## Установка

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

### 生成一个TypeScript 客户端

现在我们有了带有模型的应用，我们可以为前端生成客户端代码。

#### 安装 `openapi-ts`

您可以使用以下工具在前端代码中安装 `openapi-ts`:

<div class="termy">

```console
$ npm install @hey-api/openapi-ts --save-dev

---> 100%
```

</div>

#### 生成客户端代码

要生成客户端代码，您可以使用现在将要安装的命令行应用程序 `openapi-ts`。

因为它安装在本地项目中，所以您可能无法直接使用此命令，但您可以将其放在 `package.json` 文件中。

它可能看起来是这样的:

```JSON  hl_lines="7"
{

{!../../docs_src/query_params_str_validations/tutorial006c.py!}
```

/// tip

Pydantic 是 FastAPI 中所有数据验证和序列化的核心，当你在没有设默认值的情况下使用 `Optional` 或 `Union[Something, None]` 时，它具有特殊行为，你可以在 Pydantic 文档中阅读有关<a href="https://docs.pydantic.dev/latest/concepts/models/#required-optional-fields" class="external-link" target="_blank">必需可选字段</a>的更多信息。

///

### 使用Pydantic中的`Required`代替省略号(`...`)

如果你觉得使用 `...` 不舒服，你也可以从 Pydantic 导入并使用 `Required`：
