OpenAPI中所包含的模型里有相同的信息可以用于 **生成客户端代码**。

### 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"
