Demo Container V2

# 复杂示例

此处提供了两种复杂场景的示例，Demo Container V2 都能良好的支持，具体效果如下所示：

# TodoMVC 示例

本例子取自 Vue 官方文档示例中较为复杂的 TodoMVC，其展示效果 点此查看

拷贝官方代码将其改造成 template 的写法后，通过以下语法引用

::: demo `TodoMVC` 是 `Vue` 官方文档中提供的示例，其涵盖了 `data、watch、computed、methods、directives` 等较多 `API` 调用
```html
// Omit TodoMVC related code...

其渲染结果如下所示

# 结合组件库示例

作为一个 组件示例插件，其使用场景大多是在开发组件库时，用作组件库的文档示例构建，在此将演示基于 AntDeisgnVue 组件库的文档示例编写

首先我们在 Vuepress 中 引入 AntDesignVue 组件库：

yarn add ant-design-vue

然后编辑 .vuepress/enhanceApp.js 文件（如不存在则创建）：

import Antd from 'ant-design-vue'
import 'ant-design-vue/dist/antd.css'
export default ({
  Vue
}) => {
  Vue.use(Antd)
}

到这里就完成组件库的引入，现在可以找一个 Markdown 文件键入以下代码

::: demo  `AntDesignVue` xxx组件示例，**请注意xxx**
```html
<template>
	<a-button type="primary">Primary</a-button>
	<a-button type="danger">Danger</a-button>
	<a-config-provider :auto-insert-space-in-button="false">
		<a-button type="primary">按钮</a-button>
	</a-config-provider>
</template>
` ``
:::

渲染结果如下所示

AntDesignVue xxx组件示例，请注意xxx

<template>
	<a-button type="primary">Primary</a-button>
	<a-button type="danger">Danger</a-button>
	<a-config-provider :auto-insert-space-in-button="false">
		<a-button type="primary">按钮</a-button>
	</a-config-provider>
</template>
