vue-cli3中使用markdown并在markdown中执行vue代码

一、安装依赖

yarn add vue-markdown-loader markdown-it markdown-it-container

  yarn add highlight.js

二、在vue.config.js中引入插件并配置webpack

const markdownRender = require('markdown-it')()
module.exports = {
  chainWebpack: (config) => {
    /*  */
    config.module
      .rule('md')
      .test(/.md$/)
      .use('vue-loader')
      .loader('vue-loader')
      .end()
      .use('vue-markdown-loader')
      .loader('vue-markdown-loader/lib/markdown-compiler')
      .options({
        wrapper: 'article',
        wrapperName: '123',
        raw: true,
        preventExtract: true,
        use: [
          [
            require('markdown-it-container'),
            'demo',
            {
              validate: function (params) {
                return params.trim().match(/^demos+(.*)$/)
              },

              render: function (tokens, idx) {
                if (tokens[idx].nesting === 1) {
                  // 1.获取第一行的内容使用markdown渲染html作为组件的描述
                  let demoInfo = tokens[idx].info.trim().match(/^demos+(.*)$/)
                  let description =
                    demoInfo && demoInfo.length > 1 ? demoInfo[1] : ''
                  let descriptionHTML = description
                    ? markdownRender.render(description)
                    : ''
                  // 2.获取代码块内的html和js代码
                  let content = tokens[idx + 1].content
                  // 3.使用自定义开发组件【DemoBlock】来包裹内容并且渲染成案例和代码示例
                  return `<demo-block>
          <div class="source" slot="source">${content}</div>
          ${descriptionHTML}
          <div class="highlight" slot="highlight">`
                } else {
                  return '</div></demo-block>
'
                }
              },
            },
          ],
        ],
      })
  },
}

三、在assets目录下新建github-markdown.css文件（这个css文件是markdown的样式文件，我从githib上下载到本地来的）

article .octicon {
    display: inline-block;
    fill: currentColor;
    vertical-align: text-bottom;
}

article .anchor {
    float: left;
    line-height: 1;
    margin-left: -20px;
    padding-right: 4px;
}

article .anchor:focus {
    outline: none;
}

四、新建markdown-block.vue

<template>
  <div class="demo-block">
    <div class="demo-block-source">
      <slot name="source"></slot>
      <span
        class="demo-block-code-icon"
        v-if="!$slots.default"
        @click="showCode = !showCode"
        ><img
          alt="expand code"
          src="https://gw.alipayobjects.com/zos/rmsportal/wSAkBuJFbdxsosKKpqyq.svg"
          class="code-expand-icon-show"
      /></span>
    </div>
    <div class="demo-block-meta" v-if="$slots.default">
      <slot></slot>
      <span
        v-if="$slots.default"
        class="demo-block-code-icon"
        @click="showCode = !showCode"
        ><img
          alt="expand code"
          src="https://gw.alipayobjects.com/zos/rmsportal/wSAkBuJFbdxsosKKpqyq.svg"
          class="code-expand-icon-show"
      /></span>
    </div>
    <div class="demo-block-code" v-show="showCode">
      <slot name="highlight"></slot>
    </div>
  </div>
</template>
<script type="text/babel">
import 'highlight.js/styles/color-brewer.css';  
export default {
  data() {
    return {
      showCode: false,
    }
  },
}
</script>
<style scoped>
@import '../../assets/css/github-markdown.css';
.demo-block {
  border: 1px solid #ebedf0;
  border-radius: 2px;
  display: inline-block;
   100%;
  position: relative;
  margin: 0 0 16px;
  -webkit-transition: all 0.2s;
  transition: all 0.2s;
  border-radius: 2px;
}
.demo-block p {
  padding: 0;
  margin: 0;
}
.demo-block .demo-block-code-icon {
  position: absolute;
  right: 16px;
  bottom: 14px;
  cursor: pointer;
   18px;
  height: 18px;
  line-height: 18px;
  text-align: center;
}
.demo-block .demo-block-code-icon img {
  -webkit-transition: all 0.4s;

  -webkit-user-select: none;
  -moz-user-select: none;

  margin: 0;
  max- 100%;
   100%;
  vertical-align: baseline;
  -webkit-box-shadow: none;
  box-shadow: none;
}
.demo-block .demo-block-source {
  border-bottom: 1px solid #ebedf0;
  padding: 20px 24px 20px;
  color: #444;
  position: relative;
  margin-bottom: -1px;
}

  border-bottom: 1px dashed #ebedf0;
  margin-bottom: -1px;
}
.demo-block .demo-block-meta code {

  background-color: #e6effb;
  margin: 0 4px;
  display: inline-block;
  padding: 3px 7px;
  border-radius: 3px;
  height: 18px;
  line-height: 18px;
  font-family: Menlo, Monaco, Consolas, Courier, monospace;
  font-size: 14px;
}
.demo-block .demo-block-code {

.demo-block .demo-block-code pre {

  padding: 0;
}
.sh-checkbox {

  font-weight: 500;
  font-size: 14px;
  position: relative;
  cursor: pointer;
  display: inline-block;
  white-space: nowrap;
  user-select: none;
}
</style>

五、在main.js中注册组件

import DemoBlock from '@/components/public/markdown-block.vue'
Vue.component('demo-block', DemoBlock)

　　

六、在根目录下新建 ui/docs/tab-search.md 文件

## Button 按钮

常用的操作按钮

### 基础用法 

按钮的基础用法

:::demo 通过`type`、`width`属性设置不同类型的按钮

```html
<template>
    <div>
        <el-button>默认按钮</el-button>
        <el-button type="success">成功按钮</el-button>
        <el-button type="warning">警告按钮</el-button>
        <el-button type="danger">危险按钮</el-button>
    </div>
    <div>
        <el-button width="100px">默认按钮</el-button>
        <el-button type="success" width="100px">成功按钮</el-button>
        <el-button type="warning" width="100px">警告按钮</el-button>
        <el-button type="danger" width="100px">危险按钮</el-button>
    </div>
</template>
\```  (去除这个斜杠)

:::

### Attributes
| 参数      | 说明    | 类型      | 可选值       | 默认值   |
|--------|--------   |---------- |-------------  |-------- |
| type   | 类型      | string    |   success / warning / danger / |—    |
| name   | name属性  | string    | — | —   |
| id     | id属性    | string    | — | —   |
| width  | 按钮宽度   | string    | — | 100%   |

　　

七、配置路由

      {
        path: '/search',
        name: 'search',
        meta: {
          title: '搜索',
          icon: 'home1',
          keepAlive: true,
        },
        component: () => import('@/ui/docs/tab-search.md'),
      },
