vue中使用markdown富文本，并在html页面中展示

想给自己的后台增加一个markdown编辑器，下面记录下引用的步骤

引入组件mavon-editor

官网地址：https://github.com/hinesboy/mavonEditor

// 插件下载
npm install mavon-editor -S
// 引入组件
<script>
  import { mavonEditor } from 'mavon-editor'
  import 'mavon-editor/dist/css/index.css'
</script>

comoponents: {
    mavonEditor
}

//html引入
<div >
  <mavon-editor  v-model="value"></mavon-editor>
</div>

效果展示：

前台展示

后台录入markdowN语法后，获取文章，此时数据如下，是markdown语法格式。在前台展示需要利用marked插件和highlight.js处理

marked将markdown语法渲染成html语法

npm install marked -S

<script>
    import marked from 'marked'
    var markdowncontent = "console.log('hello.word')"
    this.content = marked(markdowncontent)
</script>

代码高亮

npm install highlight.js
<script>

import '@/assets/css/markdown/dark.css' //引入代码高亮的css
import hljs from 'highlight.js'

//封装成一个指令
Vue.directive('highlight', (el) => {
    let blocks = el.querySelectorAll('pre code')
    blocks.forEach((block) => {
        hljs.highlightBlock(block)
    })
})

</script>

<div v-highlight v-html="content"></div>

mardown文章样式

<div class="passage">
    <div class="content"></div>
</div>

<style>
