在vue项目中使用prismjs

什么是prismjs

prismjs是一款代码高亮美化插件，在一些技术博客类的网站中需要展示代码时，可以使用它类似与markdown的代码块，
官网链接：https://prismjs.com/index.html

怎么使用

1、安装插件

//安装prismjs 插件
npm install prismjs -S

//安装prismjs的编译器插件
npm install babel-plugin-prismjs -D

2、配置插件

在项目下找到babel.config.js
在module.exports中的plugins追加以下配置，如果原本没有plugins可以手动添加

 module.exports = {
  plugins: [
    ["prismjs", {
      "languages": ["javascript", "css", "markup"],
      "plugins": ["line-numbers"], //配置显示行号插件
      "theme": "okaidia", //主体名称
      "css": true
    }]
  ]
}

3、在项目中引入模块

import Prism from "prismjs";

在钩子函数mounted中添加

Prism.highlightAll()

4、在需要美化的代码块中添加class

注意这里的html结构是pre包裹着code

类名的含义

line-numbers显示行号
language-xxx或lang-xxx选择编程语言，如：language-js

<pre>
    <code class="language-js line-numbers" >
        let msg = "这是一段代码演示"
        console.log(msg)
    </code>
</pre>

效果如下：

类名对照表

横杠-前的是语言，横杠后的是对应类名：
如：JavaScript - javascript, js
对应的类名是：language-jsorlanguage-javascript,以此类推
