在vue项目中使用prismjs（网页代码高亮插件）
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：
