用webpack发布一个vue插件包

本来以为很简单，结果配置了webpack之后，运行build就报错了，似乎不认识es6语法，于是先后安装了几个包：

　　@babel/core

　　@babel/preset-env

　　babel-loader

　　@babel/plugin-proposal-class-properties

进行了一些配置：

// babel
const presets = [
    [
      '@babel/env',
      {
        targets: '> 0.25%, not dead',
        useBuiltIns: 'usage',
      },
    ],
]

const plugins = [
    '@babel/plugin-proposal-class-properties'
]
  
module.exports = { 
    presets, 
    plugins 
}



// rules
rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: "babel-loader"
      }
]

终于顺利打包成功，下面就开始发布了
