【Web前端问题】webpack打包的vendor文件很大，并且代码没有混淆！

项目使用的是vue+webpack
UI组件库有element UI 和 iview 现在打包出来的文件非常之大

查看打包完成的vendor.js
代码并没有被混淆
图片描述

报错是因为引入了 "vue-particles": "1.0.9",
.babelrc文件已经按网上的方法修改了，还是报错！但是代码可以运行

/`{
"presets": [

["es2015", { "modules": false }],
"stage-2"

],
"plugins": ["transform-runtime"],
"comments": false,
"env": {

"test": {
  "plugins": [ "istanbul" ]
}

}
}`/

访问的速度不理想

急需优化！请大牛提供部分解决方法或优化思路！！！

回答：

使用Webpack的UglifyJsPlugin插件，压缩代码、删除console.log等调试语句、删除单行/多行/文档注释、删除sourceMap、copyright等。
配置类似于：
new webpack.optimize.UglifyJsPlugin({

sourceMap: false,
show_copyright: false,
comments: false,
compress: {
    warnings: false
    drop_debugger: true,
    drop_console: true
}

})

具体看官方文档

这样一般可以把文件减少60%以上，然后服务器端开启gzip压缩，可以把请求文件大小再减少70%以上。

图片点击放大的插件打包错误，我也是用了这个插件错误，楼主解决了吗？还是换了别人的插件，可以介绍下么？
