plugins: [
        // http://vuejs.github.io/vue-loader/en/workflow/production.html
        new webpack.DefinePlugin({
            'process.env': env
        }),
        new UglifyJsPlugin({
            uglifyOptions: {
                // include: //src/,
                compress: {
                    warnings: false,
                    drop_debugger: true, //自动删除debugger
                    drop_console: true //自动删除console.log
                }
            },
            sourceMap: config.build.productionSourceMap,
            parallel: true
        })
]

  plugins.push('transform-remove-console');
}
module.exports = {
  presets: [
    [
      '@vue/app',
      {
        polyfills: ['es6.promise', 'es6.symbol']
      }
    ]
  ],
