Vue 实现CLI 3.0 + momentjs + lodash打包时优化

yarn add momentjs
yarn add webpack-bundle-analyzer lodash-webpack-plugin --dev //优化要用到的插件

var webpack = require('webpack') //引入webpack库
var BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin //引入webpack-bundle-analyzer

module.exports = {
  chainWebpack: config => {
    config.plugin('ignore')
      .use(new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/));//忽略/moment/locale下的所有文件
    config.plugin('analyzer')
      .use(new BundleAnalyzerPlugin())//使用webpack-bundle-analyzer 生成报表
    config.plugin("loadshReplace")
     .use(new LodashModuleReplacementPlugin());//优化lodash
  }
}
