webpack打包插件

const path = require(‘path’); //引入node的path模块const webpack = require(‘webpack’); //引入的webpack,使用lodashconst HtmlWebpackPlugin = require(‘html-webpack-plugin’) //将html打包const ExtractTextPlugin = require(’extract-text-webpack-plugin’) //打包的css拆分,将一部分抽离出来 const CopyWebpackPlugin = require(‘copy-webpack-plugin’)// console.log(path.resolve(__dirname,‘dist’)); //物理地址拼接优化打包速度constUglifyJsPlugin= require(‘uglifyjs-webpack-plugin’);压缩代码，这里使用的是uglifyjs-webpack-plugin，同样在webpack.config.js的plugin里面添加constUglifyJsPlugin= require(‘uglifyjs-webpack-plugin’);plugins:[ new UglifyJsPlugin({ uglifyOptions: { output: { beautify: false, comments: false, }, compress: { warnings: false, drop_debugger: true, drop_console: true, pure_funcs: [‘console.log’, ‘(e = console).log’ ] }, sourceMap: false } })]
