webpack打包插件

const path = require(&＃8216;path&＃8217;); //引入node的path模块
const webpack = require(&＃8216;webpack&＃8217;); //引入的webpack,运用lodash
const HtmlWebpackPlugin = require(&＃8216;html-webpack-plugin&＃8217;) //将html打包
const ExtractTextPlugin = require(&＃8216;extract-text-webpack-plugin&＃8217;) //打包的css拆分,将一部分抽离出来
const CopyWebpackPlugin = require(&＃8216;copy-webpack-plugin&＃8217;)
// console.log(path.resolve(__dirname,&＃8217;dist&＃8217;)); //物理地址拼接

优化打包速率
cOnstUglifyJsPlugin= require(&＃8216;uglifyjs-webpack-plugin&＃8217;);
紧缩代码，这里运用的是uglifyjs-webpack-plugin，同样在webpack.config.js的plugin内里增加

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
}
})
]
