打包速度优化
Webpack 默认提供的 UglifyJS 插件，由于采用单线程压缩，速度颇慢 ；推荐采用 webpack-parallel-uglify-plugin 插件，其做法如下，
new webpack.optimize.UglifyJsPlugin({ ?compress: { ???warnings: false ?}, ?sourceMap: true})替换如上自带的 UglifyJsPlugin 写法为如下配置即可：
var ParallelUglifyPlugin = require(‘webpack-parallel-uglify-plugin‘);new ParallelUglifyPlugin({ ?cacheDir: ‘.cache/‘, ?uglifyJS:{ ???output: { ?????comments: false ???}, ???compress: { ?????warnings: false ???} ?}})去掉正式环境的console.log
在压缩插件里过滤掉即可，加后的代码如下：
???new ParallelUglifyPlugin({ ?????cacheDir: ‘.cache/‘, ?????uglifyJS:{ ???????output: { ?????????comments: false ???????}, ???????compress: { ?????????warnings: false, ?????????drop_console: true, ?????????pure_funcs: [‘console.log‘] ???????} ?????} ???})webpack打包速度优化
