用webpack优化前端性能是指优化webpack的输出结果,让打包的最终结果在浏览器运行快速高效。
压缩代码。删除多余的代码、注释、简化代码的写法等等方式。可以利用webpack的UglifyJsPlugin和ParallelUglifyPlugin来压缩JS文件, 利用cssnano(css-loader?minimize)来压缩css 利用CDN加速。在构建过程中,将引用的静态资源路径修改为CDN上对应的路径。可以利用webpack对于output参数和各loader的publicPath参数来修改资源路径 删除死代码(Tree Shaking)。将代码中永远不会走到的片段删除掉。可以通过在启动webpack时追加参数--optimize-minimize来实现 提取公共代码。
