Vue-cli的图片和文件压缩

文件压缩

cnpm install --save-dev compression-webpack-plugin

module.exports = {

                    minRatio: 0.8, // 只有压缩率小于这个值的资源才会被处理
                    deleteOriginalAssets: false // 删除原文件
                })

原文 今天被问到了,只知道是插件,不知道什么插件,好尴尬 哈哈

最小化JS文件

config.optimization.minimize(true);

图片资源压缩

yarn add  image-webpack-loader

config.module
  .rule('images')
  .use('image-webpack-loader')
  .loader('image-webpack-loader')
  .options({
    bypassOnDebug: true
  })
  .end()
