vue2项目打包时去除注释

在vue.config.js文件添加以下配置

const UglifyJsPlugin = require('uglifyjs-webpack-plugin')

module.exports = {
  configureWebpack: {
    optimization: {
      minimize: true,
      minimizer: [
        new UglifyJsPlugin({
          uglifyOptions: {
            output: {
              comments: false
            }
          }
        })
      ]
    }
  }
}

注意，没有uglifyjs依赖请先下载

npm install uglifyjs-webpack-plugin --save-dev
