[JavaScript知识库]vue.config.js configureWebpack 对象和函数两种使用方法

函数时：

``configureWebpack: (config) => {

let UglifyPlugin = require('uglifyjs-webpack-plugin');

if (process.env.NODE_ENV == 'production') {
  // 为生产环境修改配置
  config.mode = 'production'
  // 将每个依赖包打包成单独的js文件
  let optimization = {
    minimizer: [new UglifyPlugin({
        uglifyOptions: {
            warnings: false,
            compress: {
              drop_console: true, 
              drop_debugger: false,
              pure_funcs: ['console.log'] 
            }
        }
     })]
  }
  Object.assign(config, {
    optimization
  })
} else {
  // 为开发环境修改配置
  config.mode = 'development'

}
},

对象时：
configureWebpack: {
// provide the app’s title in webpack’s name field, so that
// it can be accessed in index.html to inject the correct title.
name: name,
resolve: {
alias: {
‘@’: resolve(‘src’),
‘@crud’: resolve(‘src/components/Crud’)
}
}
},
如果需要结合使用：
configureWebpack: (config) => {

config.name = name
config.resolve = {
  ...config.resolve,
  alias: {
    '@': resolve('src'),
    '@crud': resolve('src/components/Crud')
  }
}


//  引入uglifyjs-webpack-plugin
let UglifyPlugin = require('uglifyjs-webpack-plugin');

if (process.env.NODE_ENV == 'production') {
  // 为生产环境修改配置
  config.mode = 'production'
  // 将每个依赖包打包成单独的js文件
  let optimization = {
    minimizer: [new UglifyPlugin({
        uglifyOptions: {
            warnings: false,
            compress: {
              drop_console: true, 
              drop_debugger: false,
              pure_funcs: ['console.log'] 
            }
        }
     })]
  }
  Object.assign(config, {
    optimization
  })
} else {
  // 为开发环境修改配置
  config.mode = 'development'

}
},

具体使用参考这位小哥，写的非常nice~：
