網(wǎng)上找了很多vue-cli 3.x的配置，很多已經(jīng)不適用了，把采坑的經(jīng)歷記錄下來，供參考。

一、使用 uglifyjs-webpack-plugin 插件

配置如下:

// vue.config.js
const UglifyJsPlugin = require("uglifyjs-webpack-plugin")
module.exports = {
    configureWebpack: {
        optimization: {
          minimizer: [
            new UglifyJsPlugin({
              uglifyOptions: {
                compress: {
                  warnings: false,
                  drop_console: true,//console
                  drop_debugger: false,
                  pure_funcs: ["console.log"]//移除console
                }
              }
            })
          ]
        }
  },
}

沒成功報(bào)錯(cuò)如下

$ vue-cli-service build

?  Building for production...

 ERROR  Failed to compile with 5 errors                                                                                                                                                                                     11:19:57 AM

 error

 error

 error

Unexpected token: punc ?(? [static/js/exception_500.94c7c527.js:1,283]

 ERROR  Build failed with errors.
error Command failed with exit code 1.

二、配置optimization.minimizer

參考 vuecli3+webpack4優(yōu)化實(shí)踐（刪除console.log和配置dllPlugin）

// vue.config.js
module.exports = {
    chainWebpack: (config) => {
        if (process.env.NODE_ENV === "production") {
          config.optimization.minimizer[0].options.terserOptions.compress.warnings = false
          config.optimization.minimizer[0].options.terserOptions.compress.drop_console = true
          config.optimization.minimizer[0].options.terserOptions.compress.drop_debugger = true
          config.optimization.minimizer[0].options.terserOptions.compress.pure_funcs = ["console.log"]
        }
    }
}

最終還是沒有成功，報(bào)錯(cuò)如下：

$ vue-cli-service build

?  Building for production... ERROR  TypeError: Cannot read property "options" of undefined
TypeError: Cannot read property "options" of undefined

三、使用babel-plugin-transform-remove-console插件

參考 https://forum.vuejs.org/t/rem...

# 安裝依賴庫
$ npm install babel-plugin-transform-remove-console --save-dev
# or
$  yarn add babel-plugin-transform-remove-console --dev

【babel.config.js】配置如下

const plugins = ["@vue/babel-plugin-transform-vue-jsx"]
// 生產(chǎn)環(huán)境移除console
if(process.env.NODE_ENV === "production") {
  plugins.push("transform-remove-console")
}
module.exports = {
  plugins: plugins,
  presets: [
    [
      "@vue/app", {
        modules: false,
        targets: {
          browsers: ["> 1%", "last 2 versions", "not ie <= 8", "Android >= 4", "iOS >= 8"]
        },
        useBuiltIns: "entry",
      }
    ]
  ]
}
