这是一个创建于 2498 天前的主题，其中的信息可能已经有所发展或是发生改变。
最初用 vue init webpack-simple 创建了个项目， 写了一些东西，执行 npm run build 后打出了 800+kb 大小的 build.js， 不知道是什么原因它有这么大的体积，请高手指点下改进方式,谢谢了：
以下是我的配置: <<package.json>>

<<index.html>> 引入一些 cdn 和本地资源， 加起来目测 100kb 左右
<<main.js>> import Vue from 'vue' import App from './App.vue' import Modal from 'iview/src/components/modal'; import 'iview/dist/styles/iview.css' Vue.use(Modal) new Vue({ el: '#app', render: h => h(App) })

用 vue init webpack myproject 默认打包很小的, webpack-simple 不清楚

看你用的库有没有帮你处理按需引入，或者说有没有相关的说明文档。一般直接从模块名引入都是打包了整个组件库。

去掉 Sourcemap 会小很多
