Vue-Webpack-Pc && 移动端

谁能想到这是一个广告！！

地址 github.com/jason-xiewe…

配置详情请看 webpack config.js

Vue + Vuex + vue-router + ElementUI + Axios

命令

• ① npm install 安装依赖包

• ② npm run serve 开启本地开发模式 localhost: 8080

• ③ npm run build 生产打包

• ⑤ npm run analyzer 进行包分析 localhost: 8888

优化打包速度 *

开启多线程打包 第三方组件单独打包 图片处理 *

多浏览器方案适配 ** 整合 polyfill

移动端方案适配 ** lib-flexible 库
