为什么我的角度服务时间很慢？

Question

我公司的产品是带有Angular的Web应用程序。当我使用CMD启动ng服务时，处理速度非常慢。我下载了一个名为ng-alain的开源管理模板。 https://github.com/cipchk/ng-alain由 ng提供服务，速度非常快，ng-alain的速度至少比我快7倍。 然后我使用ng-eject命令导出webpack-config.js，发现我的配置中的exclude包含了许多第三方依赖包，例如JQuery，Bootstrap等。但是ng-alain的配置只包含样式。减。 我比较它们之间的angular-cli.json，如下所示。 矿：

我想知道ng-alain中在哪里添加了JQuery，Bootstrap等第三种语法？为什么ng-alain可以比我的快很多？
