angular - 使用 uglifyjs webpack 插件修改属性会导致 Angular 应用程序中出现 Uncaught ReferenceError

Question

我有一个托管 Angular 6 应用程序的 .net Core 2.1 MVC 应用程序。我正在使用 webpack 4 来捆绑它。我想丑化我的代码以获得优化的好处，并在部署时尽可能地保护它。当我尝试修改属性名称时，我的 Angular 应用程序停止工作，并且出现错误：“未捕获的 ReferenceError：vendor_8b8ec7e9d2171cd0b5b6”未定义。如果我在 mangle 属性中将“properties”参数从 true 设置为 false，则一切正常但是属性和函数名称在丑陋的代码中。我真的希望它们被破坏。

请帮忙。
