Angular 8 CLI : Disable differential loading in development serve

Question

自从升级到 Angular 8 以来，我们的项目中默认启用了差异加载，并导致 ES5 和 ES2015 的 polyfill。虽然我很欢迎这个改动，但是有没有什么方法可以强制在开发模式下使用 ES2015 模式呢？我试图从初始和增量构建时间中减少任何一秒，分别超过 40/8 秒。

Answer 1

ES5 默认禁用用于开发 ng serve .

In Angular CLI version 8 and higher, differential loading is enabled by default for the ng build command. The ng serve, ng test, and ng e2e commands, however, generate a single ES2015 build which cannot run in older browsers that don't support the modules, such as IE 11.

我相信它也被禁用 ng build --watch ，但如果这是有意的行为，我没有找到任何引用。
