我有一个API in Symfony-PHP，我用它来测试postman它就像一个魅力。但当我这样做时ng serve --aot --optimization应用程序开始构建并且消息compiled successfully.需要一分多钟。
当我需要更改html对于诸如信件之类的组件，它会重新编译整个项目，并且对于如此小的更改来说花费的时间太长。
The --watch参数设置为true默认情况下，这是可以的。不知道有没有人知道为什么编译这么慢。

忽略--optimization。那么基于变革的构建将花费更少的时间。也尝试不使用--aot。第一次构建总是需要一些时间。但增量构建只需要几秒钟。
