Angular编译缓慢
我在Symfony-PHP中有一个API，我用postman对其进行了测试，它的工作原理就像是一种魅力。但是，当我执行ng serve --aot --optimization时，应用程序开始构建，并且compiled successfully.的消息花费了超过一分钟的时间。当我需要对html组件（如字母）进行更改时，它将重新编译整个项目，并且花费这么小的更改时间太长。
--watch参数默认设置为true，可以。我不知道是否有人知道为什么编译这么慢。

省略--optimization。这样，基于变更的构建将花费更少的时间。也尝试不使用--aot。首次构建总是需要一些时间。但是随后增量构建仅需几秒钟。
