我正在尝试使用Angular2的自定义渲染器.
我已经设置了一个简单的示例项目,其中包含AppComponent我想在Node.js上运行的最小Angular2应用程序().我已经实现了一个自定义的DomAdapter和一个自定义渲染器(只是一个应该登录到控制台的虚拟),然后我尝试在一些自定义引导代码中连接所有内容.
目前,我遇到以下错误消息:
Error: No precompiled component AppComponent found

有人可以解释这意味着什么,缺少什么？
更新:
正如Tobias Bosch指出的那样,COMPILER_PROVIDERS失踪了.但是,添加它们后,我得到另一个错误:
Error: DI Exception

at …我有个问题:
将ElementRef.nativeElement用于读取属性值(例如'scrollHeight')计为DOM交互并因此打破Angular Universal？
ElementRef似乎是从元素中读取属性的唯一方法:https://stackoverflow.com/a/38037240/5565132
例:
HTML:
<div #test1></div>
TS:
@ViewChild('test1') test1: ElementRef;
ngOnInit() {
console.log(this.test1.nativeElement.scrollHeight);
}
