Question

我试图让ngExpressEngine与JIT编译器（Angular 4.1.X）一起使用，但是有一个问题。为什么JIT需要元数据？

Angular版本：4.1.X
语言：TypeScript 2.2
操作系统：Mac OS X
平台：NodeJs

Error: No NgModule metadata found for 'MainModule'.

   at ServerResponse.render (/Users/matthias/Documents/private workspace/chaoslistapi/node_modules/express/lib/response.js:960:7)

这是我的服务器模块

import { NgModule } from '@angular/core'
import { FormsModule } from '@angular/forms'
import { RouterModule } from '@angular/router'

import { AppModule, AppComponent } from './app/app.module'
import { SharedModule } from './app/shared/shared.module'

import { BrowserModule, Meta } from '@angular/platform-browser'
import { ServerModule } from '@angular/platform-server'

export function getLRU() {
  return new Map()
}
export function getRequest() {
  return Zone.current.get('req') || {}
}
export function getResponse() {
  return Zone.current.get('res') || {}
}

@NgModule({
  bootstrap: [ AppComponent ],
  imports: [
    BrowserModule.withServerTransition({
      appId: 'chaoslist'
    }),
    ServerModule,

    FormsModule,
    RouterModule.forRoot([], { useHash: false }),

    SharedModule.forRoot(),
    AppModule
  ],
  providers: [
    { provide: 'isBrowser', useValue: false },
    { provide: 'isNode', useValue: true },

    { provide: 'req', useFactory: getRequest },
    { provide: 'res', useFactory: getResponse },

    { provide: 'LRU', useFactory: getLRU, deps: [] },

    Meta
  ]
})

export class MainModule {

}

我打电话给ngExpressEngine。我找到了一个JIT集成的提交，所以理论上应该这样做。这是一个新的错误还是我在这里做了一些明显的错误？

// Angular 2 Universal
import { ngExpressEngine } from '@nguniversal/express-engine';

// App
import { MainModule } from './node.module';
// Express View
    this.app.engine('html', ngExpressEngine({
      bootstrap: MainModule
    }));

angular-universal setup使用JIT-Compiler抛出“找不到元数据”-exception
