@Inject(REQUEST) not available at angular side

Current behavior

SSR does not provide the current host for DI.

Expected behavior

“request” should not be null in angular services.

constructor(private http: HttpClient,
              @Optional() @Inject(REQUEST) private request: any,
              @Inject(PLATFORM_ID) private platformId: Object) {
    if (isPlatformServer(this.platformId)) {
      console.log(this.request.get('host')); // host on the server
    } else {
      console.log(document.location.hostname); // host on the browser
    }
  }

What is the motivation / use case for changing the behavior?

Angular needs absolute urls at server side for api calls to the backend. See: https://angular.io/guide/universal#using-absolute-urls-for-server-requests

express-engine supports this as shown under “Request based Bootstrap”: https://github.com/angular/universal/blob/master/modules/express-engine/README.md

It seems that this is still problem (v.4.0.1), REQUEST is null in ng component on ssr.

My app.component.ts

import { Component, Inject, Optional, PLATFORM_ID } from '@angular/core';
import { Request } from 'express';
import { REQUEST } from '@nguniversal/express-engine/tokens';
import { isPlatformServer } from '@angular/common';

@Component({
  selector: 'workspace-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.styl'],
})
export class AppComponent {
  title = 'title';

  constructor(
    @Optional() @Inject(REQUEST) private request: Request,
    @Inject(PLATFORM_ID) private readonly platformId: any,
  ) {
    if (isPlatformServer(this.platformId)) {
      console.log('my request', this.request);
    }
  }
}

Providers for REQUEST and RESPONSE were removed in that commit https://github.com/nestjs/ng-universal/commit/b43e23fbc9031405937603a2f0ef4d9a82cd6d5d#diff-a721ebf1ae45ad7227e059567df31f08L39
