Current behavior

I created a new Angular 6 application that is using a Angular Slick Carousel Plugin: https://github.com/devmark/ngx-slick.

Currently the application works fine when I run ng serve -o and even when I host my dist/browser/* contents in an S3 Bucket.

When I try to use either @ng-toolkit/universa I get the following problem from npm run server (btw all I see in localhost:8080 is this -> {}):

Listening on: http://localhost:8080

Expected behavior

Application should compile as it does when I run ng serve

Minimal reproduction of the problem with instructions

To reproduce the error do the following:

• create a new Angular Application
• add @ng-toolkit/universal
• Follow instructions to add slick https://github.com/devmark/ngx-slick

app.module.ts

import { NgtUniversalModule } from '@ng-toolkit/universal';
import { CommonModule } from '@angular/common';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { LandingPageComponent } from './landing-page/landing-page.component';

import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import { MaterialModule } from './material';
import { HomePageComponent } from './home-page/home-page.component';
import { ToolbarComponent } from './home-page/toolbar/toolbar.component';

// Import your library
import { SlickModule } from 'ngx-slick';

@NgModule({
  declarations: [
    AppComponent,
    LandingPageComponent,
    HomePageComponent,
    ToolbarComponent
  ],
  imports:[
      CommonModule,
      NgtUniversalModule,
    AppRoutingModule,
    BrowserAnimationsModule,
    MaterialModule,
    SlickModule.forRoot()
  ],
  providers: [],
})
export class AppModule { }

I'm facing same issue. How to solve??

[vikash09]

I solved my problem using this.

   constructor(
        @Inject(PLATFORM_ID) private platformId: Object
    ) { }

isPlatformBrowser() {
        if (isPlatformBrowser(this.platformId)) {
            return true;
        }
        return false;
    }

please try with this condition <div *ngIf="isPlatformBrowser()">your code</div> Hope this will help you.
