Doesn't work with angular 5

[el-davo]

Hi, Ive tried this lib in angular 5 but couldnt seem to get it to work. I have a component template like so

<a class="card clickable" [routerLink]="[product.id]">
    <div class="card-img">
      <img [lazyLoad]="product.logoUrl">
    </div>
  <div class="card-block">
    <span class="card-media-title">{{product.name}}</span>
    <div class="product-version">{{product.version}}</div>
    <div class="product-release-date">{{product.releaseDate}}</div>
  </div>
</a>

and a component like so

import {Component, Input} from '@angular/core';
import {Product} from '../products.state';

@Component({
  selector: 'app-product-card',
  templateUrl: './product-card.component.html',
  styleUrls: ['./product-card.component.scss']
})
export class ProductCardComponent {

  @Input() product: Product;

  constructor() {
  }

}

And my module

import {NgModule} from '@angular/core';
import {CommonModule} from '@angular/common';
import {LazyLoadImageModule} from 'ng-lazyload-image';
import {ProductsComponent} from './products.component';
import {ProductsEpic} from './products.epic';
import {ProductsListComponent} from './products-list/products-list.component';
import {ProductCardComponent} from './product-card/product-card.component';
import {ProductsService} from './products.service';
import {ProductsActions} from './products.actions';
import {ProductsEmptyComponent} from './products-empty/products-empty.component';
import {CoreModule} from '../core/core.module';
import {BannerComponent} from './banner/banner.component';
import {RouterModule} from '@angular/router';

@NgModule({
  imports: [
    CommonModule,
    RouterModule,
    CoreModule,
    LazyLoadImageModule
  ],
  declarations: [
    ProductsComponent,
    ProductsListComponent,
    ProductCardComponent,
    ProductsEmptyComponent,
    BannerComponent
  ],
  providers: [
    ProductsService,
    ProductsEpic,
    ProductsActions
  ]
})
export class ProductsModule {
}

The image simply never shows up. I also get this warning message in the console

Not sure what i'm doing wrong. Any help appreciated

Hi @el-davo,

Thanks for the report. Are you using any server rendering? Or precompile your app? Or are you running the app in develop mode?

[el-davo]

Hi. Nope am not doing server side rendering. Yep currently in dev mode using the angular-cli

What browser are you using? I just created a new angular app with the cli (Angular 5) and was not able to reproduce this. I did the following changes:

I also created a plnkr (https://embed.plnkr.co/rr046QU9YYWALdX7Xzf6/) but could not reproduce the error. Do you think you could create a small git repo or a plnkr to reproduce the error?

My apologies. I looked closer into my issue and it turned out I had this piece of css which seemed to be disabling all scroll events in the browser

html, body {
  overflow-x: hidden;
}

To get around this I added this custom scroll event like so

import {Component, Input} from '@angular/core';
import {Product} from '../products.state';
import {Observable} from 'rxjs/Observable';

@Component({
  selector: 'app-product-card',
  templateUrl: './product-card.component.html',
  styleUrls: ['./product-card.component.scss']
})
export class ProductCardComponent {

  @Input() product: Product;
  scrollObservable = Observable.fromEvent(document.body, 'scroll');

  constructor() {
  }

}

and in my template like so

<a class="card clickable" [routerLink]="[product.id]">
  <div class="card-img">
    <img [lazyLoad]="product.logoUrl" [scrollObservable]="scrollObservable">
  </div>
  <div class="card-block">
    <span class="card-media-title">{{product.name}}</span>
    <div class="product-version">{{product.version}}</div>
    <div class="product-release-date">{{product.releaseDate}}</div>
  </div>
</a>

Now it works perfectly in angular 5
