ngx-toastr, Toast not showing in Angular 7

Question

I'm currently developing a web app using Angular 7. I wanted to include ngx-toastr to send notifications to users but it isn't working as expected. When I trigger a toast nothing happens, except for a box in the size of a toast is appearing in bottom right corner but only when hovered over by the coursor. Following an example of how I trigger the toastr function. Test is invoked by the click of a button.

import {ToastrService} from 'ngx-toastr';
@Component({
  selector: 'app-action-controls',
  templateUrl: './action-controls.component.html',
  styleUrls: ['./action-controls.component.scss']
})
export class Notification implements OnInit {
  test(){   
          this.toast.success("I'm a toast!", "Success!");
  }
 constructor(private toast: ToastrService) { }
}

I includet the library css files in the angular.json file in my project like this:

     ...        
     "styles": [
        "src/styles.scss",
        "node_modules/bootstrap/scss/bootstrap.scss",
        "node_modules/ngx-toastr/toastr.css"
      ],
      ...

And like this in my app.module.ts file:

...
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import {ToastrModule} from 'ngx-toastr';
...
  imports: [
    ...
    BrowserAnimationsModule,
    ToastrModule.forRoot({
      timeOut: 1000,
      positionClass: 'toast-bottom-right'
    })
   ]
...

I can't figure out what i'm doing wrong, has anyone had similar experiences? Many thanks in advance!

Answer 1

I was able to make a minimal reproduction of your issue, and I don't see any problems: https://stackblitz.com/edit/angular-avcidu

Is it possible that you have some custom styles that conflict with the toastr.css styles, or a template that is malformed (an unclosed div, for example)?

Are you using the latest version of ngx-toastr? (9.1.1 at the time of this post)

What does your template look like?

Update:

The previous stackblitz now shows the replicated problem. Here is the link again: https://stackblitz.com/edit/angular-avcidu

Looks like both bootstrap and ngx-toastr use the .toastr class, affecting the opacity property on the toastr div.

This thread has a workable answer: Setting toastr opacity?

The answer therein is to force the opacity to 1. Add this your custom stylesheet:

#toast-container > div {
    opacity:1;
}

And here's the working stackblitz: https://stackblitz.com/edit/angular-gjazzq

When reading through this thread, I guess you could fix your problem. However, I would leave the solution to my problem here unless someone might have the same as us.

What I have done to fix the problem is: to add @import '~ngx-toastr/toastr.css'; into style.css under the root directory of the project will get rid of the issue.

Answer 3

Even after adding the opacity css code from the above answers in my global style.scss, it did not solve my problem entirely; I was getting a blank white box.

After adding the additional css mentioned in this GitHub post, the toasts are working correctly.

The relevant code from the above post is below:

/* TOASTR BUGFIX */
#toast-container > div {
  opacity: 1;
}
.toast {
  font-size: initial !important;
  border: initial !important;
  backdrop-filter: blur(0) !important;
}
.toast-success {
  background-color: #51A351 !important;
}
.toast-error {
  background-color: #BD362F !important;
}
.toast-info {
  background-color: #2F96B4 !important;
}
.toast-warning {
  background-color: #F89406 !important;
}
