Current behavior

I have the following animation in Angular 6.

slide-in-out-animation.ts

    // import the required animation functions from the angular animations module
import { trigger, state, animate, transition, style } from '@angular/animations';

export const slideInOutAnimation =
  // trigger name for attaching this animation to an element using the [@triggerName] syntax
  trigger('slideInOutAnimation', [

    // end state styles for route container (host)
    state('*', style({
      // the view covers the whole screen with a semi tranparent background
      position: 'fixed',
      zIndex: 6,
      top: 0,
      left: 0,
      right: 0,
      bottom: 0,
      backgroundColor: 'rgba(0, 0, 0, 0.8)'
    })),

    // route 'enter' transition
    transition(':enter', [

      // styles at start of transition
      style({
        // start with the content positioned off the right of the screen, 
        // -400% is required instead of -100% because the negative position adds to the width of the element
        right: '-400%',
        zIndex: 6,

        // start with background opacity set to 0 (invisible)
        backgroundColor: 'rgba(0, 0, 0, 0)'
      }),

      // animation and styles at end of transition
      animate('.5s ease-in-out', style({
        // transition the right position to 0 which slides the content into view
        right: 0,
        zIndex: 6,

        // transition the background opacity to 0.8 to fade it in
        backgroundColor: 'rgba(0, 0, 0, 0.8)'
      }))
    ]),

    // route 'leave' transition
    transition(':leave', [
      // animation and styles at end of transition
      animate('.5s ease-in-out', style({
        zIndex:6,
        // transition the right position to -400% which slides the content out of view
        right: '-400%',

        // transition the background opacity to 0 to fade it out
        backgroundColor: 'rgba(0, 0, 0, 0)'
      }))
    ])
  ]);

When I want to use the animation in a Component:

@Component({
      selector: 'app-example-edit',
      templateUrl: './example-edit.component.html',
      styleUrls: ['./example-edit.component.css'],

      // make slide in/out animation available to this component
      animations: [slideInOutAnimation],

      // attach the slide in/out animation to the host (root) element of this component
      host: { '[@slideInOutAnimation]': '' }
    })
export class ExampleComponent {

}

In parent-component.html I have the html

<a href="#" routerLink="add">Add</a>
<div class="view-side-form">
  <router-outlet></router-outlet>
</div>

In the parentcomponent I have a link to add a element. When the user click in the link. The content of examplecomponent is loaded using the animation. In chrome is working perfect. But in Internet Explorer the animation is not working. Also, the animation is working perfect using Angular5 in Chrome and IE. The problem is when i want to use it with Angular 6.

In Angular5 is working perfect in all browsers, but when I want to migrate to Angular6 i have problems with IE. No errors in IE console.

Minimal reproduction of the problem with instructions

You can reproduce the problem in the following link: https://stackblitz.com/edit/angular-grryts

There is also a problem in IE that ng-components aren’t removed when routing animation is done. Thus, all ng-componets stay in the DOM even if we left the route. Not sure if a separate ticket should be created for that.

@jackmusick After what feels like a lifetime of debugging, I know what was causing this for me so maybe it will help you.

I have dynamic components in my template that I don’t want to be removed from the DOM while the page is being navigated away from (it looks weird). In order to prevent them from being hidden, I added a block to my animation that look like this: query(':leave ng-component', [animate('1.5s')], {optional: true})

This worked in all browsers besides IE. So I dug into the code. Because IE requires polyfilling, it uses CssKeyFrames instead of WebAnimations. CssKeyFrames generates CSS for my code that looks like this:

@keyframes gen_css_kf_1 {
    0% {}
    100%{}
}

Angular is relying on the animationend event to remove elements from the DOM. IE never triggers the animation end event when there are no animatable properties in the block (for instance: display block -> display block also does not trigger the animationend event).

Until Angular puts in a fix, I have resolved this by adding animatable properties to my ng-component query:

query(`:leave ng-component`, [animate('1.5s', style({ transform: 'translateY(0%)' }))], { optional: true })
