Angular 5 animation specific transitions

So my problem is I want to specify a specific animation between to pages.

I want to do one sort of animation when I click on a button which navigate to a specific URL(I am on page1 and navigate to page2) http://localhost:4200/page2. Then if I am on page1 and want to do goBack() I want a different animation when I return on the home page http://localhost:4200.

But with the :leave option of transition I can't achieve my goal, because I will have just one type of animation. My idea is to do something like that: 

trigger('zoomAndFade', [
  transition( 'page1=> page2', [
    query('.content', [
      style({fontSize: '1em', opacity: 1}),
      animate('2s ease-in-out', style({fontSize: '1.5em', opacity: 0}))
    ])
  ])

trigger('fade', [
  transition( 'page2=>page1', [
    query('.content', [
      style({opacity: 1}),
      animate('2s ease-in-out', style({opacity: 0}))
    ])
  ])

but how can I specify the state of a page to the animation ?

This is possible. Just add this getState methode to your app.component.

app.component.ts

export class AppComponent {
    getState(outlet) {
        return outlet.activatedRouteData.state;
    }
}

In your template, you need to get the new state of the router on a change event.

app.component.html

<main [@routerTransition]="getState(o)">
    <router-outlet #o="outlet"></router-outlet>
</main>

Now the animation in you component can distinguish between your pages.

Then you can have your transistions

trigger("routerTransition", [
    transition("* => settings", slideLeft),
    transition("settings => *", slideRight),
])

But your router needs to transmit data

{
    path: "settings",
    component: SettingsComponent,
    data: { state: "settings" }
}

And you animation can now feature :enter and :leave

query(":enter",
    [
        style({
            transform: "translateX(100%)"
        }),
        animate("0.4s ease-in-out",
            style({
                transform: "translateX(0%)"
            })
        )
    ], {
        optional: true
    }
),
query(":leave",
    [
        style({
            transform: "translateX(0%)"
        }),
        animate("0.4s ease-in-out",
            style({
                transform: "translateX(-100%)"
            })
        )
    ], {
        optional: true
    })
