vue.js remove element after transition

Question

I'm creating a sort of notification system inside my webpage with vue.js All works fine but i want to remove the element after the transition is completed. I only get this to work with an setTimeout but that is not the ideal method

Working jsfiddle: http://jsfiddle.net/yMv7y/1073/

This is my code:

Vue:

Vue.transition('notification', {
    enter: function(el) {
        app.notifications.pop();
    },
    leave: function(el) {
        setTimeout(function(){
            el.remove();
        },5000);
    },
});

Vue.component('notification', {
    template: '<div class="notification" v-class="red: !success, green: success" v-transition="notification"><p>{{message}}</p></div>',
    data: function() {
        return {
            success: true,
            message: '',
        };
    },
});

var app = new Vue({
    el: 'body',
    data: {
        notifications : [
        ]
    },
    ready: function() {
        self = this;
        var data = {
            'message': 'Thank you',
            'success': true
        };
        self.notifications.push(data);
    },
});

Html:

<div id="notifications-wrapper">
    <notification id="notification"
            v-repeat="notifications"
            >
    </notification>
</div>

CSS #notifications-wrapper { position: fixed; z-index: 99; top: 0; left: 80%;

overflow: visible;
}

.notification
{
position: relative;
z-index: 100;

overflow: hidden;

width: 250px;
margin-top: 20px;
transform: translate(20px, 0);
animation-fill-mode: forwards;
transition: 1s;
-webkit-backdrop-filter: blur(2px);
        backdrop-filter: blur(2px);
background-color: grey;
}

p 
{
margin: 10px 20px;

color: $white;
}



.notification-transition
{
animation-delay: 0s, 4.5s;
animation-duration: 4.5s, 0.5s;
animation-name: slide-in-out, hide-notification;
}


@keyframes slide-in-out
{
0%
{
    transform: translate(20px, 0);
}
10%
{
    transform: translate(-270px, 0);
}
90%
{
    transform: translate(-270px, 0);
    opacity: 1;
}
100%
{
    transform: translate(20px, 0);
    opacity: .5;
}
}

@keyframes hide-notification {
1% {
  height: auto;
  margin-top: 20px;
}
100% {
    height: 0;
    margin: 0;
}
}

Answer 1

Problem: You tried to remove el during the transition( leave function ) so you got error without setTimeout.

Solution: You have to use afterLeave function . Change leave function to afterLeave function .

afterLeave: function(el) {

        el.remove();
}
