Vue 3 — JavaScript Transitions

Adding transition effects with JavaScript hooks.

Vue 3 is in beta and it’s subject to change.

Vue 3 is the up and coming version of Vue front end framework.

It builds on the popularity and ease of use of Vue 2.

In this article, we’ll look at setting transition durations and creating JavaScript transitions.

Transition Durations

We can set transition durations with the duration prop.

For example, we can write:

<!DOCTYPE html>
<html lang="en">
    <script src="[email protected]"></script>
      .bounce-enter-active {
        animation: bounce-in 1.5s;
      .bounce-leave-active {
        animation: bounce-in 1.5s reverse;
      @keyframes bounce-in {
        0% {
          transform: scale(0);
        50% {
          transform: scale(1.5);
        100% {
          transform: scale(1);
    <div id="app">
      <button @click="show = !show">
      <transition name="bounce" :duration="1000">
        <p v-if="show">hello</p>
      const app = Vue.createApp({
        data() {
          return {
            show: false
