Vue page switching effect BubbleTransition

Use vue, vue-router, animejs to explain how to implement BubbleTransition of vue page switching effect. Friends who need it can refer to it

CodePen address

After using SPA on the front end, you can gain more control, such as page switching animations. Using the back-end page, we may not be able to achieve the above effects, or there will be an obvious splash screen. Because all resources need to be reloaded.

Today we use vue, vue-router, and animationjs to explain how to achieve the above effect.

Steps

1. Click on the menu to generate Bubble and start the entry animation

2. Page jump

3. Execute exit animation

Functional calling component

I hope that the effect is called through an object instead of instructions such as v-show, v-if, and to maintain uniformity, I still use Vue to write components. I usually implement this with a new Vue root node to keep the effect independent of the business components.

let instance = null
function createServices (Comp) {
 // ...
 return new Vue({
 // ...
 }).$children[0]
}
function getInstance () {
 instance = instance || createServices(BubbleTransitionComponent)
 return instance
}
const BubbleTransition = {
 scaleIn: () => {
 return getInstance().animate('scaleIn')
 },
 fadeOut: () => {
 return getInstance().animate('fadeOut')
 }
}

Then implement BubbleTransitionComponent, then BubbleTransition.scaleIn, BubbleTransition.scaleOut will work normally. Animation execution end events that animejs can listen to. anime().finished gets the Promise object.

<template>
 <p class="transition-bubble">
 <span v-show="animating" class="bubble" id="bubble">
 </span>
 </p>
</template>
<script>
import anime from &#39;animejs&#39;
export default {
 name: &#39;transition-bubble&#39;,
 data () {
 return {
  animating: false,
  animeObjs: []
 }
 },
 methods: {
 scaleIn (selector = &#39;#bubble&#39;, {duration = 800, easing = &#39;linear&#39;} = {}) {
  // this.animeObjs.push(anime().finished)
 },
 fadeOut (selector = &#39;#bubble&#39;, {duration = 300, easing = &#39;linear&#39;} = {}) {
  // ...
 },
 resetAnimeObjs () {
  this.animeObjs.reset()
  this.animeObjs = []
 },
 animate (action, thenReset) {
  return this[action]().then(() => {
  this.resetAnimeObjs()
  })
 }
 }
}

The original idea is to add a tag to a specific route meta in the router config, and then judge the tag to perform animation during beforeEach. However, this method is not flexible enough. Instead, it is marked by Hash, combined with Vue-router, and the hash is reset when switching.

<router-link class="router-link" to="/#__bubble__transition__">Home</router-link>
const BUBBLE_TRANSITION_IDENTIFIER = &#39;__bubble__transition__&#39;
router.beforeEach((to, from, next) => {
 if (to.hash.indexOf(BUBBLE_TRANSITION_IDENTIFIER) > 0) {
 const redirectTo = Object.assign({}, to)
 redirectTo.hash = &#39;&#39;
 BubbleTransition.scaleIn()
  .then(() => next(redirectTo))
 } else {
 next()
 }
})
router.afterEach((to, from) => {
 BubbleTransition.fadeOut()
})

Cool animations can catch the user’s attention in an instant. I myself often say when browsing some websites, wocao, so cool ! ! ! sigh. Maybe the final implementation won't require more than a few lines of code. I'll try to implement it myself. Next time the designer puts forward unreasonable animation requirements, I can show off. I can make this effect in minutes, but I don't think it should be used here** The animation does not meet the user’s psychological expectations.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
