A simple Vue 3 directive that animates elements as they scroll into view.
npm install vue-animate-onscrollimport { createApp } from 'vue'
import VueAnimateOnScroll from 'vue-animate-onscroll'
const app = createApp(App)
app.use(VueAnimateOnScroll)
app.mount('#app')For demo purposes, let's use animate.css, a CSS animation library, but using your own custom CSS animations would work the same way.
Import animate.css however you like. For example, in your index.html:
<head>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/4.1.1/animate.min.css">
</head>Pass the desired class as a string literal (in single quotes) in your Vue template:
<div v-animate-onscroll="'animate__animated animate__flip'">Animate me once upon scroll</div>To trigger the animation with an offset at the top and the bottom, add a data-animate-onscroll-offset attribute:
<div v-animate-onscroll="'animate__animated animate__flip'" data-animate-onscroll-offset="100">Animate me with 100px offset</div>By default the animation triggers once. To repeat it every time the element scrolls into view, use the repeat modifier:
<div v-animate-onscroll.repeat="'animate__animated animate__flip'">Animate me forever</div>For in and out animations on scroll, use in and out keys:
<div v-animate-onscroll.repeat="{in: 'animate__animated animate__flipInX', out: 'animate__animated animate__flipOutX'}" data-animate-onscroll-offset="100">Flip in and out</div>Animate only on a specific scroll direction:
<div v-animate-onscroll="{down: 'animate__animated animate__flip'}">Animate once on scroll down</div>
<div v-animate-onscroll="{up: 'animate__animated animate__rotateOut'}">Animate once on scroll up</div>With repeat:
<div v-animate-onscroll.repeat="{down: 'animate__animated animate__flip'}">Animate every scroll down</div>Use two different animations for each scroll direction:
<div v-animate-onscroll="{down: 'animate__animated animate__flip', up: 'animate__animated animate__rotateOut'}">Different animations per direction</div>Note: providing both up and down implicitly enables repeating.
