A simple Vue3 directive and a wrapper component to animate elements as they appear in viewport with TypeScript
Installation
npm install @neeravp/vue-3-animate-in-view
# or
yarn add @neeravp/vue-3-animate-in-view
Setup
Import to your Vue
application
Directive
import { createApp } from "vue";
import { AnimateInViewDirective } from "@neeravp/vue-3-animate-in-view";
const app = createApp({
/*** options */
});
app.directive("animate-inview", AnimateInViewDirective);
app.mount("#app");
Directive can then be used normally on any element
<div
v-animate-inview="'fadeInSlide'"
class="w-1/2 h-96 bg-gray-500 mx-auto opacity-0"
></div>
Component
import { createApp } from "vue";
import { AnimateInViewComponent } from "@neeravp/vue-3-animate-in-view";
const app = createApp({
/*** options */
});
app.component("animate-in-view", AnimateInViewComponent);
app.mount("#app");
Component can be used anywhere in the app now
<animate-in-view animation="fadeInSlide">
<div class="w-1/2 h-96 bg-red-500 mx-auto"></div>
</animate-in-view>
Usage
Say we have declared two animations and classes to apply the animations
<style>
.fadeInSlide {
animation: fadeInSlide 1s ease forwards 0.3s;
}
@keyframes fadeInSlide {
from {
opacity: 0;
transform: translate3d(10%, 10%, 0);
}
to {
opacity: 1;
transform: translate3d(0, 0, 0);
}
}
.fade {
animation: fade 1s ease forwards;
}
@keyframes fade {
to {
opacity: 0.25;
}
}
</style>
Pass the desired class as a string literal (in single quotes) in your Vue
template:
<div v-animate-inview="'fade'">Animate me once upon scroll</div>
Scroll Direction
To apply animation only on specific scroll direction,
Directive: pass the value as object
Component: pass an object to the animation
prop.
On Downward scroll: the animation will only trigger the first time when scrolling down while element comes into the viewport.
<!-- Directive -->
<div v-animate-inview="{down: 'fade'}">
Animation will be triggered once while scrolling down when the element enters
the viewport
</div>
<!-- Component -->
<animate-in-view :animation="{down: 'fade'}">
<div>
Animation will be triggered once while scrolling down when the element
enters the viewport
</div>
</animate-in-view>
On upward scroll: the animation will only trigger the first time when scrolling up while element comes into the viewport.
<!-- Directive -->
<div v-animate-inview="{up: 'fadeInSlide'}">
Animation will be triggered once while scrolling up when the element enters
the viewport
</div>
<!-- Component -->
<animate-in-view :animation="{up: 'fadeInSlide'}">
<div>
Animation will be triggered once while scrolling up when the element enters
the viewport
</div>
</animate-in-view>
Repeat Modifier and Prop
Note that by default the animation will only trigger once: the first time the element scrolled into view.
To repeat animation everytime the element is scrolled into view:
Directive: use the repeat
modifier
Component: pass the repeat
prop
<!-- Directive -->
<div v-animate-inview.repeat="'fade'">Animate me upon scroll forever</div>
<!-- Component -->
<animate-in-view animation="'fade'" repeat>
<div>Animate me upon scroll forever</div>
</animate-in-view>
To repeat the animation everytime while scrolling down
Directive: add the repeat
modifier
Component: pass repeat
as prop
<!-- Directive -->
<div v-animate-inview.repeat="{down: 'fade'}">
Animation will be triggered while scrolling down when the element enters the
viewport
</div>
<!-- Component -->
<animate-in-view :animation="{down: 'fade'}" repeat>
<div>
Animation will be triggered while scrolling down when the element enters the
viewport
</div>
</animate-in-view>
Multiple animations
Different animations can be used for each direction:
<!-- Directive -->
<div v-animate-inview="{down: 'fade', up: 'fadeInSlide' }">
Animation will be triggered whenever element enters the viewport, scrolling in
any direction
</div>
<!-- Component -->
<animate-in-view :animation="{down: 'fade', up: 'fadeInSlide' }">
<div>
Animation will be triggered whenever element enters the viewport, scrolling
in any direction
</div>
</animate-in-view>
Note that by providing both up
and down
directions,
Directive: the repeat
modifier is implicitly set.
Component: value of repeat
prop is set to true implicitly
