Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Vue3 Directive & Component to animate elements as they appear in viewport

Downloads

Readme

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
