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 🙏

Readme

reveal-on-scroll

NPM version Actions Status PR Welcome

Lightweight library to reveal elements on scroll.

Also SSR safe and won't break build if pre-rendered.

Installation

Install this package with npm.

npm i @phntms/reveal-on-scroll

Usage

To use, initialize a new RevealOnScroll() component.

import RevealOnScroll from "@phntms/reveal-on-scroll";

new RevealOnScroll();

// Or...

new RevealOnScroll({
  /**
   * If multiple elements are visible at same time, this defines the delay
   * before showing next element.
   *
   * Set to 0 to remove default stagger.
   */
  delayBetweenQueuedElements: 150,

  // Threshold of element that has to be in view, before revealing element
  thresholdToRevealElements: 0.2,

  // Used to querySelectAll with the following
  revealSelector: ".reveal-on-scroll",

  // Class added to element when revealed
  visibleClass: "reveal-scrolled",

  // If used alongside revealSelector, ignores reveal events till removed
  hiddenClass: "reveal-hidden",
});

Then to use, simply add the reveal-on-scroll class to any HTMLElement. For example:

<div class="reveal-on-scroll"></div>

Additionally use reveal-hidden to prevent elements being revealed till ready, for example the following won't be revealed until reveal-hidden is removed:

<div class="reveal-on-scroll reveal-hidden"></div>

🍪 Recipes:

The library works by adding reveal-scrolled to any reveal-on-scroll elements.

To animate, simply hook into this with any custom CSS, for example:

.reveal-on-scroll {
  opacity: 0;
  transform: translateY(32px);
  transition: opacity 0.8s, transform 0.6s;
  transition-timing-function: cubic-bezier(0.3, 1, 0.7, 1);

  &.reveal-scrolled {
    opacity: 1;
    transform: translateY(0);
  }
}

Browser Support

This library utilizes intersectionObserver, as such browser support is pretty good (par IE11 and below), for more information check caniuse. For fallback, reveal-scrolled is automatically added to all reveal-on-scroll elements to ensure older browsers still reveal content.

If you need reveal-on-scroll to work on any browser that doesn't support intersectionObserver consider using a polyfill such as - intersection-observer.
