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 🙏

Synopsis

A collapsible content module written in vanilla JavaScript.

Installation

npm install @ianhatton/vanilla-collapsible-content

Running tests

npm run test

Example Instantiation

const CollapsibleContentClass = require('@ianhatton/vanilla-collapsible-content');

const collapsibleContentElements = document.querySelectorAll('.collapsible-content');

if (collapsibleContentElements.length > 0){
  Array.from(collapsibleContentElements).map((element)=>{
    return new CollapsibleContentClass({
      element: element
    });
  });
}

Configuration

A new instance of CollapsibleContentClass can contain the following in its configuration object:

new CollapsibleContentClass({
  element: // The DOM node to be instantiated as having collapsible content
  , bodyContainerClass: // String. Class for each collapsible content item's body. Default is "collapsible-content-body"
  , itemContainerClass: // String. Class for each collapsible content item. Default is "collapsible-content-item"
  , toggleContainerClass: // String. Class for each collapsible content item's toggle. Default is "collapsible-content-toggle"
});

Example HTML structure

<div class="collapsible-content" data-name="collapsible-example" data-visible-mobile="false" data-visible-tablet="false" data-visible-desktop="true">
  <div class="collapsible-content-item" data-parent="collapsible-example">
    <div class="collapsible-content-toggle">
      <p>The toggle. This can be any element.</p>
    </div>
    <div class="collapsible-content-body">
      <p>The body. This can be any element.</p>
    </div>
  </div>
  <div class="collapsible-content-item" data-parent="collapsible-example">
    <article>
      <div class="collapsible-content-toggle">
        <h1>Another toggle.</h1>
      </div>
      <div class="collapsible-content-body">
        <p>Another body.</p>
      </div>
    </article>
  </div>
</div>

All collapsible content items must be wrapped in a single parent div with a class of collapsible-content, and individually wrapped in a div with a class of collapsible-content-item. They always contain a div with a class of collapsible-content-toggle and collapsible-content-body.

The data-name attribute of collapsible-content and data-parent attribute of collapsible-content-item determines the relationship between the two. This is in case you need to nest multiple collapsible content divs inside one another.

The data-visible- attributes of collapsible-content-item determine whether or not the items are expanded or collapsed by default at the corresponding breakpoint.

CSS

As a bare minimum, you'll require the following, or similar CSS:

.collapsible-content-body {
  display: none;
  
  &.open {
    display: block;
  }
}
