@terriblemia/eight-ball v0.2.0

eight-ball

A Web Component for showing a random selection from a group of options (and allowing you to shake it up).

Features

Demo

Examples

General usage example:

<script type="module" src="eight-ball.js"></script>

<eight-ball>
  <span>It is certain</span>
  <span hidden>It is decidedly so</span>
  <span hidden>Without a doubt</span>
  <span hidden>Yes definitely</span>
  <span hidden>You may rely on it</span>
</eight-ball>

Installation

You have a few options (choose one):

1. Install via npm: npm install @terriblemia/eight-ball
2. Download the source manually from GitHub into your project.
3. Skip this step and use the script directly via a 3rd party CDN (not recommended for production use)

Usage

Make sure you include the <script> in your project (choose one, and update the version number as needed):

<!-- Host yourself -->
<script type="module" src="eight-ball.js"></script>

<!-- 3rd party CDN, not recommended for production use -->
<script
  type="module"
  src="https://www.unpkg.com/@terriblemia/eight-ball@0.2.0/eight-ball.js"
></script>

<!-- 3rd party CDN, not recommended for production use -->
<script
  type="module"
  src="https://esm.sh/@terriblemia/eight-ball@0.2.0"
></script>

Or use the built in WebC component with Eleventy, by adding "npm:@terriblemia/eight-ball/*.webc" to the Eleventy WebC Plugin components registry:

// Only one module.exports per configuration file, please!
module.exports = function (eleventyConfig) {
  eleventyConfig.addPlugin(eleventyWebcPlugin, {
    components: [
      // Add as a global WebC component
      "npm:@11ty/eight-ball/*.webc",
    ],
  });
}

Attributes & parts

• By default, a ::part(button) is exposed for styling.
• Optionally provide a data-action attribute to override the inner text of ::part(button)
• Optionally set data-current on one of the options to enforce an initial state
• Optionally add the (boolean) view-transition attribute to transition between values in supporting browsers.

Slots

• Any element in the default slot will be treated as an option
• If any element is marked for slot="options", the children of that element will be the options to choose from (this overrides the default slot)
• Anything in slot="action" will replace the ::part(button), and the fist button in the slot will be used as a trigger for getting a new random selection

Properties & methods

• EightBall.options (read-only, array): the collection of elements to select from
• EightBall.action (read-only, HTMLButtonElement): the action button that controls the eight-ball
• EightBall.actionText (read/write, string): the action button's inner text
• EightBall.current (read/write, HTMLElement): the currently selected option, if any
• EightBall.onDeck (read-only, array): the options that have not yet been displayed (or all non-current options, once all have been seen)
• EightBall.shake(): hide the current selection, and show a new one from the list of options currently on-deck!

ToDo

Things we might need…

• Allow moving the action before the options?
• More repeat options (maybe data-repeat):
  • cycle: the current behavior
  • always: everything is always 'on-deck'
  • never: only go through the options once???
