<share-to-mastodon>

a small lit-based web component that uses <dialog> to allow setting of a target Mastodon instance from a user to allow sharing from your website.

Features

1. Allows user to define their instance or select from a datalist that is present or custom set (the power of input type=url list and datalist! yeah web platform)
2. Will remember the selected instance if selected by the user per the installed domain (no cross-domain sharing)
3. No User Tracking: it's all local, let's keep it real people
4. Lots of custom css props, every string can be overridden
5. New in v2.0.0: Bare metal speed, now with <dialog>!

A Basic Example

By default, the component renders whatever you feed the <slot>, wrapped internally as a <a>:

<share-to-mastodon message="My website is amazing, come check it out!" url="https://justinribeiro.com">
  Share to Mastodon
</share-to-mastodon>

A More Advanced Style Example

If you're looking for something more button-like, congrats, the slot let's you make the magic happen:

<style>
  .myMagicalCss > div {
    display: inline-flex;
    justify-content: center;
    align-items: center;
    padding: 0.5rem;
    background: lightblue;
    border-radius: 5px;
    border: 1px solid #ccc;
  }
  .myMagicalCss > div:hover {
    background: #eee;
  }
  .myMagicalCss svg {
    width: 24px;
    margin-right: 0.5rem;
  }
</style>
<share-to-mastodon class="myMagicalCss">
