Active Link

A Svelte Action that lets you style links. Use it on a wrapping element. It targets all <a>-tags inside it and add data-attributes to links inside the wrapping element.

Why it's awesome:

• Does not think /carbon is a descendant of /car
• Let's you style both the active link, it's descendants and it's ancestors.

Installation

pnpm add --save-dev npm i @fabianmossberg/active-link

Usage

Import the action and it on an element wrapping the links.

<script lang="ts">
    import { activeLink } from '@fabianmossberg/active-link';
</script>

<ul use:activeLink>
	<li><a href="/">Home</a></li>
	<li>
		<a href="/a">A</a>
		<ul>
			<li><a href="/a/aa">AA</a></li>
		</ul>
	</li>
	<li><a href="/b">B</a></li>
	<li><a href="/car">Car</a></li>
	<li><a href="/car/tesla">Tesla</a></li>
	<li><a href="/carbon">Carbon</a></li>
	<li><a href="/b" data-never-active>B</a></li>
</ul>

Style it with css

/* Will be applied the active link as well as it's descendant and ancestors */
[data-active] {
    background-color: yellow;
}

/* Will be applied to the active link */
[data-active="active"] {
    color: black;
	border:2px solid red;
    font-weight: 900;
}

/* Will be applied to links that are ancestors of the active link. */
[data-active="ancestor"] {
    color: rgb(172, 86, 52);
}

/* Will be applied to links that are decendants of the active link. */
[data-active="descendant"] {
    color: rgb(55, 84, 211);
}
