@modular-css/svelte

Svelte preprocessor support for modular-css.

Process inline <style type="text/m-css"> or <link> or import styles from "./foo.css"; references inside your Svelte components using the full power of modular-css. Dynamic references will be replaced where possible with static ones, allowing for greater compile-time optimizations, smaller bundles, and even faster runtime performance!

Turns this

<div class="{css.main}">
    <h1 class="{css.title}">Title</h1>
</div>

<style>
    .main {
        ...
    }

    .title {
        ...
    }
</style>

into what is effectively this

<div class="abc123_main">
    <h1 class="abc123_title">Title</h1>
</div>
