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 🙏

Token-driven Astro UI component system

Readme

Astro UI System

A token-driven, class-based UI system for Astro.

Philosophy

  • Token-first: primitives, semantics, and component tokens are layered CSS variables.
  • Class-only variants: all component variants resolve to pre-defined classes.
  • Global radius control: one semantic token (--aui-radius-base) controls rounding across the system.
  • No runtime styling engine: no Tailwind and no inline-style API.

Installation

npm install @mmnl.crngl/astro-ui astro

Import root styles once:

import '@mmnl.crngl/astro-ui/styles.css';

Token System

  • src/tokens/primitive.css defines spacing, color, type, shadow, z-index.
  • src/tokens/semantic.css maps design meaning and dark theme overrides.
  • Component tokens and styles are co-located with their respective components for optimal on-demand CSS rendering.

On-Demand CSS Rendering

Component styles are automatically included only when their respective components are imported. This means:

  • Smaller CSS bundles - only styles for imported components are included
  • Better tree-shaking and code splitting
  • Improved performance through automatic optimization

Simply import the components you need:

import { Button, Card } from '@mmnl.crngl/astro-ui';

Only Button and Card styles will be included in your bundle.

Layout Usage

---
import { Container, Stack, Grid, Box } from '@mmnl.crngl/astro-ui';
---

<Container>
  <Stack gap="md">
    <Grid cols={3}>
      <Box surface={true}>Card 1</Box>
    </Grid>
  </Stack>
</Container>

Theming

Dark mode tokens are enabled with:

<html data-theme="dark">

Custom brand profiles can override semantic tokens:

:root[data-brand='flat'] {
  --aui-radius-base: 0px;
}

Radius Override

Set --aui-radius-base at root or container scope to globally tune the corner style without touching components.

Roadmap

  • Phase 1: foundation ✅
  • Phase 2: controls ✅
  • Phase 3: feedback ✅
  • Phase 4: composites ✅ (interaction behavior to be deepened)
  • Phase 5: release docs + playground
