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 🙏

Readme

@jcayzac/astro-classlist

Coerce Astro's class:list into an array of strings.

license npm version npm downloads bundle

This module provides a single utility for Astro components, that coerce a value received as a class:list prop into an array of strings.

You probably need this if your component receives a class:list prop and passes it to a child component, and if you want to add other classes to the list.

Because class:list can be an object or an iterable and contain things other than strings, it can get a bit messy if you want to add something to that.

// This is what you normally get from Astro
type AstroBuiltinAttributes['class:list'] =
  | string
  | Record<string, boolean>
  | Record<any, any>
  | Iterable<string>
  | Iterable<any>
  | undefined

// This is what you get when using this utility
type ClassList = string[]

Installation

# pnpm
pnpm add @jcayzac/astro-classlist

# bun
bunx add @jcayzac/astro-classlist

# npm
npx add @jcayzac/astro-classlist

# yarn
yarn add @jcayzac/astro-classlist

# deno
deno add npm:@jcayzac/astro-classlist

Usage

---
import type { AstroBuiltinAttributes } from 'astro'
import ChildComponent from '@components/ChildComponent.astro'
import { ClassList } from '@jcayzac/astro-classlist'

interface Props {
  'class:list': AstroBuiltinAttributes['class:list']
}

const { 'class:list': classList } = Astro.props as Props

const classes: string[] = ClassList.toArray(classList)
---
<ChildComponent class:list={['mx-auto', ...classes]} />
