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 🙏

postcss-color-hsla-fallback

PostCSS plugin to transform hsl() and hsla() to hexadecimal.

Inspiration for this plugin comes from postcss-color-rgba-fallback

Installation

With npm:

npm install postcss-color-hsla-fallback --save-dev

or with yarn:

yarn add postcss-color-hsla-fallback --dev

Also make sure you have postcss installed:

npm install postcss --save-dev
yarn add postcss --dev

Usage

const fs = require('fs');
const postcss = require('postcss');
const colorHslaFallback = require('postcss-color-hsla-fallback');

const css = fs.readFileSync('input.css', 'utf8');

const output = postcss()
  .use(colorHslaFallback())
  .process(css)
  .css;

Using this input.css:

body {
  color: hsl(0, 53%, 41%);
}

you will get:

body {
  color: #a03131;
  color: hsl(0, 53%, 41%);
}

Options

preserve (default: true)

Allows you to preserve the original hsl() or hsla() colors in the output.

Possible values:

  • true: Keeps hsl() and hsla() values in the output.
  • false: Removes hsl() and hsla() values from the output and replaces them with their hex computed values.

With preserve: false you will get:

body {
  color: #a03131;
}

skipProperties (default: '[]`)

Allows you to skip specific properties from the list so that they are not replaced with their hex computed values.

Possible values includes one or more from this list:

[
  'background-color',
  'background',
  'border-bottom-color',
  'border-color',
  'border-left-color',
  'border-right-color',
  'border-top-color',
  'border',
  'caret-color',
  'color',
  'column-rule-color',
  'column-rule',
  'filter',
  'outline-color',
  'outline',

]
