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 🙏

@trackunit/react-map-color-utils

Browser-backed CSS color utilities for the Trackunit map stack. Resolves and mixes colors using the native CSS color-mix() function via a hidden DOM probe element, with caching so each unique expression is computed at most once.

Installation

npm install @trackunit/react-map-color-utils

API

| Function | Description | |---|---| | mixColor(color1, color2, percentage) | Mix two CSS colors using color-mix(in srgb). Returns the resolved rgb() string, or color1 on failure. | | darkenColor(color, amount) | Darken a CSS color by mixing it with black (0 = no change, 100 = pure black). | | lightenColor(color, amount) | Lighten a CSS color by mixing it with white (0 = no change, 100 = pure white). | | colorWithOpacity(color, opacity) | Apply an opacity multiplier (0–1) to the alpha channel of a resolved CSS color. | | resetColorUtilsForTesting() | Clear the color cache and detach the probe element. Test teardown only. |

Notes

  • Requires a browser environment (document, getComputedStyle). Returns the fallback/original color in SSR or when the browser rejects an expression.
  • Output is normalized to rgb()/rgba() — modern browsers may return color(srgb …) from getComputedStyle, which is converted for compatibility with Mapbox GL JS and similar renderers.

Part of the @trackunit/react-map family
