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 🙏

Bar Chart Web Component

A web component for creating bar charts on web pages.

Usage

Basics

In order to use the web component you will need to add the script file to your web page

<head>
	...
	<script src="node_modules/bar-chart-web-component/BarChart.js"></script>
	...
</head>

Then add a <bar-chart> element to your page containing one or more <data-series> elements

<bar-chart>
	<data-series>
		<data-point label="2025-Oct-01" value="2"></data-point>
		<data-point label="2025-Oct-02" value="15"></data-point>
		...
	</data-series>
</bar-chart>

You can add axis labels and ticks using the attributes

<bar-chart
	dependent-axis-label="Commits Per Day"
	dependent-axis-ticks="5"
	independent-axis-label="October 2025"
>

See also the Basic Example

Styling

By default <bar-chart> should pick up on your site's theme including dark/light mode if you use common css variable names in particular

  • --rule-color (used for the axis)
  • --primary-text-color (used for the labels)
  • --secondary-background-color (used for the chart background, defaults to transparent)
  • --primary-accent-color (used for the color of the bars, defaults to a blue)

See Basic Example and Multi-Series Example

When you have multiple data series it is generally helpful to use different colors for each series. You can set the color of a data series using the color attribute on the <data-series> element which accepts any css color specification including named colors.

<data-series color="orange">

See the Multi-Series Example

Sometimes you want your chart to stand out a bit more though. In this case you can select label, axis, background, and default bar color.

bar-chart {
	--bar-chart-axis-color: #00F;
	--bar-chart-label-color: #999;
	--bar-chart-background-color: #FDF5E6;
	--bar-chart-default-bar-color: orange;
}
