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 🙏

Play with the settings of the horiz-gauge by visiting the horiz-gauge playground.

Install in your Node project with

and use it inside your code via

or, alternatively

Create the new gauge objects via

Parameters

  • settings Object The configuration object for the gauge. All data for the gauge is provided with this object.
    • settings.svg Object The DOM tree element, wich must be an svg tag. The gauge will be attached to this DOM tree element. Example:settings.svg = document.getElementById('gauge');'gauge' is the id of a svg tag.
    • settings.id String? The id of a domtree svg element, to which the gauge will be bound to. The id will only be used in case settings.svg is not provided.
    • settings.fraction Number? Progress indication for the gauge. A value of 0 is indicating no progress, 1.0 is indicating completion. Default is 0.0
    • settings.fractionLabel String? A label to show for the progress fraction. Default is ''.
    • settings.fractionColor String? The color for the fraction indication. Default is '#222'
    • settings.fractionExceedColor String? The color to use in case fraction > 1.0.
    • settings.emptyColor String? Color for the non-progress area of the gauge. Default is borderColor
    • settings.emptyPattern Boolean? When true, the empty area will be a pattern made of fractionColor and emptyColor
    • settings.progressWidth Number? Width in pixels for the progress gauge without borders and margins. Default is 200.
    • settings.progressHeight Number? Height in pixels for the progress gauge without borders and margins. Default is fontSize + 2.
    • settings.borderColor String? Color of the border of the progress gauge. Default is '#ccc'
    • settings.borderWidth Number? Width in pixels for the border of the progress gauge. Default is 0
    • settings.fontSize Number? Size in pixels for all labels. Default is 16
    • settings.fontFamily String? The font to use for all labels. Default is sans-serif.
    • settings.margin {top: Number, right: Number, bottom: Number, left: Number}? The margin for the gauge. Markers and labels are drawn inside of the margin. Default values are:settings.margin = { top: 0, right: 0, bottom: 0, left: 0 }
    • settings.leftLabel {label: String, color: String, textAnchor: String}? A label to put to the left of the progress gauge. Must fit into the left margin. Allowed values for textAnchor are 'start', 'middle', 'end'. Default values are:settings.leftLabel = { label: '', color: '#222', textAnchor: 'start' }
    • settings.rightLabel {label: String, color: String, textAnchor: String}? A label to put to the right of the progress gauge. Must fit into the right margin. Allowed values for textAnchor are 'start', 'middle', 'end'. Default values are:settings.rightLabel = { label: '', color: '#222', textAnchor: 'start' }
    • settings.markers Array<{fraction: Number, label: String, color: String, position: String, distance: Number, textAnchor: String}>? Highlight fractions outside of the gauge. Each marker is an object with a fraction for the marker and some optional settings. A marker must fit into the margins of the gauge. Allowed values for position are 'top', 'bottom' Allowed values for textAnchor are 'start', 'middle', 'end' Example:settings.markers = [ { fraction: 0.0, label: 'G1', distance: 20 }, { fraction: 0.2, label: 'G2' }, { fraction: 0.8, label: 'G3', color: 'lightgray', position: 'bottom', textAnchor: 'start'}];
    • settings.dividers Array<{fraction: Number, color: String}>? Highlight fractions inside of the gauge. Each divider is an object with a fraction and an optional color. The default for color is emptyColor. Example:settings.markers = [ { fraction: 0.1 }, { fraction: 0.2, color: 'green' }, { fraction: 0.8, color: 'red'}];
