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 🙏

meta-map-widget: a self-contained map widget showing user-selectable metadata

PSMapWidget is a javascript Leaflet widget used to map and analyze locations associated with user-defined metadata.

Installation and Setup

This repository can be accessed and downloaded from Github. There is currently no distribution on NPM, but you can clone this repository and run npm install.

Usage

alt text

The widget once run with NPM appears as above. This creates an interactive HTML Leaflet widget (map data provided by OpenStreetMap) which displays the location source of each individual datapoint. The color and size of map markers are determined by user-selected variables from the dropdown. Clusters of nearby points are automatically grouped and represented as pie charts, depending on zoom level. The pie chart markers are representative of the sample data in each respective cluster. Pie charts represent frequencies of the color variable, and the icon size is an average of values of the size variable.

alt text

You can also choose to focus in on individual data points. Selecting an individual marker will bring up a popup with the values of all data associated with that location.
