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 🙏

Headless js renderer for kineticgraphs

Readme

Equilibria Engine

Welcome to the Equilibria Engine (equilibria-engine-js), a headless Javascript rendering engine for interactive kinetic graphs.

[!NOTE] Acknowledgement: This project is a hard fork of the excellent KGJS engine originally created by Chris Makler. The intent of the Equilibria fork is to decouple the core mathematical engine from its original monolithic application structure, making it substantially easier for developers to integrate economic models into modern websites, SPAs (React/Vue/Svelte), and custom data visualization pipelines.

Installation

npm install equilibria-engine-js

You will also need to import the engine's CSS and the KaTeX CSS (for math rendering) in your application:

import "equilibria-engine-js/dist/style.css";
import "katex/dist/katex.min.css"; 

Documentation

Comprehensive documentation has been added to assist developers in utilizing and configuring the headless engine.

Please see the local /docs directory for guides:

  1. Getting Started
  2. Architecture Overview
  3. Configuration Specification
  4. API & Interactivity

Dependencies

The engine relies heavily on:

  • D3 for drawing 2D diagrams
  • mathjs for mathematical constraint solving and evaluation
  • KaTeX for rendering mathematical typographic text (requires katex/dist/katex.min.css)
