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 🙏

CSS demo build tool

Readme

zoetrope is a tool for building CSS demos. Imagine something like Codepen, except:

  • It runs locally on your own computer
  • You use your normal text editor
  • You can't add any HTML or JS. Only CSS.

That last one is super important. CSS demos that depend on JavaScript or lots of little helper <div /> elements are great, but I think it's also fun to try without that stuff, and get creative within the boundaries of what CSS can do all on its own. Working with PICO-8 taught me how platform constraints can actually inspire creativity rather than stifle it. zoetrope is a way for me to bridge the gap and try to bring some of that thinking into the stuff I do on the web.

This is more of a personal tool, and not really intended for widespread public adoption. It's open source because it might as well be, and it has this documentation because I don't like open sourcing things without any. You're more than welcome to give it a try, and I'd be really excited if anybody did. But that's not really the goal here!

Installation

yarn add -D @hendotcat/zoetrope

Usage

 zoetrope <command>

 Commands
   help    print this help text
   build   build static site
   server  run development server

I wanted to optimize out as much tooling boilerplate as possible from my workflow, so zoetrope pulls all the metadata it needs to build a demo from package.json. Check out the package.json for my doomfire demo for example. Most of the values in there are actually used in the built version of the demo at https://hen.cat/doomfire. I'm not going to document the setup process in detail, but if you do want to try out zoetrope for yourself then go and browse around that repository for a moment.
