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 🙏

Readme

cockle

In-browser bash-like shell implemented in a combination of TypeScript and WebAssembly.

Used in the JupyterLite terminal extension.

This is an early-stage work in progress and should be considered experimental code. Anything and everything could change at any time.

The commands used here are either built-in commands implemented in TypeScript, or WebAssembly commands compiled into .js and .wasm files. The latter are built by Emscripten-forge and are added to the cockle NPM package using a micromamba environment as part of the npm prepack process.

Build

micromamba env create -f environment-dev.yml -y
micromamba activate cockle
npm install
npm run build
npm run lint:check

Run tests

cd test
npm install
npx playwright install --with-deps chromium
npm run build
npm run test
npm run test:report

You can interactively run individual tests using npm run test:ui.

Demo

The cockle repository includes a demo so that you can easily try it out interactively in a web browser. Once you have built cockle, build and run the demo using:

cd demo
npm install
npm run build
npm run serve

then open a browser at the specified URL:
