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 🙏

Read-only browser for curated @mit-sdg/sync-engine designs and source

Readme

@mit-sdg/sync-engine-catalog

sync-engine-catalog is a read-only browser for curated sync-engine concept and recipe source. It prints designs and explicitly selected source files so you can decide whether and where each asset belongs. It has no runtime import API and never writes to the current project.

Install it as a development dependency, then browse a design before choosing source:

bun add --dev --exact @mit-sdg/[email protected]
bunx --no-install sync-engine-catalog list
bunx --no-install sync-engine-catalog show concept/labeling
bunx --no-install sync-engine-catalog show recipe/review-queue
bunx --no-install sync-engine-catalog source concept/labeling memory/labeling.memory.ts

show labels the entry's design and lists selectors accepted by source. Concept implementation selectors include their implementation name:

bunx --no-install sync-engine-catalog source concept/selecting memory/selecting.memory.ts

Use --raw when stdout must contain only selected file bytes:

bunx --no-install sync-engine-catalog show concept/selecting --raw
bunx --no-install sync-engine-catalog source concept/selecting selecting.shared.ts --raw

The printed names identify inspiration, not a required name, contract, or destination. Copy only what the application needs: a design may be simplified, split, combined, renamed, or rejected. Recipe designs show a complete static instance inventory for their stated concept selection; adapt that inventory and every binding to the exact assembly variant you actually select. Browse implementation source only after choosing an approved concept to implement; examples may contain behavior outside an application's scope.

The recommended application layout uses design/concepts/*.md, design/compositions/*.md, design/types.md, concept source under src/concepts/<name>/, and paired composition modules under src/compositions/. The catalog neither assumes nor creates that layout. Recipe assets import adjacent Markdown and export it as spec. They use an entry-local relative import because one packaged catalog typecheck covers many independent entries, while an application-owned @design/* alias has application-specific targets.

Support

Stable 1.x follows Semantic Versioning for the documented command and manifest contracts. Only the newest stable 1.x release receives fixes. Catalog entries are adaptable examples, not additional framework API contracts; pin the package when coursework depends on exact entry contents. See the support policy and private security reporting process.

See public-surface.md for the exact command and manifest contract. Entry authors should read CONTRIBUTING.md.
