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

yaktool-store-mcp

Store product CSV as an MCP server — the store-domain suite of yaktool.com.

WooCommerce imports rarely fail loudly. A row whose SKU already exists is skipped, a column the importer does not recognise is dropped, and the run still reports success. Both tools here are built around telling you what will happen before it happens. 61 documented rules (40 WooCommerce, 21 migration), each with an id, a severity and a fix. No network I/O.

Tools

  • validate_woocommerce_csv — forecast the import twice over: once with Update existing products ticked and once without, because that single checkbox is the difference between "prices updated" and "every row skipped, run reported as successful". Also lists the columns the importer will not map — where data silently disappears — and runs full GS1 validation on the GTIN column, whose bad values only surface later in a marketplace feed.
  • migrate_store_csv — convert a Shopify product export into a WooCommerce import. Handles the two things hand-rolled conversions get wrong: variable products need a parent row the export does not contain, and sale price direction is reversed between the platforms (Shopify's Compare At Price is the higher one; WooCommerce's Sale price is the lower). The output is checked by the same validator above before it is returned.
