Colophon

I used SolidStart to scaffold an empty SolidJS TypeScript project with Vite. I downloaded the "SR Legacy" data set from the USDA FoodData Central site. This data set is fairly complete, but it's still small enough that I can serve and load a condensed version for fully client-side lookups. I used FuseJS to search this data set - its tuneable fuzzy search and small bundle size were perfect for the project's needs.

This was my first experience with SolidJS stores, and I found the developer experience wonderful. It turned out to be an efficient and simple way to reactively manage the dynamic form state I required.

I adapted a fraction-parsing script from StackExchange user machineghost to allow the quantity to be written as a mixed fraction. And that was it. You can see the results at the bottom of my bread pudding and breakfast strata posts.
