Debugging
The frontend tooling is packaged by Vite. In lieu of a watch mode, Electron points the front end at the Vite http server. This has the advantage of supporting HMR.
To run from VS Code, run npm run debug in a terminal to run the Vite server.
To run everything in one go use npm start.
Database Construction
The info about lego parts and their attribtues is build in steps.
The LEGO.com Pick a Brick presents pieces (about fourteen thousand) with a number of attributes. LEGO does not provide this information in a more conventient format, so it is scraped using Puppeteer. The color table is obtained from the HTML color table on swooshable.com.
node srcipts/ScrapeLego.js lego-data/new-scrape-data.ndjson
curl 'https://swooshable.com/parts/colors' > lego-data/colors.html
The initial database is then build in a series of steps.
./scripts/BuildColorFamilies.js lego-data/new-scrape-data.ndjson > lego-data/color-families.json
./scripts/LoadSchema.ts
./scripts/LoadColors.ts
./scripts/LoadParts.ts
