Data Collection

Data is scraped from string manufacturer websites via scripts. To scrape the latest (most likely won't change), run:

npm run scrape

Based off of the defintions in types.json, a parser from ./parsers is used, after being passed in the $ cheerio function, as well as any additional arguments spread via parserArgs in the definition.

For sites unscrapable, like D'Addario's PDFs, they live in ./scripts, to be pasted into developer tools (recommend Firefox to call copy(results) afterwards for adding to clipboard.

Testing

npm test
