• make sure to yarn add purgecss first
• usage is (hooks/purge-css {:css-source __ :js-globs __ :out-dir __})
  • :css-source is the path to the original, bloated CSS file (from project root). This is ideally in a source directory, or node_modules as in this example. This cannot be the public path where the css is ultimately read.
• :js-globs is a string / vector of strings, indicating which files to read as input. These should be all of your compiled javascript bundles which contain your views. purgecss does a brute-force parse of all these files, extracting all the strings to figure out which clas
