This project will allow you to preview PurgeCSS configurations against a project directory and allow you to identify unused selectors. Nothing will be removed, however, the audit will generate a logfile that will allow you to fine tune the config (especially the safelist property) to get the desired result.
To use this script, provide the command line parameters as described below when running the script:
--config, -c <path>: This option allows you to specify the path of the configuration file for PurgeCSS.
--project-base, -b <path>: This is the path to the base directory of the project you are auditing.
--output, -o <path>: Here, you can specify the path to your output log file where the results will be stored.
It outputs the details of unused CSS properties into the specified log file. If a safelist is specified in the PurgeCSS configuration, it will not log any classes or IDs that have been added to the safelist.
npm install;
node ./index.js -o ./unused-css.txt -c /path/to/purgecss/config.js -b /path/to/project/directory;
