This plugin is a starting point for creating any plugin that relied in modern PHP development, such as OOP, Composer, and PHPUnit.
Before anything, install dependencies by running composer install && npm install, then choose the mode you want to use:
Run npm run dev. This will watch for changes on admin/assets/src and will build them in the admin/assets/build folder in a non-minify/uglify way.
Run npm run build. This will build files in admin/assets/src to admin/assets/build, the files will be placed in a minify-uglify way, ready to use.
Umm, not really, it's just a personal project, however, if you still want it, just create a PR and I'll take a look.
