javascript - Grunt, how to minify different folders (to include node_modules folder) -

i using npm in wp project.

i have grunt task compiles separate scss files css files , minifies them 1 default.min.css file when running grunt (that's good.)

my main issue include different npm packages such fontawesome, bootstrap etc. minified 1 minified min.css file, own files.

i know how own *.js files uglify'd different packages i'm using (jquery-ui, owl-carousel, etc.)

please find below gruntfile.js, first gruntfile.js feel free include constructive remarks.

thanks, bud
