Minifying bower_components js files I am currently using spoeken's gulp workflow (https://github.com/spoeken/gulp-craftcms). Everything works well in development, however, when it comes to production, I can't seem to concat/minify my bower_components dependencies, into one file. 

I currently have a public/resources/js/app.min.js, however, my bower_component dependencies are sitting in app/resources/bower_components. 

How do you go about minifying my dependencies into one file? 

Here's what I have in my package.json file:

{
  "name": "craftgulp",
  "version": "0.0.0",
  "authors": [
    ""
  ],
  "license": "MIT",
  "private": true,
  "dependencies": {
    "jquery": "~2.2.0",
    "tether": "^1.4.0",
    "bootstrap": "v4.0.0-alpha.2",
    "gsap": "^1.19.1",
    "scrollmagic": "^2.0.5",
    "slick-carousel": "^1.6.0",
    "waypoints": "^4.0.1"
  },
  "overrides": {
    "bootstrap-sass": {
      "main": [
        "assets/stylesheets/_bootstrap.scss",
        "assets/fonts/bootstrap/*",
        "assets/javascripts/bootstrap.js"
      ]
    },
    "scrollmagic": {
      "main": [
        "./scrollmagic/uncompressed/ScrollMagic.js",
        "./scrollmagic/uncompressed/plugins/animation.gsap.js",
        "./scrollmagic/uncompressed/plugins/debug.addIndicators.js",
        "./scrollmagic/uncompressed/plugins/jquery.ScrollMagic.js"
      ]
    },
    "gsap": {
      "main": [
        "./src/uncompressed/TweenMax.js",
        "./src/uncompressed/TimelineLite.js",
        "./src/uncompressed/jquery.gsap.js"
      ]
    },
    "slick-carousel": {
      "main": [
        "./slick/slick.min.js",
        "./slick/slick.css",
        "./slick/slick-theme.css"
      ]
    },
    "waypoints": {
      "main": [
        "./lib/jquery.waypoints.min.js"
      ]
    }
  }
}
You would need to define them in the Gulp file build uglify task.
