By default gulp stores files with it's relative paths. To copy all minified javascript files from bower_components to build folder without relative paths:
var flatten = require('gulp-flatten');
gulp.src('bower_components/**/*.min.js')
.pipe(flatten())
.pipe(gulp.dest('build/js'));Result will be list of all .min.js files inside build/js dir:
build
└── js
├── angular-route.min.js
├── angular-sanitize.min.js
├── angular.min.js
└── bootstrap.min.js
Type: String
Default: ''
