gulp-flatten 
Remove or replace relative path for files (gulp v3).
npm install gulp-flatten
Example source directory with bower compoments:

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: ''
Relative path for file.
Type: Number or Array of two numbers
If passed in as positive number, it will include the number of top-level parents in the output. Using this code:
gulp.src(['bower_components/**/*.css'])
.pipe(flatten({ includeParents: 1} ))
.pipe(gulp.dest('build/'));will create this structure (from sample directory tree above):
└── bootstrap
├── bootstrap-theme.css
├── bootstrap-theme.min.css
├── bootstrap.css
└── bootstrap.min.css
If passed in as negative number, it will include the number of bottom-level parents in the output. Using this code:
gulp.src(['bower_components/**/*.css'])
.pipe(flatten({ includeParents: -1} )) //or indludeParents: [0, 1]
.pipe(gulp.dest('build/'));will create this structure:
└── css
├── bootstrap-theme.css
├── bootstrap-theme.min.css
├── bootstrap.css
└── bootstrap.min.css
If passes as array of two numbers, both parents from top and bottom will be kept in resulting path of a file.
gulp.src(['bower_components/**/*.css'])
.pipe(flatten({ includeParents: [1, 1]} ))
.pipe(gulp.dest('build/'));will create this structure:
└── bootstrap
└── css
├── bootstrap-theme.css
├── bootstrap-theme.min.css
├── bootstrap.css
└── bootstrap.min.css
Type: Number or Array of two Numbers [begin, end]
This options applies Array.slice to the array of path elements and allows you
to receive a subsequences of the path.
gulp.src(['bower_components/**/*.css'])
.pipe(flatten({ subPath: [1, 1]} ))
.pipe(gulp.dest('build/'));This as an example would flatten top1/top2/bottom2/bottom1/file.txt to top2/file.txt.
[1, -1] would flatten top1/top2/bottom2/bottom1/file.txt to top2/bottom2/file.txt.
Please refer to the Array.slice documentation for a detailed description.
! If you're using both options.includeParents combined with options.subPath
please note that options.includeParents is applied first.
