Returns a list of unique file extensions within the supplied directory.
npm install node-unique-extensions
Usage
javascript
var gux = require('node-unique-extensions');
var dirsToIgnore = ['node_modules'];
var extensions = gux({ path: '.', // These are optional exclusions: dirsToIgnore, includeDotFiles: true })
### Options
The following options are supported:
* `path`: the path to traverse for unique file extensions
* [`exclusions`]: an optional array of directory names to ignore
* [`includeDotFiles`]: Node doesn't consider dotfiles to have an extension, but this flag is useful
if you want to detect dotfiles like `.jshintrc`.
### Notes
* Currently synchronous.
* Excludes files without an extension (ex: Makefile)
