API

const listDirectories = require('list-directories');

listDirectories(dir)

dir: string Buffer URL (directory path)
options: Object (readdir-sorted options)
Return: Promise<Set<string>>

The promise will be fulfilled with a Set of strings — absolute paths of all directories included in the given directory.

Options are directly passed to the underlying readdir-sorted to control the order of results.

listDirectories('/dirs').then(files => {
  const iterator = files[Symbol.iterator];
 
  iterator.next().value; //=> '/dirs/10'
  iterator.next().value; //=> '/dirs/2a'
  iterator.next().value; //=> '/dirs/2A'
});
 
listDirectories('/dirs', {
  numeric: true,
  caseFirst: 'upper'
}).then(files => {
  const iterator = files[Symbol.iterator];
 
  iterator.next().value; //=> '/dirs/2A'
  iterator.next().value; //=> '/dirs/2a'
  iterator.next().value; //=> '/dirs/10'
});
