Description

This module is designed to sort absolute directory paths. Order is determined by:

• Path depth
  Shallower paths come first.
• Path component types (file or directory)
  Files take precedence over directories, e.g. D:\hello.txt always comes before D:\abc\a.jpg, regardless of alphabetical order.
• Lexical comparison
  If two path components are of the same type, they are compared lexically, in a case-insensitive fashion.

Note: path component type is determined by the trailing separator, e.g.:

path	detected types
/a/b	dir, file
/a/b/	dir, dir
D:\cat.jpeg	dir, file
D:\music\	dir, dir

Install

Node.js
npm i sort-paths --save
var sortPaths = require('sort-paths');

Browser
Include either the full or minified version from /browser, and use sortPaths() globally.
<script src="path/to/sort-paths.min.js"></script>

Examples

sortPaths(
    [
        '/b/cat.png',
        '/b/dog.jpeg',
        '/a/b/e.txt',
        '/b/',
        '/a/x.txt'
    ],
    '/'
);
 
/*
    /a/x.txt
    /a/b/e.txt
    /b/
    /b/cat.png
    /b/dog.jpeg
*/

sortPaths(
    [
        'E:\\',
        'D:\\music\\',
        'D:\\',
        'D:\\music\\song.mp3'
    ],
    '\\'
);
 
/*
    D:\\
    D:\\music\\
    D:\\music\\song.mp3
    E:\\
*/

    ],
    function (item) { return item.path; },
    '/'
