Synopsis

Uses the uuid module to produce an rfc4122 v4 compliant uuid and then encodes it using a 64-char alphabet (by default includes upper, lower letters, numbers, -, _) to encode the uuid in a shortened (22 characters - instead of 32 hex) but still url friendly string.

The module is just a few lines of code

var CHARS = '.PYFGCRLAOEUIDHTNSQJKXBMWVZ_pyfgcrlaoeuidhtnsqjkxbmwvz1234567890';
module.exports = function (chars) {
    var uuid = require('uuid');
    var d64 = require('d64')(chars||CHARS);
    return d64.encode(uuid.v4(null,new Array(16),0))
}

#Description Using this module:

> var uuid = require('uuid-encoded');
> console.log(uuid());
'xkfA7KJ1NEY7oFH21vEi7-'
> console.log(uuid());
'qOloinw5JJRBf-OPJIqrgx'
> console.log(uuid());
'wVeh8at4SB5UFnMQ69awQ-'
> // use an alphabet that uses . instead of -
> uuid('.PYFGCRLAOEUIDHTNSQJKXBMWVZ_pyfgcrlaoeuidhtnsqjkxbmwvz1234567890')
'D7a1L0.PSvQo_DIjccTKuc'

Installation

Installing the module

npm install uuid-encoded

Note

The uuid author is pointing out that these uuids are "cryptographically strong", ie unguessable strings. Still keep in mind that RFC4122 points against the use of this format for trully "unguessable" keys. image
