node-muid

muid.js

A JavaScript library for converting between UUIDs and Process Street micro UUIDs ("Muids").

Muids are URL-safe and take up 31.25% less characters than UUIDs while encoding the same amount of information.bower.json

Installation

In a browser:

<script src="muid.js"></script>

Via bower:

bower install muid.js

Notes

This method will provides a global Muid object. That means that once you include it, you can use it like this:

var uuid = '19ab5c32-038b-4ba3-841f-b427f65e1943';
var muid = Muid.fromUuid(uuid);
// = 'hB-0J_ZeGUMZq1wyA4tLow'

The fromUuid is case-insensitive (i.e. you can pass 19ab5c32-038b-4ba3-841f-b427f65e1943 or 19AB5C32-038B-4BA3-841F-B427F65E1943 and dash-insensitive (i.e. 19ab5c32-038b-4ba3-841f-b427f65e1943 or 19ab5c32038b4ba3841fb427f65e1943 are treated the same).

A toUuid function is also provided for converting a Muid to a UUID:

var muid = 'hB-0J_ZeGUMZq1wyA4tLow';
var uuid = Muid.toUuid(muid);
// = '19ab5c32-038b-4ba3-841f-b427f65e1943'

Why not just use UUIDs?

The motivation behind Muids is that they take up 22 characters instead of 32. This leads to Muids taking up 31.25% less space in URLs than UUIDs.
