Memorable UUID generator written in JS with up to 10.5 Billion possible combinations.

🏠 Homepage

Installation

npm install muuid --save

Usage

Code:

const muuid = require('muuid')

const muuids = muuid({
  quantity: 10, // Optional
  format: ['adjective', 'color', 'verb', 'noun', 'number'], // Optional
  duplicateReport: true, // Optional
  separator: ['-'] // Optional
})

console.info(muuids)

Outputs:

[
  'beautiful-midnight-blue-tiptoeing-fisher-65',
  'courageous-black-kissing-wren-29',
  'energetic-lavender-believing-moose-27',
  'lovely-steel-blue-fiending-axolotl-71',
  'determined-black-leading-angelfish-37',
  'glamorous-aquamarine-trotting-grasshopper-38',
  'blushing-magenta-boolin-camel-34',
  'bright-deep-pink-weaving-steer-23',
  'pleasant-rose-helping-macaque-42',
  'bewildered-goldenrod-crawling-coyote-93'
]

Using example.js

Simply examine and run the example.js file in your terminal to see how to use the library:

node example.js

Config Options

format An array of strings that determines how the muuid will be structured. The order of types is used when the id is generated. It can take the following format types:

['adjective', 'color', 'verb', 'noun', 'number']

quantity How many ids you want to batch generate at a single time.

duplicateReport Will output in console a simple report of duplicates.

separator An array of strings that will be used to separate the different parts of the muuid. If you supply more than one string in the array, the separator will be a random value for each part of the generated muuid. Defaults to ['-'] which will produce a result like the demo above.

Universal Uniqueness

Ok, you got me, technically this library does not produce Universally Unique memorable IDs as the name implies... When generating and using this tool to create IDs in your application, you should check their uniqueness against values you have already generated and stored. Also, due to the nature of this being a "memorable ID", I would avoid relying on this library to provide universal uniqueness across multiple different independent systems. I may attempt to modify the config options in the future to allow users to generate a more universally unique number or string to the output more akin to something you would see in a UUID.

In my testing, out of 5 million generated muuids, around 0.075% of them will not be unique, and that percentage slowly rises as you generate more. This is why it is critical to implement a duplicate check in your system before using any given outputted muuid.
