Mnemonic id

Library to generate easy to remember, and sometimes entertaining, human readable ids.

createStoryId(); // -> awesome-chipmunk-banish-evil-rat

Partly inspired by Docker name generator and major mnemonic system.

Highlights

• Dictionary of approximate 150 nouns (animals), 200 verbs, 500 adjectives.
• Deterministic id size, with max word length of 10 for nouns, 8 for verbs and adjectives.
• Customizable id generation.
• TypeScript annotated API.
• Slim package size with no dependencies.

Install

$ npm install mnemonic-id

Usage

Import in either way that suits your environment:

import { createNameId } from 'mnemonic-id';
createNameId();

import * as mnemonicId from 'mnemonic-id';
mnemonicId.createNameId();

const mnemonicId = require('mnemonic-id');
mnemonicId.createNameId();

Then select one of the existing id formats:

/** "noun", ≈ 10^2 permutations, 10 max length */
createNounId(); // -> narwhal

/** "adj+noun", ≈ 10^5 permutations, 19 max length */
createNameId(); // -> hungry-hippo

/** "adj+adj+noun", ≈ 10^6 permutations, 28 max length */
createLongNameId(); // -> hot-splendid-duck

/** "adj+noun+id", ≈ 10^14 permutations, 26 max length */
createUniqueNameId(); // -> dull-dugong-QkCHmf

/** "verb+adj+noun", ≈ 10^6 permutations, 28 max length */
createQuestId(); // -> find-pretty-sheep

/** "adj+noun+verb+adj+noun", ≈ 10^12 permutations, 48 max length */
createStoryId(); // -> eloquent-beaver-quote-unknown-dinosaur

/** "adj+adj+noun+verb+adj+adj+noun", ≈ 10^17 permutations, 64 max length */
createLongStoryId(); // -> wicked-evil-eel-help-horrible-pretty-hamster

/** "number" of given length, length^10 - length^9 permutations */
createNumberId(10); // -> 6941634647  (= 10^10-10^9 permutations)

/** "id" of given length, = 40^length permutations */
createId(10); // -> uXOGTUiOoD  (= 40^10 ≈ 10^16 permutations)

Or customize your own:

createCustomId({
  adjectives: 2,
  subject: true,
  verb: true,
  object: true,
  numberSuffix: 4,
  idSuffix: 6,
  delimiter: '_',
  capitalize: true
}); // -> Talented_Bold_Pig_Hunt_Brawny_Supreme_Bumblebee_6343_VQ5EAZ

Most existing formats can also be customized:

createNameId({
  adjectives: 3, 
  capitalize: true
  delimiter: '',
}); // -> OrdinaryCuddlyLaughingSquid
