@marianmeres/random-human-readable

Simple utility function to generate random but human-readable strings. The internal English words dictionary has ~1500 nouns, ~250 adjectives and ~130 colors, which makes — with default options — over 48 billion unique choices.

Should you worry about collisions, you can grow the count of possible choices by orders of magnitude by simply increasing the adjCount/colorsCount/nounsCount/syllablesCount options and/or setting the randomizeCase flag.

Installation

# npm
npm install @marianmeres/random-human-readable

# jsr
deno add @marianmeres/random-human-readable

Main usage

import { getRandomHumanReadable } from '@marianmeres/random-human-readable';

// All options are optional, and the generation order is always:
// 1. adjectives, 2. colors, 3. nouns, 4. syllables, (5. digits, 6. special chars)
getRandomHumanReadable({
	// number of adjectives to generate
	adjCount: 1,
	// number of colors to generate
	colorsCount: 1,
	// number of nouns to generate
	nounsCount: 2,
	// number of (nonsense) syllables to generate
	syllablesCount: 0,
	// if true, will RanDOmiZe case on generated output
	randomizeCase: false,
	// string to join the generated words with
	// (use explicit `false` to disable joining and return as array of words)
	joinWith: '-',

	// Since many password validators require digits and/or special chars (and this tool
	// can be used as a password generator), these are also supported, although they
	// are not really human-readable (in this context)
	digitsCount: 0,
	specialCharsCount: 0,
});

Example results (with default options):

fit-transparent-mouse-phrase
massive-navy-wood-joint
unkempt-cadetblue-hand-branch
incalculable-brown-quality-tank
chubby-aquamarine-year-flower
wooden-springgreen-profit-personal
prickly-darkblue-incident-schedule
refined-blue-reason-policy
wide-white-contract-transition
whispering-burlywood-ring-pizza

Or, if you're feeling options-adventurous:

getRandomHumanReadable({
	adjCount: 5,
	syllablesCount: 4,
	randomizeCase: true,
	// other options will be inherited from the defaults if not provided
});

You may get something like this:

shRiLLing-helPLESs-Tiny-jollY-ScrawNy-KHAki-PRiEsT-ZIFuvACy
