human-readable-id-gen

human-readable-id-gen

Library for generating human-readable id strings.

Basic Usage

const { generateId } = require('human-readable-id-gen');

console.log(generateId());
// ex. Regina's required request

console.log(generateId());
// ex. Garrett's graceful giraffe

Custom Generators

The generateId function randomly pulls words from a default collection of nouns, adjectives, and names. To pull from a different set of words, you must use the IdGenerator class and its #generate method.

Using words in memory

Use the IdGenerator constructor with instances of WordCollection.

const { IdGenerator, WordCollection } = require('human-readable-id-gen');

let nouns = new WordCollection(['chair', 'tie', 'lamp']);
let adjectives = new WordCollection(['good', 'bad', 'ugly']);
let names = new WordCollection(['Tom', 'Dick', 'Harry']);

let idGenerator = new IdGenerator(nouns, adjectives, names);

console.log(idGenerator.generate());
// ex. Tom's ugly tie

Note that alliteration is not guaranteed if, for any word in the nouns collection, there isn't a word beginning with the same letter in both the adjectives and names collections, as above (adjectives has no words beginning with 't').

Loading from files

Use IdGenerator.load to load words from text files. These files should contain words separated by newlines.

const { IdGenerator } = require('human-readable-id-gen');

let idGenerator = IdGenerator.load(
	'path/to/nouns.txt',
	'path/to/adjectives.txt',
	'path/to/names.txt'
);

console.log(idGenerator.generate());
// ex. Leanna's logical laundry

Individual WordCollection instances can also be loaded from files:

const { IdGenerator, WordCollection } = require('human-readable-id-gen');

let nouns = WordCollection.load('path/to/nouns.txt');
let adjectives = new WordCollection(['good', 'bad', 'ugly']);
let names = new WordCollection(['Tom', 'Dick', 'Harry']);

let idGenerator = new IdGenerator(nouns, adjectives, names);

console.log(idGenerator.generate());
// ex. Harry's bad hair
