randino for JavaScript

📘 randino.cdget.com

Every option and every example, with JavaScript picked in the sidebar. This README is just the quick start.

---

randino generates random person names, nicknames, words and sentences in the language you ask for.

• Person names read like names people carry: Emma Clover, Jack Reeves, each with its English pronunciation. 9 languages.
• Nicknames are handles for a game or a website: MistyOwl, CraneVoyage, RustyBoot. Built from everyday words across twenty-nine themes, and never from person names.
• Words are those themes on their own: randWord, plus randAnimal, randFood and twenty-seven more.
• Sentences are whole statements in the language's own grammar, from randSentence. The verb decides what can stand beside it, so the words of one sentence belong together.
• Decorators attach something to a string you already have: randSuffix, randPrefix and randModifier.
• One options object per generator, every option optional: randName() on its own works.
• No runtime dependencies. ESM, typed, and it runs in Node and in the browser alike.

This is the JavaScript package. The Dart package and the Python package are the other two, and all three generate from the same datasets under the same rules. They version independently, so the numbers on npm, pub.dev and PyPI will not always agree.

Install

npm install randino

Requires Node.js 18 or newer, or any browser. The package ships ESM with type declarations and pulls nothing in behind it.

Words

The pools the nicknames are built from, on their own. Twenty-nine themes, nine languages, and a function per theme.

import { randAnimal, randFood, randWord, wordLengthRange } from 'randino';

randWord({ language: 'en', theme: 'animal', count: 3 });
// ['Otter', 'Falcon', 'Lynx']

randAnimal({ language: 'en', count: 2 }); // ['Turtle', 'Crane']
randFood({ language: 'en', count: 2 }); // ['Dumpling', 'Cocoa']

// [{ word: 'Cedar', language: 'en', theme: 'plant' }]

wordLengthRange('en'); // [3, 11]

Option	Type	Default
language	'all' or a language code	'all'
theme	'all' or a theme name	'all'

startsWith	string	—
unique	boolean	false
output	'value' | 'detail'	'value'

One function per theme: randAnimal, randObject, randNature, randPlant, randGem, randConcept, randMyth, randJob, randMusic, randPlace, randFood, randSport, randVehicle, randProduct, randColor, randFinance, randTech, randWeather, randSpace, randTime, randEmotion, randBody, randClothing, randTool, randDrink. Each is randWord with the theme already chosen.

Sentences

Whole statements, written the way the language writes them. The nouns are the same pools the words and nicknames come from, and what a sentence adds is the grammar: a verb that states what can do it and what it can be done to, and the shapes each language allows.

import { randSentence, sentenceLengthRange } from 'randino';

randSentence({ language: 'en', count: 3 });
// ['The brave lion runs quietly.', 'The otter swims in the cove.', 'The sky is blue.']

randSentence({ language: 'ko', count: 2 });
// ['검은 고양이가 숲에서 잠잔다.', '여우가 사과를 먹는다.']

randSentence({ language: 'en', shape: 'simple' }); // ['The gondola passes.']
randSentence({ language: 'en', include: ['brave', 'lion'] });
// ['The brave lion yawns quietly.']

randSentence({ language: 'ko', output: 'detail' });
// [{
//   sentence: '검은 고양이가 숲에서 잠잔다.',
//   phrases: ['검은 고양이', '숲', '잠잔다'],
//   slots: ['subject', 'place', 'verb'],
//   language: 'ko',
//   theme: 'animal'
// }]

sentenceLengthRange('en'); // [12, 92]

Option	Type	Default
language	'all' or a language code	'all'
theme	'all' or a theme name	'all'
shape	'all' | 'simple' | 'detailed' | 'complex'	'all'
slots	'all' | 'none' or one or more SentenceSlot	'all'
include	string or string[]	—
type	'all' or one or more SentenceType	drawn
quote	'double' | 'single'	—
style	SentenceStyle	drawn
sentences	number	1
includeName	boolean	drawn
count	number	1
realism	RandRealism	'real'
vocabulary	RandVocabulary	'common'
minLength / maxLength	number	language
startsWith	string	—
unique	boolean	false
output	'value' | 'detail'	'value'

slots names the parts a shape may carry beside its subject: object, place, time, manner, state, quantity, money, date, clock, or 'none' for a subject and its predicate alone. A language declares its own shapes, so German has no object and Russian no place, because both would mark those with a case their nouns have to change for. Asking for one falls back to the closest shape the language does have.

include puts words you name into every sentence. A word the pools hold goes in the phrase it belongs to, and a word from anywhere else is used as a noun.

type is what the sentence does: a statement, a question, an exclamation, a line that trails off, or one somebody says or thinks. style is the speech level, which Korean writes four of. sentences puts up to ten of them in one string, about one subject. includeName puts a generated person's name where a person can stand. Left out, the three of them are drawn per result.

Decorators

randSuffix, randPrefix and randModifier attach something to a string you already have, rather than generating one. They take anything, not just this library's output, which is why none of them is an option on a generator. Each of them also works with no value at all, handing back the thing it would have attached.

import { randNickname, randPrefix, randSuffix } from 'randino';

randSuffix('MistyOwl'); // 'MistyOwl_nVtRC'
randSuffix(randNickname({ language: 'en', count: 2 }));
// ['RoundSeason_RVBnC', 'RowdyDusk_dwtu5']

randPrefix('order-4021', { length: 4, separator: '-' }); // 'k3Rm-order-4021'
randSuffix('MistyOwl', { length: 8, charset: '0123456789' }); // 'MistyOwl_40218836'
randSuffix(); // 'nVtRC' — the token on its own

Option	Type	Default
length	number	5
separator	string	'_'
charset	string	built-in

A fresh token per value, never one for the batch. The default charset leaves out 0O1lI, because these end up in names people read aloud and type back in.

randModifier attaches a word instead of a token, in front of any string:

import { randAnimal, randModifier } from 'randino';

randModifier('Owl'); // 'MistyOwl'
randModifier('Owl', { separator: ' ' }); // 'Misty Owl'
randModifier('Owl', { kind: 'action' }); // 'CountingOwl'
randModifier(); // 'Misty'

randModifier(randAnimal({ language: 'en', count: 2 }));
// ['TwinklingLynx', 'OnyxCrane']

Option	Type	Default
language	WordLanguageOption	script
realism	RandRealism	'real'
kind	ModifierKind | 'all'	'all'
separator	string	language

With no language, the script of the value picks one, so '고양이' is never handed an English modifier.

Helpers and constants

import {
	nameLengthRange,
	nameSupportsMiddleName,
	nameSupportsRoman,
	nicknameLengthRange,
	sentenceLengthRange,
	wordLengthRange,
	NAME_LANGUAGES,
	WORD_THEMES
} from 'randino';

nameLengthRange('ko'); // [2, 3]
nameLengthRange('en', true, true); // [11, 32]
nameSupportsMiddleName('ko'); // false
nameSupportsRoman('en'); // false
nicknameLengthRange('ko'); // [1, 13]
sentenceLengthRange('ko'); // [5, 43]
wordLengthRange('ko'); // [1, 4]

NAME_LANGUAGES, WORD_LANGUAGES and WORD_THEMES list what the generators accept; RAND_COUNT_MAX, RAND_LENGTH_MIN / _MAX, RAND_SENTENCE_LENGTH_MAX, AFFIX_LENGTH_DEFAULT / _MAX, AFFIX_SEPARATOR_DEFAULT and AFFIX_CHARSET are the bounds and defaults every option is clamped to.

Development

npm install
npm run test      # tsc, then node --test over test/**
npm run build     # format, tsc, minify
npm run lint

The tests import from dist/, so they need a build. npm run test does that first.
