minifaker

minifaker

Generate fake data.
An alternative to faker.js with both esm and cjs syntax https://github.com/Marak/faker.js

NPM

npm i minifaker

Supported locales

en | fr, fr-CA | es

Why

faker.js is big, does not support tree shaking and is not in Typescript https://github.com/Marak/faker.js/issues/785

On 2021/01/05, Marak deleted fakerjs from npm and github.

Why not create a pull request to faker.js?

Supporting ES6 modules for faker.js would need a big restructure change.

Right now, I just need a couple of functions and it's faster to create a new package mirroring functions without having to do a lot of refactoring. However, importing the entire package will take work and time, but at least I can start using it without having to finish it.

I also want to use Typescript and introduce new functions.

Duplicates

I've notice that faker locales have duplicate words :S.
I'll try fix the duplicates when importing locale files to reduce size as much as possible.

Replacing old functions with new powerful packages instead

• nanoid, uuid

Example / usage

Using functions

// You can either import minifaker completely 
// or import the functions you need
import minifaker, { arrayElement } from 'minifaker'
// const minifaker = require('minifaker')

minifaker.number()
arrayElement(['one', 'two', 'three'])

Using locale dependent functions

import minifaker, { cityName } from 'minifaker'
// There is no default locale import (not even `english`)
import 'minifaker/locales/en' // the first locale import is set as default
import 'minifaker/locales/fr'

minifaker.firstName({ gender: 'female' }) // female name in english
cityName({ locale: 'fr' }) // french city name

Generating a list of 50 english names

import { array, name } from 'minifaker'
import 'minifaker/locales/en'

array(50, () => name())

Generating english words

import { word } from 'minifaker'
import 'minifaker/locales/en'

word() // Can be an adjective, adverb, conjunction, interjection, noun, preposition, verb
word({ filter: (word) => word.length > 5 }) // Word with at least 5 characters
word({ type: 'noun' }) // A noun

Word types

verb,preposition,noun, interjection, conjunction, adverb, adjective

Direct access to more performant/popular packages

import { nanoId, uuid, nonsecure } from 'minifaker'

nanoId.nanoid() // nanoid - https://github.com/ai/nanoid
nonsecure.nanoid() // nanoid/non-secure - https://github.com/ai/nanoid/blob/main/non-secure/index.js
uuid.v4() // uuid - https://github.com/uuidjs/uuid
