minifaker

minifaker

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

NPM

npm i minifaker

Why

faker.js is too big and it's not currently supporting tree shaking. https://github.com/Marak/faker.js/issues/785

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.

Better function alternatives

I will deprecate functions with better alternatives.

• use npm i nanoid to generate string ID
• use npm i lorem-ipsum to generate lorem words

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.

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

minifaker.firstName({ gender: 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/dist/locales/en'

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