fakerator was inspired by and has used data definitions from Marak's faker.js library
If you like my work, please donate. Thank you!
$ bower install fakerator$ npm install fakeratorDownload the package and use the dist/fakerator.js or the dist/fakerator.min.js file in your project.

<script>
var fakerator = Fakerator();
var name = fakerator.names.name();
var user = fakerator.entity.user();
</script>var Fakerator = require("fakerator");
var fakerator = Fakerator("de-DE");
var name = fakerator.names.name();
// Result: 'Dr. Marcus Drechsler'Shortly
var fakerator = require("fakerator")("hu-HU");
var name = fakerator.names.name();
// Result: 'Fülöp Magdolna'Or load a specific locale
var fakerator = require("fakerator/locales/de-DE")();
var name = fakerator.names.name();
// Result: 'Dr. Marcus Drechsler'The library uses the Mersenne Twister pseudorandom number generator, so set seed value, if you want to get a repeatable random sequence:
fakerator.seed(5567832);Generate random values or select a random element from array.

The library supports localizations. You can set the locale code in constructor.
// Use default (English) localization
var fakerator = Fakerator();
console.log(fakerator.names.name());
// Floyd Corkery // Use german
var fakerator = Fakerator("de-DE");
console.log(fakerator.names.name());
// Hassan vom Kumbernuss // Use russian
var fakerator = Fakerator("ru-RU");
console.log(fakerator.names.name());
// Альберт Валентинович АрхиповIn production, you can load only a specific locale:
// Use french
var fakeratorFR = require("fakerator/locales/fr-FR")();
console.log(fakeratorFR.names.name());

}You can generate array of items with times and utimes (unique) functions.
First parameter is the generator function. Second is the length of array.
You can pass further parameters, they will be passed to the generator function.
// Generate 3 names
fakerator.times(fakerator.names.name, 3);
// [ "Ross Hansen", "Thomas Pfeffer", "Alexis Hauck I" ]
// Generate 5 username with populate where first name must be 'John'
fakerator.times(fakerator.populate, 5, "#{internet.userName}", "John");
// [ 'john.langosh8341', 'john12', 'john.howe5075', 'john_jerde', 'john.grant9923' ]
// Generate 5 number from 1 to 10
fakerator.times(fakerator.random.number, 5, 1, 10);
// [ 10, 8, 1, 8, 5 ]
// Note: 8 is twice!
// Generator 5 UNIQUE number from 1 to 10
fakerator.utimes(fakerator.random.number, 5, 1, 10);
// [ 10, 2, 9, 6, 1 ]
// Note: every number is unique!You can also generate fake data with templates:
fakerator.populate("#{names.name}")
// Ross Hansenfakerator.populate("#{address.street}")
// 0662 Ferry Drivefakerator.populate("Hi, my name is #{names.name}. I was born in #{address.city}, #{address.country}. I am #{date.age} years old.")
// Hi, my name is Mrs. Rufus Shanahan. I was born in Hilpertton, Denmark. I am 44 years old.The populate replace # symbol to a random number and ? symbol to a random letter.
fakerator.populate("#{names.firstName}-###-???")
