<script src = "faker.js" type = "text/javascript"></script>
<script>
var randomName = faker.name.findName(); // Caitlyn Kerluke
var randomEmail = faker.internet.email(); // Rusty@arne.info
var randomCard = faker.helpers.createCard(); // random contact card containing many properties
</script>
var faker = require('faker');
var randomName = faker.name.findName(); // Rowan Nikolaus
var randomEmail = faker.internet.email(); // Kassandra.Haley@erich.biz
var randomCard = faker.helpers.createCard(); // random contact card containing many properties
API
Faker.fake()
faker.js contains a super useful generator method Faker.fake for combining faker API methods using a mustache string format.
Example:
console.log(faker.fake("{{name.lastName}}, {{name.firstName}} {{name.suffix}}"));
// outputs: "Marks, Dean Sr."
This will interpolate the format string with the value of methods name.lastName(), name.firstName(), and name.suffix()

Localization As of version v2.0.0 faker.js has support for multiple localities. The default language locale is set to English. Setting a new locale is simple:
// sets locale to de
faker.locale = "de";

Individual Localization Packages As of vesion v3.0.0 faker.js supports incremental loading of locales. By default, requiring faker will include all locale data. In a production environment, you may only want to include the locale data for a specific set of locales.
// loads only de locale
var faker = require('faker/locale/de');
Setting a randomness seed
If you want consistent results, you can set your own seed:
faker.seed(123);
var firstRandom = faker.random.number();
// Setting the seed again resets the sequence.
faker.seed(123);
var secondRandom = faker.random.number();
console.log(firstRandom === secondRandom);
Tests
npm install .
make test
