Usage
Browser
<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>
Node.js
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}}"));
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:
faker.locale = "de";
- az
- cz
- de
- de_AT
- de_CH
- en
- en_AU
- en_BORK
- en_CA
- en_GB
- en_IE
- en_IND
- en_US
- en_au_ocker
- es
- es_MX
- fa
- fr
- fr_CA
- ge
- id_ID
- it
- ja
- ko
- nb_NO
- nep
- nl
- pl
- pt_BR
- ru
- sk
- sv
- tr
- uk
- vi
- zh_CN
- zh_TW
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.
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();
faker.seed(123);
var secondRandom = faker.random.number();
console.log(firstRandom === secondRandom);
Tests
npm install .
make test
