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
- ar
- cz
- de
- de_AT
- de_CH
- en
- en_AU
- en_AU_ocker
- en_BORK
- en_CA
- en_GB
- en_IE
- en_IND
- en_US
- en_ZA
- es
- es_MX
- fa
- fi
- fr
- fr_CA
- fr_CH
- ge
- id_ID
- it
- ja
- ko
- nb_NO
- nep
- nl
- nl_BE
- pl
- pt_BR
- pt_PT
- ro
- ru
- sk
- sv
- tr
- uk
- vi
- zh_CN
- zh_TW
Individual Localization Packages
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 i
npm t
You can view a code coverage report generated in coverage/lcov-report/index.html.
Building faker.js
faker uses gulp to automate its build process. Each build operation is a separate task which can be run independently.
Browser Bundle
npm run browser
Building JSDocs
JSDOC v3 HTML API documentation
npm run jsdoc
Building ReadMe
The ReadMe.md
file for faker.js
is automatically generated and should not be modified directly. All updates to ReadMe.md
should be performed in ./build/src/docs.md
and then the build script should be run.
npm run readme
Version Release Schedule
faker.js is a popular project used by many organizations and individuals in production settings. Major and Minor version releases are generally on a monthly schedule. Bugs fixes are addressed by severity and fixed as soon as possible.
If you require the absolute latest version of faker.js
the master
