    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";
    
    • 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.

    // 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

    Building faker.js

    faker uses gulp to automate it's 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 updateds to ReadMe.md should be perfomed 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 branch @ http://github.com/marak/faker.js/ should always be up to date and working.
