Update: Project Moved to faker

For the best interest of the community, I am merging this project with faker. See Discussion regarding this decision. The NPM package will be deprecated from now on and I will continue to contribute to faker.

Thank you.

Blaver - generate massive amounts of fake data in the browser and node.js

Blaver is a JavaScript library built on top of the Faker.JS library. It generates massive amounts of fake data in the browser and node.js.

Fake data is useful when building and testing our application. Blaver can generate fake data for various areas, including address, commerce, company, date, finance, image, random, or name.

What happened to the original faker.js?

This project was originally created and hosted at https://github.com/marak/Faker.js/ - however around 4th Jan, 2022 - the author decided to delete the repository along with the code, for unknown reasons.

Blaver is a fork of the original Faker.js library. The original library was created by Marak Squires in 2011. Blaver aims to maintain the original library's functionality and add new features.

You can also access unofficial Faker.js documentation at https://fakerjsdocs.netlify.com/

Blaver.fake()

Blaver contains a super useful generator method Blaver.fake for combining faker API methods using a mustache string format.

Example:

console.log(blaver.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

Blaver has support for multiple localities – ported directly from the orginal faker.js library (version v2.0.0).

The default language locale is set to English.

Setting a new locale is simple:

// sets locale to de
blaver.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
• he
• fa
• fi
• fr
• fr_CA
• fr_CH
• ge
• hy
• hr
• id_ID
• it
• ja
• ko
• mk
• nb_NO
• ne
• nl
• nl_BE
• pl
• pt_BR
• pt_PT
• ro
• ru
• sk
• sv
• tr
• uk
• vi
• zh_CN
• zh_TW

Individual Localization Packages

Blaver supports incremental loading of locales.

By default, requiring blaver 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 blaver = require('blaver/locale/de');

Setting a randomness seed

If you want consistent results, you can set your own seed:

blaver.seed(123);

var firstRandom = blaver.random.number();

// Setting the seed again resets the sequence.
blaver.seed(123);

var secondRandom = blaver.random.number();

console.log(firstRandom === secondRandom);

Tests

npm install .
make test

You can view a code coverage report generated in coverage/lcov-report/index.html.

Building Blaver

Blaver 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 blaver 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
