Generate massive amounts of fake data in the browser and node.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 (for unknown reasons).
In the interest of the community, it has been decided that faker.js will continue to be maintained here and all help in its development will be appreciated.

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()
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

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');If you want consistent results, you can set your own seed:
faker.seed(123);
var firstRandom = faker.datatype.number();
// Setting the seed again resets the sequence.
faker.seed(123);
var secondRandom = faker.datatype.number();
console.log(firstRandom === secondRandom);npm install .
npm run testYou can view a code coverage report generated in coverage/lcov-report/index.html.
faker uses gulp to automate its build process. Each build operation is a separate task which can be run independently.
npm run browserJSDOC v3 HTML API documentation
npm run jsdocThe 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.
