API

Faker.fake()

As of version v3.0.0 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(',  '));
// outputs: "Marks, Dean Sr."

This will interpolate the format string with the value of methods name.lastName(), name.firstName(), and name.suffix()

  • en
  • en_AU

Individual Localization Packages

As of vesion v3.0.0 faker.js supports incremental loading of locales.

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');
