Usage

Browser

  var randomName = faker.name.findName(); // Caitlyn Kerluke
  var randomEmail = faker.internet.email(); // Rusty@arne.info
  var randomCard = faker.helpers.createCard(); // random contact card containing many properties

Node.js

var faker = require('faker');

var randomName = faker.name.findName(); // Rowan Nikolaus
var randomEmail = faker.internet.email(); // Kassandra.Haley@erich.biz
var randomCard = faker.helpers.createCard(); // random contact card containing many properties

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('{{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()
