Random Fixture Data

Adapted from casual's fake data generator. This version creates mixed-case methods that pass jshint tests when camelcase is set to true. New methods are documented below...

NPM version Build Status Dependency Status

Installation

npm install random-fixture-data --save-dev

Usage

const data = require('random-fixture-data');

// Generate random sentence
// You don't need function call operator here
// because most of generators use properties mechanism
let sentence = data.sentence;

// Generate random city name
let city = data.city;

// Define custom generator
data.define('point', function() {
	return {
		x: Math.random(),
		y: Math.random()
	};
});

// Generate random point
let point = data.point;

// And so on..

Random Fixture Data uses javascript properties for common generators so you don't need to use function call operator

Define custom generators

casual.define('user', function() {
	return {
		email: casual.email,
		firstname: casual.first_name,
		lastname: casual.last_name,
		password: casual.password
	};
});

// Generate object with randomly generated fields
let user = casual.user;

If you want to pass some params to your generator:

casual.define('profile', function(type) {
	return {
		title: casual.title,
		description: casual.description,
		type: type || 'private'
	};
});

// Generate object with random data
let profile = casual.profile('public');

NOTE: if getter function has non-empty arguments list then generator should be called as function casual.profile('public'), otherwise it should be accessed as property casual.profile.

Localization

You can get localized version of casual generator:

let casual = require('casual').ru_RU;
casual.street; // 'Бухарестская'

Default locale is en_US.

See src/providers/{{locale}} for more details about available locales and locale specific generators.

If you don't find necessary locale, please create an issue or just add it :)

Helpers

random_element (randomElement)

Get random array element

let item = casual.random_element(['ball', 'clock', 'table']);

random_value (randomValue)

Extract random object value

let val = casual.random_value({ a: 1, b: 3, c: 42 });
// val will be equal 1 or 3 or 42

random_key (randomKey)

Extract random object key

let val = casual.random_key({ a: 1, b: 3, c: 42 });
// val will be equal 'a' or 'b' or 'c'

populate

Replace placeholders with generators results

casual.populate('{{email}} {{first_name}}');
// 'Dallin.Konopelski@yahoo.com Lyla'

populate_one_of

Pick random element from given array and populate it

let formats = ['{{first_name}}', '{{last_name}} {{city}}'];
casual.populate_one_of(formats);

// Same as

casual.populate(casual.random_element(formats));

numerify

Replace all # in string with digits

let format = '(##)-00-###-##';
casual.numerify(format); // '(10)-00-843-32'

define

See custom generators

register_provider

Register generators provider

let words = ['flexible', 'great', 'ok', 'good'];
let doge_provider = {
	such: function() {
		return 'such ' + casual.random_element(words);
	},

	doge_phrase: function() {
		return 'wow ' + provider.such();
	}
};

casual.register_provider(doge_provider);

casual.such;        // 'such good'
casual.doge_phrase; // 'wow such flexible'

Seeding

If you want to use a specific seed in order to get a repeatable random sequence:

casual.seed(123);

It uses Mersenne Twister pseudorandom number generator in core.

Generators functions

If you want to pass generator as a callback somewhere or just hate properties you always can access generator function at casual._{generator}

// Generate value using function
let title = casual._title();
// Same as
let title = casual.title;

// Pass generator as callback
let array_of = function(times, generator) {
	let result = [];

	for (let i = 0; i < times; ++i) {
		result.push(generator());
	}

	return result;
};

// Will generate array of five random timestamps
let array_of_timestamps = array_of(5, casual._unix_time);

Or you can get functional version of casual generator:

let casual = require('casual').functions();

// Generate title
casual.title();

// Generate timestamp
casual.unix_time();

View providers output cli

There is a simple cli util which could be used to view/debug providers output:

# Will render table with columns [generator_name, result] for all providers
node utils/show.js

 # Will render table with columns [generator_name, result] only for person provider
node utils/show.js person
