fakerator was inspired by and has used data definitions from [Marak's faker.js library](https://github.com/Marak/faker.js)

## Demo
[JSFiddle test page](https://jsfiddle.net/icebob/wngcbpkq/)

[Tonic demo](https://tonicdev.com/icebob/574c36fc8e1b8e130072a138)

## Install

### Bower

```bash
$ bower install fakerator
```

### NodeJS

```bash
$ npm install fakerator
```

### Manual
Download the package and use the `dist/fakerator.js` or the `dist/fakerator.min.js` file in your project.

## Usage
### Browser
```html

var fakerator = Fakerator();
var name = fakerator.names.name();
var user = fakerator.entity.user();

```

### NodeJS
```js
var Fakerator = require("fakerator");
var fakerator = Fakerator("de-DE");
var name = fakerator.names.name();
// Result: 'Dr. Marcus Drechsler'
```

Shortly
```js
var fakerator = require("fakerator")("hu-HU");
var name = fakerator.names.name();
// Result: 'Fülöp Magdolna'
```

Or load a specific locale

```js
var fakerator = require("fakerator/locales/de-DE")();
var name = fakerator.names.name();
// Result: 'Dr. Marcus Drechsler'
```

## Seeding
The library uses the [Mersenne Twister](http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html) pseudorandom number generator, so set seed value, if you want to get a repeatable random sequence:
```js
fakerator.seed(5567832);
```

## Random
Generate random values or select a random element from array.

Function | Description | Sample result
-----------------------------------| --------------------------- | -----------------------
`fakerator.random.boolean()` | Generate a boolean value | true
`fakerator.random.boolean(likelihoodPercent)` | Generate a boolean value based a likelihood value. | false
`fakerator.random.number(max)` | Generate a number value between 0 and max value | 87
`fakerator.random.number(min, max)` | Generate a number value between min and max | 54
`fakerator.random.digit()` | Generate a digit (0..9) | 5
`fakerator.random.letter()` | Generate a letter (a..z) | "h"
`fakerator.random.arrayElement(array)` | Give a random element from the array |
`fakerator.random.objectElement(obj)` | Give a random `{ key: value }` from the object

`fakerator.random.hex(length)` | Generate a hexadecimal number | "7950a0b9"
`fakerator.random.string(length)` | Generate a random string | "dulgecbhrsa"

## Localization
The library supports localizations. You can set the locale code in constructor.

### Usage
```js
// Use default (English) localization
var fakerator = Fakerator();
console.log(fakerator.names.name());
// Floyd Corkery
```

```js
// Use german
var fakerator = Fakerator("de-DE");
console.log(fakerator.names.name());
// Hassan vom Kumbernuss
```

```js
// Use russian
var fakerator = Fakerator("ru-RU");
console.log(fakerator.names.name());
// Альберт Валентинович Архипов
```

In production, you can load only a specific locale:

```js
// Use french
var fakeratorFR = require("fakerator/locales/fr-FR")();
console.log(fakeratorFR.names.name());
// Dufour Camille
```

## Times
You can generate array of items with `times` and `utimes` (unique) functions.
First parameter is the generator function. Second is the length of array.
> You can pass further parameters, they will be passed to the generator function.

### Usage
```js
// Generate 3 names
fakerator.times(fakerator.names.name, 3);
// [ "Ross Hansen", "Thomas Pfeffer", "Alexis Hauck I" ]

// Generate 5 username with populate where first name must be 'John'
fakerator.times(fakerator.populate, 5, "#{internet.userName}", "John");
// [ 'john.langosh8341', 'john12', 'john.howe5075', 'john_jerde', 'john.grant9923' ]

// Generate 5 number from 1 to 10
fakerator.times(fakerator.random.number, 5, 1, 10);
// [ 10, 8, 1, 8, 5 ]
// Note: 8 is twice!

// Generator 5 UNIQUE number from 1 to 10
fakerator.utimes(fakerator.random.number, 5, 1, 10);
// [ 10, 2, 9, 6, 1 ]
// Note: every number is unique!
```

## Templates
You can also generate fake data with templates:

```js
fakerator.populate("#{names.name}")
// Ross Hansen
```

```js
fakerator.populate("#{address.street}")
// 0662 Ferry Drive
```

```js
fakerator.populate("Hi, my name is #{names.name}. I was born in #{address.city}, #{address.country}. I am #{date.age} years old.")
// Hi, my name is Mrs. Rufus Shanahan. I was born in Hilpertton, Denmark. I am 44 years old.
```

### Replace symbols
The populate replace `#` symbol to a random number and `?` symbol to a random letter.
```js
fakerator.populate("#{names.firstName}-###-???")
// Mandy-802-oqs
```
