## Hosted API Microservice

- Supports all Faker API Methods
- Full-Featured Microservice
- Hosted by [hook.io](http://hook.io)
```bash
curl http://faker.hook.io?property=name.findName&locale=de
```
## Usage
### Browser
<script src = "faker.js" type = "text/javascript"></script>
<script>
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
</script>
### 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()
faker.js contains a super useful generator method `Faker.fake` for combining faker API methods using a mustache string format.
**Example:**
``` js
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()`

## Localization
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:
```js
// sets locale to de
faker.locale = "de";
```
* az
* cz
* de
* de_AT
* de_CH
* en
* en_AU
* en_BORK
* en_CA
* en_GB
* en_IE
* en_IND
* en_US
* en_au_ocker
* es
* es_MX
* fa
* fr
* fr_CA
* ge
* id_ID
* it
* ja
* ko
* nb_NO
* nep
* nl
* pl
* pt_BR
* ru
* sk
* sv
* tr
* uk
* vi
* zh_CN
* zh_TW
### Individual Localization Packages
As of vesion `v3.0.0` 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.
```js
// loads only de locale
var faker = require('faker/locale/de');
```
## Setting a randomness seed
If you want consistent results, you can set your own seed:
```js
faker.seed(123);
var firstRandom = faker.random.number();
// Setting the seed again resets the sequence.
faker.seed(123);
var secondRandom = faker.random.number();
console.log(firstRandom === secondRandom);
```
## Tests
npm install .
make test

```
npm run-script doc
```
## Version Release Schedule
faker.js is a popular project used by many organizations and individuals in production settings. Major and Minor version releases are generally on a monthly schedule. Bugs fixes are addressed by severity and fixed as soon as possible.
If you require the absolute latest version of `faker.js` the `master` branch @ http://github.com/marak/faker.js/ should always be up to date and working.
