### 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
* ar
* cz
* de
* de_AT
* de_CH
* en
* en_AU
* en_AU_ocker
* en_BORK
* en_CA
* en_GB
* en_IE
* en_IND
* en_US
* en_ZA
* es
* es_MX
* fa
* fi
* fr
* fr_CA
* fr_CH
* ge
* hy
* hr
* id_ID
* it
* ja
* ko
* nb_NO
* ne
* nl
* nl_BE
* pl
* pt_BR
* pt_PT
* ro
* ru
* sk
* sv
* tr
* uk
* vi
* zh_CN
* zh_TW
### Individual Localization Packages
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.datatype.number();
// Setting the seed again resets the sequence.
faker.seed(123);
var secondRandom = faker.datatype.number();
console.log(firstRandom === secondRandom);
```
## Tests
```shell
npm install .
make test
```
You can view a code coverage report generated in coverage/lcov-report/index.html.
## Building faker.js
faker uses [gulp](http://gulpjs.com/) to automate its build process. Each build operation is a separate task which can be run independently.
### Browser Bundle
```shell
npm run browser
```
### Building JSDocs
[JSDOC](https://jsdoc.app/) v3 HTML API documentation
```shell
npm run jsdoc
```
### Building ReadMe
The `ReadMe.md` file for `faker.js` is automatically generated and should not be modified directly. All updates to `ReadMe.md` should be performed in `./build/src/docs.md` and then the build script should be run.
```shell
npm run readme
```
## 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 @ should always be up to date and working.
