# FractalTransformerView plugin for CakePHP
This plugin is a thin wrapper for `JsonView` that allows using [Fractal transformers][fractal-transformer] for your API output. What is [Fractal][fractal]?
> Fractal provides a presentation and transformation layer for complex data output, the like found in RESTful APIs, and works really well with JSON. Think of this as a view layer for your JSON/YAML/etc.
> When building an API it is common for people to just grab stuff from the database and pass it to json_encode(). This might be passable for “trivial” APIs but if they are in use by the public, or used by mobile applications then this will quickly lead to inconsistent output.
## Requirements
- CakePHP 5.x (use ~1.0 for CakePHP 3.x, ~2.0 for CakePHP 4.x)
## Installation
You can install this plugin into your CakePHP application using [Composer][composer].
```bash
composer require andrej-griniuk/cakephp-fractal-transformer-view
```
## Usage
To enable the plugin set `FractalTransformerView.FractalTransformer` class name for viewBuilder. Then you just do what you would normally do in your [data views](http://book.cakephp.org/4/en/views/json-and-xml-views.html) - specify which view vars you want to get serialized by setting `serialize` view builder option. E.g.:
```php
namespace App\Controller;
class ArticlesController extends AppController
{
public function initialize(): void
{
parent::initialize();
$this->loadComponent('RequestHandler');
$this->viewBuilder()->setClassName('FractalTransformerView.FractalTransformer');
}
public function index()
{
// Set the view vars that have to be serialized.
$this->set('articles', $this->paginate());
// Specify which view vars JsonView should serialize.
$this->viewBuilder()->setOption('serialize', ['articles']);
}
}
```
The view will look for transformer class starting with entity name. E.g.:
```php
namespace App\Model\Transformer;
use App\Model\Entity\Article;
use League\Fractal\TransformerAbstract;
class ArticleTransformer extends TransformerAbstract
{
/**
* Creates a response item for each instance
*
* @param Article $article post entity
* @return array transformed post
*/
public function transform(Article $article)
{
return [
'title' => $article->get('title')
];
}
}
```
If transformer class not found the variable is serialized the normal way.
Custom transformer class name can be set by defining `transformer` view builder option:
```php
$this->viewBuilder()->setOption('transform', ['articles' => '\App\Model\Transformer\CustomArticleTransformer']);
```
You can also define if you don't want to use transformer for certain variables:
```php
$this->viewBuilder()->setOption('transform', ['articles' => false]);
```
You can set a custom serializer (class name or object) via `serializer` view builder option:
```php
$this->viewBuilder()->setOption('serializer', new CustomSerializer());
```
## Baking Transformers
To bake transformers you must include the plugin in your src/Application.php file. Add the following to your bootstrap method:
```php
$this->addPlugin('FractalTransformerView');
```
You must also have the [cakephp/bake](https://packagist.org/packages/cakephp/bake) composer package installed.
You can now run `bin/cake bake transformer YOUR_MODEL` to create transformers.
