 # Response using Transformer
 
+You'll need to install [laravel-datatables-fractal package](https://github.com/yajra/laravel-datatables-fractal) if you haven't already.
+
 When using tranformer, all response manipulations must be done via transformer.
 Thus `addColumn`, `editColumn`, `removeColumn`, `setRowAttr`, `setClassAttr`, etc... should be avoided when using fractal.
 
+## Closure
+
+You can pass a closure which will receive an item of the result collection and should return an array.
+
 ```php
 use DataTables;
-use App\Transformers\UserTransformer;
+use App\User;
+
+Route::get('user-data', function() {
+    $model = User::query();
+
+    return DataTables::eloquent($model)
+                ->setTransformer(function($item){
+                    return [
+                        'id'         => (int) $user->id,
+                        'name'       => $user->name,
+                        'email'      => $user->email,
+                        'created_at' => (string) $user->created_at,
+                        'updated_at' => (string) $user->updated_at,
+                    ];
+                })
+                ->toJson();
+});
+```
+
+Thus you can make use of Laravel API Resource.
+
+```php
+use DataTables;
+use App\User;
+use App\Http\Resources\UserResource;
 
 Route::get('user-data', function() {
-	$model = App\User::query();
+    $model = User::query();
 
-	return DataTables::eloquent($model)
-				->setTransformer(new UserTransformer)
-				->toJson();
+    return DataTables::eloquent($model)
+                ->setTransformer(function($item){
+                    return UserResource::make($item)->resolve();
+                })
+                ->toJson();
 });
 ```
 
-## Creating Transformer
+
+## Transformer
+
+You can use Transformer class.
+
+```php
+use DataTables;
+use App\Transformers\UserTransformer;
+
+Route::get('user-data', function() {
+    $model = App\User::query();
+
+    return DataTables::eloquent($model)
+                ->setTransformer(new UserTransformer)
+                ->toJson();
+});
+```
