ReturnDirectJsonResponseRector

Find another rule

Instead of creating JsonResponse, setting items and data, return it directly at once to improve readability

 use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

 class SomeController extends AbstractController
 {
     public function index()
     {
-        $response = new JsonResponse();
-        $response->setData(['key' => 'value']);
-
-        return $response;
+        return new JsonResponse(['key' => 'value']);
     }
 }

Configure your rector.php:

<?php

use Rector\Config\RectorConfig;
use Rector\Symfony\CodeQuality\Rector\ClassMethod\ReturnDirectJsonResponseRector;

return RectorConfig::configure()
    ->withRules([
        ReturnDirectJsonResponseRector::class,
    ]);
