Laravel Spectrum

The Problem

// ❌ Traditional approach: Annotations everywhere
/**
 * @OA\Post(
 *     path="/api/users",
 *     @OA\RequestBody(
 *         @OA\JsonContent(
 *             @OA\Property(property="name", type="string"),
 *             @OA\Property(property="email", type="string", format="email"),
 *             // ... 50 more lines of annotations
 *         )
 *     ),
 *     @OA\Response(response="200", description="Success")
 * )
 */
public function store(StoreUserRequest $request) { ... }
