Template

Copy<?php

namespace App\Service\Bll;

use App\Service\Api\Api<Feature>;
use StarterKit\Model\ApiResult;
use StarterKit\Service\Bll\HelperService;

class <Feature>Service
{
    public function __construct(
        private readonly HelperService $helper,
        private readonly Api<Feature>  $api,
    ) {
        $this->helper->logDebug("[App] - Service - <Feature>Service - Load");
    }

    public function read(string $key): ApiResult
    {
        $this->helper->logDebug("[App] - Service - <Feature>Service - Read");

        return $this->api->read($this->helper->getLanguage(), $key);
    }

    public function update(string $key, array $data): ApiResult
    {
        $this->helper->logDebug("[App] - Service - <Feature>Service - Update");

        return $this->api->update($this->helper->getLanguage(), $key, $data);
    }
}

Key Rules

1. Constructor injection (unlike Route controllers)
2. Inject HelperService for language and logging
3. Use $this->helper->getLanguage() for API calls
4. Return ApiResult
5. Log method calls

---

Checklist

• HelperService injected
• Api service(s) injected
• Methods use $this->helper->getLanguage()
• Debug logging at method entry
• Returns ApiResult
