Kcy Laravel Package

Getting Started

Minimal Setup

1. Installation Add the package via Composer:

   composer require cayetanosoriano/kcy
   

   Ensure autoload is regenerated:

   composer dump-autoload
   

2. First Use Case Import the core class and initialize a client:

   use CayetanoSoriano\Kcy\KarmacracyClient;
   
   $client = new KarmacracyClient('your_api_key_here');
   

   Verify connectivity with a simple request:

   $response = $client->getKarmaPoints('user@example.com');
   

3. Where to Look First

   • src/KarmacracyClient.php: Core class for API interactions.
   • README.md: Basic usage examples (if expanded).
   • tests/: Test cases for expected behavior (if available).

Implementation Patterns

Core Workflows

1. Authentication Pass API keys via constructor or set dynamically:

   $client = new KarmacracyClient();
   $client->setApiKey('your_key_here');
   

2. CRUD Operations Follow PSR-0 conventions for method naming:

   // Create
   $client->createKarmaEntry($userId, $points);
   
   // Read
   $client->getKarmaPoints($userId);
   
   // Update
   $client->updateKarmaPoints($userId, $increment);
   
   // Delete (if supported)
   $client->deleteKarmaEntry($userId);
   

3. Error Handling Implement a wrapper for robust error handling:

   try {
       $response = $client->getKarmaPoints($userId);
   } catch (\CayetanoSoriano\Kcy\Exceptions\KarmaException $e) {
       Log::error("Karma API Error: " . $e->getMessage());
   }
   

4. Integration with Laravel Bind the client to the container in config/app.php:

   'bindings' => [
       CayetanoSoriano\Kcy\KarmacracyClient::class => function ($app) {
           return new KarmacracyClient(config('services.kcy.api_key'));
       },
   ];
   

   Use dependency injection in controllers:

   public function __construct(private KarmacracyClient $kcyClient) {}
   

5. Batch Processing If the API supports bulk operations, leverage collections:

   $userIds = [1, 2, 3];
   $client->batchUpdateKarmaPoints($userIds, 10); // Hypothetical method
   

Gotchas and Tips

Common Pitfalls

1. API Key Management

   • Gotcha: Hardcoding API keys in source files.
   • Fix: Use Laravel’s .env and config/services.php:

     KCY_API_KEY=your_key_here
     

     // config/services.php
     'kcy' => [
         'api_key' => env('KCY_API_KEY'),
     ],
     

2. Rate Limiting

   • Gotcha: Unhandled rate limits causing silent failures.
   • Tip: Implement exponential backoff in retries:

     use Symfony\Component\RateLimiter\RateLimiter;
     
     $limiter = new RateLimiter(10, 'minute');
     if (!$limiter->isAllowed()) {
         sleep($limiter->getWaitTime());
     }
     

3. PSR-0 Compliance

   • Gotcha: Assumptions about autoloading paths.
   • Tip: Verify composer.json autoload rules:

     "autoload": {
         "psr-0": {
             "CayetanoSoriano\\Kcy\\": "src/"
         }
     }
     

4. Debugging

   • Gotcha: Cryptic API responses without logging.
   • Tip: Enable Guzzle middleware for debugging:

     $client->setDebug(true); // If supported
     // Or manually log responses:
     Log::debug('Karma API Response:', $response->getBody());
     

5. Extension Points

   • Tip: Override core methods for custom logic:

     class CustomKarmacracyClient extends KarmacracyClient {
         public function getKarmaPoints($userId) {
             $response = parent::getKarmaPoints($userId);
             return $this->transformResponse($response);
         }
     }
     

6. Testing

   • Gotcha: Lack of mocking support for API calls.
   • Tip: Use Laravel’s HTTP tests or Mockery:

     $mock = Mockery::mock(KarmacracyClient::class);
     $mock->shouldReceive('getKarmaPoints')->andReturn(['points' => 100]);
     

7. Documentation Gaps

   • Tip: Refer to the Karmacrazy API docs (if available) for endpoint specifics.
   • Workaround: Use var_dump() or dd() on responses to infer structure:

     dd($client->getKarmaPoints('test@example.com'));
