Collmex Bundle Laravel Package

Getting Started

Minimal Setup

1. Installation Run composer require coffeebike/collmex-bundle in your Symfony project directory. Verify the package appears in composer.json under require.

2. Enable the Bundle Add new CoffeeBike\CollmexBundle\CoffeeBikeCollmexBundle() to the registerBundles() method in AppKernel.php (Symfony 2/3) or config/bundles.php (Symfony 4+).

3. Configure Credentials Add Collmex API credentials to config/packages/coffee_bike_collmex.yaml (Symfony 4+) or app/config/config.yml (Symfony 2/3):

   coffee_bike_collmex:
       user: 'your_collmex_username'
       password: 'your_api_password'
       customer_id: 'your_customer_id'
   

4. First Use Case: Fetching Orders Inject the CollmexClient service into a controller or service:

   use CoffeeBike\CollmexBundle\Service\CollmexClient;
   
   class OrderController extends AbstractController
   {
       public function __construct(private CollmexClient $collmex)
       {
       }
   
       public function index()
       {
           $orders = $this->collmex->getOrders();
           return $this->render('orders/index.html.twig', ['orders' => $orders]);
       }
   }
   

Implementation Patterns

Core Workflows

1. Service Integration The bundle provides a CollmexClient service for API interactions. Use dependency injection to access it:

   // Example: Fetching order details
   $order = $this->collmex->getOrder($orderId);
   

2. Event-Driven Extensions Extend functionality by listening to Collmex events (if supported). Example:

   // config/services.yaml
   services:
       App\EventListener\CollmexOrderListener:
           tags:
               - { name: kernel.event_listener, event: collmex.order.created, method: onOrderCreated }
   

3. Data Transformation Use Symfony’s serializer or custom mappers to transform Collmex responses into domain objects:

   $serializer = $this->container->get('serializer');
   $order = $serializer->deserialize($rawOrder, Order::class, 'json');
   

4. Batch Processing For bulk operations (e.g., syncing orders), implement a command:

   use CoffeeBike\CollmexBundle\Service\CollmexClient;
   use Symfony\Component\Console\Command\Command;
   
   class SyncOrdersCommand extends Command
   {
       protected static $defaultName = 'collmex:sync-orders';
   
       public function __construct(private CollmexClient $collmex)
       {
           parent::__construct();
       }
   
       protected function execute(InputInterface $input, OutputInterface $output): int
       {
           $orders = $this->collmex->getOrders(['limit' => 100]);
           // Process orders...
           return Command::SUCCESS;
       }
   }
   

5. Caching Responses Cache API responses to reduce calls (e.g., using Symfony’s cache system):

   $cache = $this->container->get('cache.app');
   $cacheKey = 'collmex_orders_' . $customerId;
   $orders = $cache->get($cacheKey, function() use ($collmex, $customerId) {
       return $collmex->getOrders(['customer_id' => $customerId]);
   });
   

Gotchas and Tips

Common Pitfalls

1. Deprecated Symfony Version The bundle was last updated in 2016 and may not support Symfony 5/6+. Test thoroughly or fork the project for compatibility.

   • Workaround: Override the CollmexClient service to adapt to newer Symfony versions:

     # config/services.yaml
     services:
         CoffeeBike\CollmexBundle\Service\CollmexClient:
             arguments:
                 $container: '@service_container'
                 $config: '%coffee_bike_collmex%'
     

2. Missing Documentation The bundle lacks detailed API method documentation. Inspect the source (src/Service/CollmexClient.php) for available methods like:

   • getOrders(array $params)
   • getOrder(string $orderId)
   • createOrder(array $data)

3. Authentication Issues

   • Ensure customer_id matches your Collmex account.
   • Verify API credentials are not hardcoded (use environment variables or Symfony’s parameter_bag):

     # .env
     COLLMEX_USER=your_user
     COLLMEX_PASSWORD=your_pass
     COLLMEX_CUSTOMER_ID=123456
     

     # config/packages/coffee_bike_collmex.yaml
     coffee_bike_collmex:
         user: '%env(COLLMEX_USER)%'
         password: '%env(COLLMEX_PASSWORD)%'
         customer_id: '%env(COLLMEX_CUSTOMER_ID)%'
     

4. Rate Limiting Collmex APIs may throttle requests. Implement exponential backoff in custom clients:

   use Symfony\Component\HttpClient\Exception\TransportException;
   
   try {
       $response = $this->httpClient->request('GET', $url);
   } catch (TransportException $e) {
       sleep(2 ** $retryCount); // Exponential backoff
       $retryCount++;
   }
   

5. Error Handling The bundle may not handle HTTP errors (e.g., 404, 500) gracefully. Extend the client:

   class CustomCollmexClient extends CollmexClient
   {
       public function getOrder($orderId)
       {
           try {
               return parent::getOrder($orderId);
           } catch (ClientException $e) {
               $this->logger->error('Collmex API error: ' . $e->getMessage());
               throw new OrderNotFoundException();
           }
       }
   }
   

Debugging Tips

1. Enable API Logging Add a logger to track API calls:

   # config/services.yaml
   services:
       CoffeeBike\CollmexBundle\Service\CollmexClient:
           calls:
               - [setLogger, ['@logger']]
   

2. Inspect Raw Responses Temporarily modify the client to log raw responses:

   $response = $this->httpClient->request('GET', $url);
   $this->logger->debug('Collmex API Response', ['data' => $response->getContent()]);
   

3. Test with Postman Manually test API endpoints using Postman with the same credentials to isolate issues.

Extension Points

1. Custom API Endpoints Extend the client to support unsupported endpoints:

   class ExtendedCollmexClient extends CollmexClient
   {
       public function getShipments($params = [])
       {
           return $this->request('GET', '/shipments', $params);
       }
   }
   

2. Webhook Integration If Collmex supports webhooks, create a Symfony event subscriber:

   class CollmexWebhookSubscriber implements EventSubscriberInterface
   {
       public static function getSubscribedEvents()
       {
           return [
               'kernel.request' => 'onKernelRequest',
           ];
       }
   
       public function onKernelRequest(GetResponseEvent $event)
       {
           if ($event->getRequest()->getPathInfo() === '/collmex/webhook') {
               $this->handleWebhook($event->getRequest());
           }
       }
   }
   

3. Database Sync Use Doctrine events to sync Collmex data with your database:

   // src/EventListener/CollmexSyncListener.php
   class CollmexSyncListener
   {
       public function onOrderCreated(OrderCreatedEvent $event)
       {
           $entityManager = $this->container->get('doctrine')->getManager();
           $order = new OrderEntity();
           // Map Collmex data to entity...
           $entityManager->persist($order);
           $entityManager->flush();
       }
   }
