Technical Implementation Details

Circuit Breaker Pattern

Tous les carriers héritent de BaseCarrierConnector qui implémente:

✅ Circuit breaker avec opossum library
✅ Exponential backoff retry
✅ Timeout 5 secondes par défaut
✅ Request/response logging
✅ Error normalization
✅ Health check monitoring

Rate Search Flow

sequenceDiagram
    User->>Frontend: Search rates
    Frontend->>Backend: POST /api/v1/rates/search
    Backend->>RateSearchService: execute()
    RateSearchService->>Cache: Check Redis
    alt Cache Hit
        Cache-->>RateSearchService: Return cached rates
    else Cache Miss
        RateSearchService->>Carriers: Parallel query (5 carriers)
        par Maersk
            Carriers->>Maersk: Search rates
        and MSC
            Carriers->>MSC: Search rates
        and CMA CGM
            Carriers->>CMA_CGM: Search rates
        and Hapag
            Carriers->>Hapag: Search rates
        and ONE
            Carriers->>ONE: Search rates
        end
        Carriers-->>RateSearchService: Aggregated results
        RateSearchService->>Cache: Store (15min TTL)
    end
    RateSearchService-->>Backend: Domain RateQuotes[]
    Backend-->>Frontend: DTO Response
    Frontend-->>User: Display rates

Error Handling Strategy

Tous les carriers implémentent "fail gracefully":

try {
  // API call
  return rateQuotes;
} catch (error) {
  logger.error(`${carrier} API error: ${error.message}`);

  // Handle specific errors
  if (error.response?.status === 404) return [];
  if (error.response?.status === 429) throw new Error('RATE_LIMIT');

  // Default: return empty array (don't fail entire search)
  return [];
}
