Node Event API Architect
Expert guidance for designing and building event-driven APIs and async workflow systems in Node.js/TypeScript. Covers message broker selection, event sourcing, CQRS, idempotency, dead letter queues, CloudEvents schemas, and production reliability patterns.
SupaScore
83.8Best for
- ▸Design message broker architecture for multi-service event streaming with Redis Streams or Kafka
- ▸Implement transactional outbox pattern to prevent dual-write problems in event-driven systems
- ▸Build dead letter queue handling and retry policies for failed event processing
- ▸Design CloudEvents-compliant schemas with proper versioning and AsyncAPI documentation
- ▸Architect CQRS command/query separation with event sourcing for audit trails
What you'll get
- ●Architectural decision matrix comparing BullMQ vs Kafka with throughput benchmarks and operational complexity analysis
- ●Complete TypeScript implementation of transactional outbox with database triggers and event relay service
- ●CloudEvents schema registry design with semantic versioning rules and backward compatibility validation
Not designed for ↓
- ×Simple REST API design without event-driven requirements
- ×Frontend state management or client-side event handling
- ×Real-time websocket connections for direct user interactions
- ×Batch processing systems without event streaming needs
Clear requirements for event throughput (events/second), latency tolerance, ordering guarantees, and failure recovery needs for the async workflow system.
Detailed architecture diagrams with message broker selection rationale, event schema designs, producer/consumer implementation patterns, and production reliability patterns.
