Building Production-Grade Real-Time Systems: The BFF Pattern for Event-Driven Dashboards

This architecture pattern demonstrates how to properly separate concerns in real-time systems by introducing a Backend-for-Frontend (BFF) layer, preventing frontend complexity bloat while enabling true event-driven data delivery. The approach showcases a production-tested strategy for handling multiple asynchronous data streams through Kafka and Socket.IO, offering valuable lessons for building scalable real-time applications that gracefully handle failures and data domain complexity.
