Apache Kafka enables building scalable event-driven systems with reliable message streaming between services. As the creator of CoreUI with over 10 years of Node.js experience since 2014, I’ve built Kafka-based architectures for real-time data processing, event sourcing, and microservice communication. The standard approach uses the KafkaJS library to create producers and consumers that connect to Kafka clusters. This provides high-throughput, fault-tolerant messaging for distributed systems.
