Apache Kafka with Node.js Tutorials

Apache Kafka is a distributed event-streaming platform for building real-time, event-driven systems. This complete course covers Kafka architecture, topics, partitions, KafkaJS producers and consumers, delivery guarantees, schemas, stream processing, microservices, security, testing, monitoring, and performance with Node.js.

What Is Apache Kafka?

Apache Kafka is a distributed, log-based event-streaming platform. Producers append events to partitioned topics and consumer groups read them independently, enabling high-throughput, fault-tolerant pipelines that decouple the services in a system.

Why Learn Kafka with Node.js?

Node.js pairs naturally with Kafka for event-driven backends, and KafkaJS is a mature, pure-JavaScript client. Learning Kafka lets you build streaming data pipelines, decouple microservices, and process events reliably at scale.

What You Will Learn

This course is organized into focused lessons so you can learn step by step. You will start with Kafka architecture, topics, and partitions, then move through KafkaJS producers and consumers, offsets and delivery guarantees, serialization and schemas, stream processing, microservice patterns, security, testing, monitoring, and performance.
