kafka-client

A javascript client for kafka

Why the client

The purpose of this client has been to get hands on experience with kafka.

This client does not interact with Kafka directly but relies on kafka-node for this interaction. It is more focused on simplifying the API interface rather than the technical with a kafka cluster. There are other node libraries to interact with kafka such as node-rdkafka.
By using this client it will possible to switch to using a different kafka interaction package in the future without having to change upstream code. For instance if kafka-rdnode evolves faster than kafka-node
