## What it is
node-rdkafka is a high-performance Node.js client for Apache Kafka that wraps the native librdkafka C/C++ library. It handles partition balancing, broker management, producing, and consuming messages with the performance of the native client.

## Use cases
- produce messages to kafka from nodejs
- consume kafka topics in a node app
- high-throughput kafka streaming client
- build event-driven microservices with kafka
- connect nodejs to apache kafka brokers
- native kafka bindings for node

## When to choose
- you need maximum kafka throughput in Node.js via librdkafka
- you need low-level kafka features like partitioning and broker management
- you are building event streaming pipelines in Node.js

## When to avoid
- you want a pure-JavaScript kafka client to avoid native compilation
- you target platforms where building native addons is difficult
- you only need a simple high-level consumer with minimal setup

## Facets
- artifact type: library
- maturity: active
- function: message-queue, streaming, http-client
- domain: microservices, backend, developer-tools
- platform: windows
- tags: kafka, librdkafka, native-bindings, event-streaming, producer-consumer, messaging, nodejs, linux, macos
