We welcome contributions to KafkaJS, but we also want to see a thriving third-party ecosystem. If you would like to create an open-source project that builds on top of KafkaJS, please get in touch and we'd be happy to provide feedback and support.
Here are some projects that we would like to build, but haven't yet been able to prioritize:
* Dead Letter Queue - Automatically reprocess messages
* ✅ Schema Registry - Now available! thanks to @erikengervall
* Metrics - Integrate with the instrumentation events to expose commonly used metrics
