Kafka client

I have a Kafka client I started on called nectar, it's been a while since I worked on it. I might come back to it some day, but for now other projects have taken my interest. But if someone wants to fork and run with it, feel free!

Awesome!

For this client, would the hope be that it work for both the Erlang & JavaScript targets? In nectar I was planning on pretty heavily making use of actors, and also there's a lot of non-byte aligned decoding & encoding going on.

I suspect there's not much one could share between the two targets here, but if there's any protocol stuff which could be shared that would be great.

Good call out! I'd stubbed out a project (ambrosia) to work on some codegen for making decoders and encoders. The Kafka protocol gets a bit weird with its versioning, I'm not sure the best way to represent that in Gleam. But, if I never get to it here's some resources I've come across that could help someone else get a protocol library up and running:

• Apache keeps all their protocol messages in (what I think is) a proprietary JSON format in their Kafka Github repo .
• The project kafka-protocol-rs has been a great reference for protocol stuff, and it's where I got the initial idea for codegen.
• And if someone is just getting started, Apache's Kafka protocol documentation is a huge help.
