Then you are ready to use Lepus, for tutorial continue to documentation site!
Also please drop a ⭐ if this project interests you. I need encouragement.


If you have ever used Skunk you might agree with me on how much it's fun to use and meanwhile insightful for its users. This project started with this in mind and I hope it achieves its goals.

I mean, why not use the official java client and use Lepus instead?

I'm not in a position to tell you what you should use, but if you are tired of wrappers over the java client, or want to use more advanced features of RabbitMQ that are not available in other Scala clients, or if you want a clean purely functional client for RabbitMQ (or other AMQP compliant message brokers) take a look at this library and then assess your requirements. You can see features for some more information.

What in the world is Lepus?

Lepus1 (/ˈliːpəs/, colloquially /ˈlɛpəs/) is a constellation lying just south of the celestial equator. Its name is Latin for hare. It is located below—immediately south—of Orion (the hunter), and is sometimes represented as a hare being chased by Orion or by Orion's hunting dogs.


This software is a perpetual beta release, while it might be totally okay to use it in production for most cases, it's worthy to mention that you need to manage your risks carefully!
