Version Matrix


Latest version

A cabbit is a fictional hybrid between a cat and a rabbit.

The main goal of the library is to wrap rabbit-client with cats-effect & fs2. The wrapper is intended to be thin and resemble the client. fs2 & amqp-client are the only dependencies.


cabbit is cross built for scala "2.12.15" | "2.13.7" | "3.1.0" & ce2 | ce3. Thus, you can choose from these artifacts:

ce 3.2.9(through fs2 3.2.2) ce 2.5.4 (through fs2 2.5.10)
scala 2.12.15 cabbit_2.12 cabbit_ce2_2.12
scala 2.13.7 cabbit_2.13 cabbit_ce2_2.13
scala 3.1.0 cabbit_3 cabbit_ce2_3

For ce3 versions add this instruction to your build.sbt:

libraryDependencies += "ru.delimobil" %% "cabbit" % "0.1.2"

For ce2 versions replace cabbit with cabbit_ce2. To use circe encoders add this artifact to your build.sbt:

libraryDependencies += "ru.delimobil" %% "cabbit-circe" % "0.1.2"


This is how you can publish an arbitrary class to RabbitMQ:

    import ru.delimobil.cabbit.encoder.json.jsonUtf8

    case class Message(from: String, msg: String)    
    val node = CabbitNodeConfig(host, port)
    val config = CabbitConfig(, "/")
    val exchange = ExchangeName.default
    val rk = RoutingKey("teaser-example-queue")
    val msg = Message("TeaserPublishApp", "hello from cabbit")
      .provide[IO](config, sslContext = None)
      .use(_.basicPublish(exchange, rk, msg))
