circe-kafka's Introduction

Circe-Kafka

Build Status Maven Central

Implicitly turn your Encoder and Decoder instances into Serializer, Deserializer and Serde.

Artifact

circe-kafka is cross-compiled against Scala 2.12 and 2.13.

libraryDependencies ++= "com.nequissimus" %% "circe-kafka" % "2.7.0"

Note that this library attempts to match the Kafka version.

Usage

import io.circe.{ Decoder, Encoder }
import org.apache.kafka.common.serialization.{ Deserializer, Serde, Serializer }

final case class Foo(i: Int)

//

import nequi.circe.kafka._

implicit val encoder: Encoder[Foo] = ... // for example by importing io.circe.generic.auto._
implicit val decoder: Decoder[Foo] = ...

val serializer: Serializer[Foo] = implicitly
val deserializer: Deserializer[Foo] = implicitly
val serde: Serde[Foo] = implicitly

circe-kafka's Issues

Rename implicit defs to avoid name clashes in companion object

When declaring serializers as val in the companion object of a case class, the implicit resolution is broken due to the name clash.

Workaround is to import the library with renames import nequi.circe.kafka.{ serializer => genSerializer, deserializer => genDeserializer, serde => genSerde }, but I would suggest changing the names in the library as this is a hassle and the name doesn't actually matter.
