The library is based on cats-effect 3 since 7.0.0 version, for cats-effect 2.x.x back ports use [series/6.x.x](https://github.com/evolution-gaming/pubsub/tree/series/6.x.x)

### Typesafe layer for DistributedPubSubMediator

```scala

trait PubSub[F[_]] {

  def publish[A: Topic : ToBytes](

    msg: A,

    sender: Option[ActorRef] = None,

    sendToEachGroup: Boolean = false

  ): F[Unit]

  def subscribe[A: Topic : FromBytes : ClassTag](

    group: Option[String] = None)(

    onMsg: OnMsg[F, A]

  ): Resource[F, Unit]

  def topics(timeout: FiniteDuration = 3.seconds): F[Set[String]]

}

```

### Ability to serialize/deserialize messages to offload akka remoting and improve throughput

Check `DistributedPubSubMediatorSerializing.scala`

## Setup

```scala

addSbtPlugin("com.evolution" % "sbt-artifactory-plugin" % "0.0.2")

libraryDependencies += "com.evolutiongaming" %% "pubsub" % "7.0.0"

```

## CHANGELOG

### 7.0.0

##### Upgrades

- cats-effect 2.5.4 to 3.3.11
