**akka-stream-netty** is a scala lib to adapt [netty](https://netty.io) transport to [akka-stream](https://doc.akka.io/docs/akka/current/stream/index.html), which let us can use native transport with:

  - epoll

  - kqueue

  - unix domain socket

> [alpakka-unix-domain-socket](https://github.com/akka/alpakka) would be a alternative if you only want to use unix domain socket.

# Dependencies

```scala

libraryDependencies += "com.github.zhongl" %% "akka-stream-netty-all" % 

```

# Usage

```scala

import java.net._

import scala.concurrent.duration._

import akka.actor.ActorSystem

import akka.stream.ActorMaterializer

import akka.stream.scaladsl._

import akka.util.ByteString

import io.netty.channel.socket._

import zhongl.stream.netty._

import all._

implicit val system = ActorSystem("demo")

implicit val mat = ActorMaterializer()

implicit val ec = system.dispatcher

Netty().bindAndHandle[ServerSocketChannel](Flow[ByteString].map(identity), new InetSocketAddress("localhost", 8080)).flatMap { sb =>

  Source.repeat(ByteString("a"))

    .delay(1.seconds) 

    .via(Netty().outgoingConnection[SocketChannel](sb.localAddress))

    .runForeach(println)

    .flatMap(_ => sb.unbind())    

}

```
