ZIO Http is a scala library for building http apps. It is powered by ZIO and netty and aims at being the defacto solution for writing, highly scalable and performant web applications using idiomatic scala.

Setup via build.sbt:

libraryDependencies += "dev.zio" %% "zio-http" % "0.0.4"

NOTE: ZIO Http is compatible with ZIO 1.x and ZIO 2.x.

A simple Http server can be built using a few lines of code.

import zio._
import zio.http._
import zio.http.model.Method

object HelloWorld extends ZIOAppDefault {

  val app: HttpApp[Any, Nothing] = Http.collect[Request] {
    case Method.GET -> !! / "text" => Response.text("Hello World!")
  }

  override val run =
    Server.serve(app).provide(Server.default)
}

1. Edit the RunSettings - modify className to the example you'd like to run.
2. From sbt shell, run ~example/reStart. You should see Server started on port: 8080.
3. Send curl request for defined http Routes, for eg : curl -i "http://localhost:8080/text" for example.HelloWorld.

You can use the sbt-revolver plugin to start the server and run it in watch mode using ~ reStart command on the SBT console.
