Getting Started

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

import zhttp.http._
import zhttp.service.Server
import zio._

object HelloWorld extends ZIOAppDefault {

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

  override val run =
    Server.start(8090, app)
}

Steps to run an example

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: 8090.
3. Send curl request for defined http Routes, for eg : curl -i "http://localhost:8090/text" for example.HelloWorld.

Installation

Setup via build.sbt

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

Watch Mode

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