Getting Started

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

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

object HelloWorld extends App {
  val app = Http.collect[Request] {
    case Method.GET -> !! / "text" => Response.text("Hello World!")
  }

  override def run(args: List[String]): URIO[zio.ZEnv, ExitCode] =
    Server.start(8090, app).exitCode
}

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.
