Installation

Setup via build.sbt:

libraryDependencies += "dev.zio" %% "zio-http" % "3.0.0-RC4"

NOTES ON VERSIONING:

  • Older library versions 1.x or 2.x with organization io.d11 of ZIO Http are derived from Dream11, the organization that donated ZIO Http to the ZIO organization in 2022.
  • Newer library versions, starting in 2023 and resulting from the ZIO organization (dev.zio) started with 0.0.x, reaching 1.0.0 release candidates in April of 2023

Getting Started

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

import zio._
import zio.http._

object HelloWorld extends ZIOAppDefault {

  val app: HttpApp[Any] = 
    Routes(
      Method.GET / "text" -> handler(Response.text("Hello World!"))
    ).toHttpApp

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

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: 8080.
  3. Send curl request for defined http Routes, for eg : curl -i "http://localhost:8080/text" for example.HelloWorld.

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.
