circe

The ciris-circe module provides ConfigDecoders for JSON using circe.

Getting Started

To get started with sbt, add the following line to your build.sbt file.

libraryDependencies += "is.cir" %% "ciris-circe" % "3.15.2"

If you are using Scala.js or Scala Native, make sure to replace %% with %%% above.

Usage

import ciris._
import ciris.circe._
import io.circe.Decoder

case class SerialNumber(value: String)

object SerialNumber {
  implicit val serialNumberDecoder: Decoder[SerialNumber] =
    Decoder[String].map(apply)

  implicit val serialNumberConfigDecoder: ConfigDecoder[String, SerialNumber] =
    circeConfigDecoder("SerialNumber")
}

env("SERIAL").as[SerialNumber]
// res0: ConfigValue[Effect, SerialNumber] = ConfigValue$19404417
