Integration with uPickle

Records can be converted to/from JSON by using uPickle.

Installation

You need an additional module to use records integrated with uPickle.

libraryDependencies ++= Seq(
  "com.github.tarao" %% "record4s-upickle" % "0.12.0"
),

From / To JSON

Importing Record.readWriter enables uPickle to decode/encode records in the ordinary way.

import com.github.tarao.record4s.%
import com.github.tarao.record4s.upickle.Record.readWriter
import upickle.default.{read, write}

type Person = % { val name: String; val age: Int }

val json = """{"name":"tarao","age":3}"""
// json: String = "{\"name\":\"tarao\",\"age\":3}"

// Read from JSON
val r = read[Person](json)
// r: % {
//   val name: String
//   val age: Int
// } = %(name = tarao, age = 3)

// Write it back
write(r)
// res0: String = "{\"name\":\"tarao\",\"age\":3}"
