A HAL library based on Play-JSON.
To use this library, add the following settings to your build definition:
resolvers += "restful-scala" at "https://dl.bintray.com/restfulscala/maven"
libraryDependencies += "org.restfulscala" %% "halselhof" % "0.3.0"
libraryDependencies += "com.typesafe.play" %% "play-json" % "2.6.3"
You need to add the play-json
dependency explicitly, as HALselhof assumed it is being provided by your application. If you use this library with the Play framework, play-json should already be on your classpath.
// Test data which should be reflected in the resource state
case class TestData(total: Int, currency: String, status: String)
// a generated play.api.libs.json.Writes
implicit val testWrites = Json.writes[TestData]
// transfer the resource state into a full HAL resource
val data = TestData(20, "EUR", "shipped")
val resource: HalResource = data.asResource ++
HalLink("self", "/orders") ++
HalLink("next", "/orders?page=2") ++
HalLink("find", "/orders{?id}", templated = true)
// transfer the resource to the Play JSON AST
val json = resource.json
// within a Play Controller HAL resources can be serialized directly and are supported within content negotiation
import play.api.hal._
import play.api.mvc.hal._
def halOrJson = Action { implicit request =>
render {
case Accepts.Json() => Ok(Json.obj("foo" -> "bar"))
case AcceptHal() => Ok(Hal.state(Json.obj("foo" -> "bar")) ++ HalLink("self", "/foo"))
}
