This tiny project is a sort of experimental toolset which aims to allow developers use Finch more efficiently and with less boilerplate.
For now it offers only one thing to simplify your life with Finch: controllers implemented without any kind of runtime reflection.
For now there is only one module available. You can use the following sbt snippet to install it:
- for the stable release:
libraryDependencies ++= Seq(
"ru.arkoit" %% "finchrich-controller" % "0.1.2"
)- for the
SNAPSHOTversion:
resolvers += Resolver.sonatypeRepo("snapshots")
libraryDependencies ++= Seq(
"ru.arkoit" %% "finchrich-controller" % "0.2.0-SNAPSHOT"
)FinchRich up to 0.1.2 supports both Scala 2.10.6 and 2.11.8. In FinchRich 0.2.0 Scala 2.10.6 support will be dropped. Support for Scala 2.12 will be introduced shortly after Finch will support it.
As mentioned above, for now the project consists of the only module: finchrich-controller.
First of all it allows you to define Finch endpoints within the controllers and extract them later in the form of endpoints coproducts:
import io.finch._
import ru.arkoit.finchrich.controller._
object MyAwesomeController extends Controller {
val healthcheck = get("healthcheck") { Ok() }
val greeter = get("greet" / param("name")) { name: String => Ok(s"Hello, $name!") }
}
// Get the coproduct of all endpoints from the MyAwesomeControlller
val ep = controllerToEndpoint(MyAwesomeController)
// ... or the same thing in finchrich >= 0.2.0
val ep = MyAwesomeController.toEndpointAlso it allows you to nest controllers like this:
import io.finch._
import ru.arkoit.finchrich.controller._
object MyAwesomeController extends Controller {
val healthcheck = get("healthcheck") { Ok() }
val greeter = get("greet" / param("name")) {name: String => Ok(s"Hello, $name!") }
}
object AnotherAwesomeController extends Controller {
val joke = get("joke") { Ok("""Chuck Norris died 20 years ago,
Death just hasn't built up the courage to tell him yet.""") }
}
object MainController extends Controller {
val c1 = MyAwesomeController
val c2 = AnotherAwesomeController
}
// Get the coproduct of all endpoints from the MainController and nested controllers
val ep = controllerToEndpoint(MainController)
// ... or the same thing in finchrich >= 0.2.0
val ep = MainController.toEndpointAll of this stuff does not use any kind of runtime reflection and is actually implemented as a whitebox macros. It expands in something that you usually write by hand, like this:
val ep = MainController.c1.healthcheck :+: MainController.c1.greeter :+: MainController.c2.joke
