Use this to create utility functions that add bindings mutably to the current module, as opposed to creating new modules and including them.

Set bindings are useful for implementing event listeners, plugins, hooks, http routes, etc.
Set bindings are useful for implementing event listeners, plugins, hooks, http routes, etc.
To define a multibinding use
.many
and.add
methods in ModuleDef DSL:import cats.effect._, org.http4s._, org.http4s.dsl.io._, scala.concurrent.ExecutionContext.Implicits.global import distage._ object HomeRouteModule extends ModuleDef { many[HttpRoutes[IO]].add { HttpRoutes.of[IO] { case GET -> Root / "home" => Ok(s"Home page!") } } }
Set bindings defined in different modules will be merged together into a single Set. You can summon a created Set by type
Set[T]
:import cats.implicits._, org.http4s.server.blaze._, org.http4s.implicits._ object BlogRouteModule extends ModuleDef { many[HttpRoutes[IO]].add { HttpRoutes.of[IO] { case GET -> Root / "blog" / post => Ok("Blog post ``$post''!") } } } class HttpServer(routes: Set[HttpRoutes[IO]]) { val router = routes.foldK def serve = BlazeBuilder[IO] .bindHttp(8080, "localhost") .mountService(router, "/") .start } val objects = Injector().produce(HomeRouteModule ++ BlogRouteModule) val server = objects.get[HttpServer] val testRouter = server.router.orNotFound testRouter.run(Request[IO](uri = uri("/home"))).flatMap(_.as[String]).unsafeRunSync // Home page! testRouter.run(Request[IO](uri = uri("/blog/1"))).flatMap(_.as[String]).unsafeRunSync // Blog post ``1''!

Modify a value bound at

.Modify a value bound at

. Modifiers stack and are all applied beforeT
is added to the object graph; only the final instance is observable.import distage.{Injector, ModuleDef} Injector().produceGet[Int](new ModuleDef { make[Int].from(1) modify[Int](_ + 1) modify[Int](_ + 1) }).use(i => println(s"Got `Int` $i")) // Got `Int` 3
You can also modify while summoning additional dependencies:
modify[Int]("named").by(_.flatAp { (adder: Adder, multiplier: Multiplier) => int: Int => multiplier.multiply(adder.add(int, 1), 10) })
