    Multibindings are useful for implementing event listeners, plugins, hooks, http routes, etc.

    Multibindings 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!") }
      }
    }

    Multibindings defined in different modules will be merged together into a single Set. You can summon a multibinding by type Set[_]:

    import cats.implicits._, import org.http4s.server.blaze._, import 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''!
