Retrofit-DSL

Retrofit itself is great but it not design for Kotlin. This small plug-in library will make Retrofit look great on your .kt.

Usage

With Retrofit-DSL our code will look like below.

 var service = retrofitFor<MessagingService> { //this: Retrofit.Builder
     baseUrl(server.url(""))
     addConverterFactory(GsonConverterFactory.create())
 }
 service.getMessage().enqueue {
     always {
        //when response return or failure
     }
     onSuccess { //this: Response<T>
        println(body())
     }
     onError { //this: Response<T>
        println(errorBody<Message>()) //call when response not in 4xx-5xx
     }
     onRedirect { //this: Response<T>
        //3xx
     }
     onClientError { //this: Response<T>
        //4xx
     }
     onServerError { //this: Response<T>
        //5xx
     }
     onFailure { //it: Throwable
        it.printStackTrace()
     }
     finally {
       //Always call afterward
     }
 }

Isn't it good?

Lazy

But If you wanna use more lazy form, Try this below.

  service.getMessage().then { message ->
      println(message)
  }.catch { res, t ->
      res?.let { doSomething(it) } // res return when request not successful
      t?.let { alert(it) } //throwable return on failure
  }.finally {
    dialog.dismiss() //Always call afterward
  }

catch() and finally() are optional
