Awesome APIs with Kotlin, Spring 5 and Swagger

Early last year, Spring announced official support for Kotlin in Spring Framework 5. The news was welcome and exciting, particularly with respect to technologies like Spring Webflux, Project Reactor, and Spring functional, areas where Kotlin very much shines. In this article, I will describe how to bootstrap a new Spring 5 project that integrates Kotlin, Spring Webflux functional, Project Reactor, Swagger, Gradle, and JUnit using kotlin-swagger-spring-functional-template. The template includes two sample REST...

Node.js / Express app generator: with ES.next, API validation, documentation, logging, and more

[Take me to the app generator] I’m at work on a new project. My team and I are building a highly scalable service platform and have elected to build it using the microservices architecture pattern. The platform consists of many microservices, each of which is typically owned by a collaborating team. Teams are empowered to make decisions and choose technologies that best fit the need. This means that services may...

Asynchronous programming with Async / Await and the Scala Play Framework

Asynchronous programming has a number of advantages, most notably is its well touted ability to improve responsiveness. Asynchronous events occur independently of the main program flow and asynchronous actions are executed in a non-blocking, lock-free manner. This, ultimately, allows the main program flow to continue unimpeded, without blocking. On the flips side, asynchronous programming can be difficult to reason about. Many actions are often run simultaneously which can lead to...

Play Framework – Adapting Java 8 CompletableFutures to Play F.Promises

Recently, I have been playing around with Java 8 and the Play Framework (2.4RC1) – bad pun intended :P. As I worked to develop the codebase, I found the need to integrate with Java 8 CompletableFuture‘s. No big deal, right? At first, it didn’t seem to be, but as I continued coding, I quickly became very unhappy with how my code was turning out. The Play Framework for Java introduces...

How to use the Play WS library in a standalone Scala app

The Play WS library makes it possible to execute HTTP requests and process the response asynchronously. It provides an awesome API that is incredibly easy to use. (I’ve provided a few simple WS examples toward the end of this post.) Prior to the release of Play 2.4 (the current 2.4 release is the M2 milestone release), it was possible to utilize the WS API in a standalone Play app, however...
