If you visited the Eclipse Vert.x website recently, you might have noticed a couple of novelties on the community page:

Vert.x has already been providing metrics for some time, through the vertx-dropwizard-metrics and vertx-hawkular-metrics modules. Both of them implement a service provider interface (SPI) to collect the Vert.x metrics and make them available to their respective backends.

It’s this time of year again! Google Summer of Code 2018 submission period has just started!

We have just released Vert.x 3.5.1!

Recently I stumbled upon Vertx. Event-driven, asynchronized, lightweight, reactive, highly performant, polyglot application framework. Ideal for writing micro-services. I played around with it for a while and really enjoyed the concept of serverless applications.

As part of my hobby project to control RaspberryPi using Google Home Mini and/or Alexa, I wanted to write a very simple TCP client that keeps a connection open to one of my custom written server in cloud (I will write another blog post to cover the server side on a later date). The requirement of the client is to send a shared secret upon connecting and then keep waiting for message from server. Vert.x, Kotlin and Gradle allow rapid development of such project. The generated jar can be executed on Raspberry Pi. These steps outline the project setup and related source code to showcase a Vert.x and Kotlin project with Gradle.
