In Eclipse Vert.x 3.6.0 the RabbitMQ client will get a new consumer API. In this post we are going to show the improvements since the previous API and how easy it is to use now.

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.

I recently added GraphQL support to Gentics Mesh and I thought it would be a good idea to boil down the essence of my implementation in example so that I could share it in a simpler form. The example I’m about to show will not cover all aspects that I have added to the Gentics Mesh API (e.g. paging, search and error handling) but it will give you a basic overview of the parts that I put together. GraphQL does not require a GraphDB even if the name might suggest it.

The Vert.x team is pleased to announce the release of Eclipse Vert.x 3.5.0.

Eclipse Vert.x is a versatile toolkit, and as such it does not have any strong opinion on the tools that you should be using.

In this article we will see how to sett up the new Vert.x MQTT client. Actually, I have a real example so you can try it quickly.

it’s summer time and we have just released Vert.x 3.5.0.Beta1!

I could not attend the last Eclipse Vert.x community face-to-face meeting last fall, but one item that was discussed is the need for guides aimed at certain types of developers. One of my missions as part of joining the team was to work on this and I’m very happy to share it with you today!

This post is an introduction to the Vert.x-Swagger project, and describe how to use the Swagger-Codegen plugin and the SwaggerRouter class.

Eclipse Vert.x executes periodic and delayed actions with periodic and one-shot timers. This is the base for time scheduling and reach feature extension must be rather interesting. Be notified at certain date / time, take into account holidays, repeat notifications until a given date, apply time zone, take into account daylight saving time etc. There are a lot of useful features time scheduler may introduce to the Vert.x stack.

Nowadays, there are multiple tech stacks to build a real-time web app. What are the best choices to build real-time Angular client apps, connected to a JVM-based backend? This article describes an Angular+Vertx real-time architecture with a Proof of Concept demo app.
