Vert.x is a lightweight, high performance application framework that runs on the Java Virtual Machine designed for mobile, web, and enterprise applications. It evolved as direct threat to Node.js for Javascript. Like Node.js, Vert.x is a server framework providing an event-based programming model providing asynchronous API. It has won the award for “Most Innovative Java Technology” at the JAX Innovation awards earlier this year.



The Vert.x application framework boasts of the following features


  • Polyglot

The application components of a polygot can be written in multiple languages. True to the essence of a polygot, a script valid for multiple programming languages; Vert.x supports a variety of languages like Java, JavaScript, CoffeeScript, Ruby, Python or Groovy. In addition, Scala and Closure are planned to be supported. A single app can also support a combination of several programming languages used to write it. Vert.x itself is built in Java. However, Java is not required to use Vert.x.

  • Simplicity

Simplicity is a forgotten skill in programming where developers are tempted to show off their technical skills, overwhelming the users. Vert.x sticks to simple and clear APIs which can be developed and implemented very easily.

  • Scalability

Vert.x promotes a simple, asynchronous programming model for writing truly scalable non-blocking applications. It efficiently utilizes server cores by message passing using non blocking I/O to serve many connections with minimal threads.

  • Concurrency

Vert.x offers simple, single threaded concurrency model and circumvents the nuisances of multi-threaded programming. It means that means that the multi-thread programming effect can be achieved without synchronization, lock, or volatility. This allows the users to focus on the business logic rather than handling the issues that come with multi-threading.

  • Distributed Event Bus

The Distributed Event Bus is at the heart of Vert.x connecting the server-side components written in any language of choice. It spans the client and server side penetrating into the browser JavaScript allowing to create ‘real time’ web applications. Vert.x aims to make a variety of server programs communicate well with each other. With the Event Bus, a server application built with different languages can easily communicate with each other.

  • Web Sockets

Vert.x incorporates WebSockets and SockJS support for real-time server-push applications.

  • Module System

Vert.x has a module system allowing packaging of components into modules for encapsulation and reuse. Sharing of these components can be done on the community using Maven Central and advertising on public module registry.

  •  Seamless Architecture

The seamless architecture promotes running, debugging and testing of the Vert.x applications in IDE of choice.
Auto Redeploy can be used to see changes instantly in a running module.

  • Open Source

Vert.x is completely open source and is licensed under the Apache Software License 2.0


To put it in a nutshell, just like Node.js, Vert.x is a server framework providing an event-based programming model. Therefore, Vert.x API is very similar to that of Node.js. While Node.js is created by using JavaScript,Vert.x is created by using Java. Both keep overshadowing each other but at the end of the day, both are unique with different capabilities.
