[DevoxxBE2013] Introducing Vert.x 2.0: Taking Polyglot Application Development to the Next Level
Tim Fox, the visionary project lead for Vert.x at Red Hat, charts the course of this lightweight, high-performance application platform for the JVM. With a storied tenure at JBoss and VMware—where he spearheaded HornetQ messaging and RabbitMQ integrations—Tim unveils Vert.x 2.0’s maturation into an independent powerhouse. His session delves into the revamped module system, Maven/Bintray reusability, and enhanced build tool/IDE synergy, alongside previews of Scala, Clojure support, and Node.js compatibility.
Vert.x 2.0 empowers polyglot, reactive applications, blending asynchronous eventing with synchronous legacy APIs via worker verticles. Tim’s live demos illustrate deploying modules dynamically, underscoring Vert.x’s ecosystem for mobile, web, and enterprise scalability.
Core API Refinements and Asynchronous Foundations
Tim highlights Vert.x’s event-driven core, refined in 2.0 with intuitive APIs for non-JVM languages. He demonstrates verticles—lightweight actors—for handling requests asynchronously, avoiding blocking calls.
This reactive model, Tim explains, scales to thousands of connections, ideal for real-time web apps, contrasting traditional thread-per-request pitfalls.
Module System and Ecosystem Expansion
The new module system, Tim showcases, leverages Maven repositories for seamless dependency management. He deploys a web server via module names, pulling artifacts from Bintray—eliminating manual installations.
This reusability fosters a vibrant ecosystem, with core modules for HTTP, MySQL (via reversed-engineered async drivers), and more, enabling rapid composition.
Build Tool and IDE Integration
Vert.x 2.0’s Maven/Gradle plugins streamline development, as Tim demos: configure a pom.xml, run mvn vertx:run, and launch a cluster. IDE support, via plugins, offers hot-reloading and debugging.
These integrations, Tim notes, lower barriers, allowing developers to iterate swiftly without Vert.x-specific tooling.
Polyglot Horizons: Scala, Clojure, and Node.js
Tim previews Scala/Clojure bindings, enabling functional paradigms on Vert.x’s event bus. Node.js compatibility, via drop-in modules, bridges JavaScript ecosystems, allowing polyglot teams to collaborate seamlessly.
This inclusivity, Tim asserts, broadens Vert.x’s appeal, supporting diverse languages without sacrificing performance.
Worker Verticles for Legacy Compatibility
For synchronous APIs like JDBC, Tim introduces worker verticles—executing on thread pools to prevent blocking. He contrasts with pure async MySQL drivers, offering flexibility for hybrid applications.
This pragmatic bridge, Tim emphasizes, integrates existing Java libraries effortlessly.
