Installation

To use Vert.x for Scala, add the following dependency to the dependencies section of your build descriptor:

sbt

libraryDependencies += "io.vertx" % "vertx-core" % "4.5.11-SNAPSHOT"
libraryDependencies += "io.vertx" %% "vertx-lang-scala" % "4.5.11-SNAPSHOT"

Gradle

implementation "io.vertx:vertx-core:4.5.11-SNAPSHOT"
implementation "io.vertx:vertx-lang-scala_3:4.5.11-SNAPSHOT"

Maven

<dependency>
  <groupId>io.vertx</groupId>
  <artifactId>vertx-core</artifactId>
  <version>4.5.11-SNAPSHOT</version>
</dependency>
<dependency>
  <groupId>io.vertx</groupId>
  <artifactId>vertx-lang-scala_3</artifactId>
  <version>4.5.11-SNAPSHOT</version>
</dependency>

What is in the package?

As of now, Vert.x for Scala provides

• implicit conversions between Vert.x Futures/Promises and Scala Futures/Promises
• a base class for Verticle implementations, io.vertx.lang.scala.ScalaVerticle
• an ExecutionContext that is given by any ScalaVerticle
• the io.vertx.lang.scala.json.Json object which provides some useful smart constructors and functions
• and generated apply methods for most of Vert.x' Data Objects

At the moment, Vert.x for Scala does not provide generated APIs for Vert.x core or any other module. This is something that is up for the future.
