Fun.CQRS is a Scala CQRS/ES framework. It provides the basic blocks to build event driven aggregates with Event Sourcing.

Fun.CQRS provides a out-of-the-box AkkaBackend and a InMemoryBackend for testing. However, it’s designed as such that other backend implementations are possible. For instance, an alternative Akka backend based on Eventuate, a Slick backend or RxScala backend could be implementated and plugged in easily.

Project Information

Project artifact

The artifacts are published to Sonatype Repository. Simply add the following to your build.sbt.

libraryDependencies += "io.strongtyped" %% "fun-cqrs-akka" % "1.0.0-SNAPSHOT"

For testing you can include the test kit.

libraryDependencies += "io.strongtyped" %% "fun-cqrs-test-kit" % "1.0.0-SNAPSHOT"

If you want to hack Fun.CQRS and develop your own backend, you can import only the core module. The core module does NOT include the Akka backend.

libraryDependencies += "io.strongtyped" %% "fun-cqrs-core" % "1.0.0-SNAPSHOT"
