This repository shows how to build reactive applications in Java 8 using the Akka framework, on Akka Persistence, with cassandra as backend, and exposing an event sourced stream using HTTP.

In addition, it contains several extensions for kamon that provide insight to a running, clustered akka application.

The repository consists of the following modules:

• ts-reaktive-actors contains the base Java classes with which a reactive application can be built
• ts-reaktive-akka contains Akka additions that haven't been merged in to akka main yet
• ts-reaktive-cassandra contains classes that help using Cassandra in an async way
• ts-reaktive-java contains various utility classes for Java 8
• ts-reaktive-kamon-akka provides dead letter monitoring for an actor system. Just have it on your classpath to enable.
• ts-reaktive-kamon-akka-cluster provides cluster membership monitoring for akka clustering. Just have it on your classpath to enable.
• ts-reaktive-kamon-log4j provides log4j error and warning monitoring. Just have it on your classpath to enable.
• ts-reaktive-marshal provides a non-blocking marshalling DSL for XML and JSON
• ts-reaktive-marshal-akka uses the above marshalling inside akka reactive streams
• ts-reaktive-ssl provides utility classes to read SSL keys and certs in PEM format
• ts-reaktive-testkit provides a test framework for testing akka routes with real HTTP
• ts-reaktive-testkit-assertj provides AssertJ-style assertions for Java 8 CompletionStage (with wait support) and Jackson's JsonNode.

If you use SBT, you can use this library by adding the following:

resolvers += Resolver.bintrayRepo("jypma", "maven")

libraryDependencies ++= {
  val version = "0.0.30"
  Seq(
    "com.tradeshift" %% "ts-reaktive-actors" % version,
    "com.tradeshift" %% "ts-reaktive-akka" % version,
    "com.tradeshift" %% "ts-reaktive-cassandra" % version,
    "com.tradeshift" %% "ts-reaktive-marshal" % version,
    "com.tradeshift" %% "ts-reaktive-marshal-akka" % version,
    "com.tradeshift" %% "ts-reaktive-replication" % version,
    "com.tradeshift" %% "ts-reaktive-ssl" % version,
    "com.tradeshift" %% "ts-reaktive-testkit" % version % "test",
    "com.tradeshift" %% "ts-reaktive-testkit-assertj" % version % "test",
    "com.tradeshift" %% "ts-reaktive-kamon-akka" % version,
    "com.tradeshift" %% "ts-reaktive-kamon-akka-cluster" % version,
    "com.tradeshift" %% "ts-reaktive-kamon-log4j" % version
  )
}
