For more information see the documentation for implementing Kalix services in Java or Scala.

Parts of the Kalix Java/Scala SDK

• user-facing packages

  • kalix-java-sdk and kalix-scala-sdk The Java/Scala API to build services in Kalix (backed by an implementation in Scala based on Akka gRPC).

    See Developing with Java or Scala.

  • kalix-java-sdk-testkit and kalix-scala-sdk-testkit A library to implement integration tests for services with Junit 4 or 5, based on TestContainers. Also contains library parts of unit TestKit.

  • samples Small example services to illustrate Kalix features. The code provides snippets for the documentation.

• developer tooling

  • codegen/core, codegen/java-gen, codegen/scala-gen Tooling to generate code from Protobuf with annotations.
  • maven-java Maven tooling
    • kalix-maven-plugin Maven plugin to trigger code generation.
    • kalix-maven-archetype-event-sourced-entity Maven archetype to create a project with an Event-sourced Entity.
    • kalix-maven-archetype-value-entity Maven archetype to create a project with a Value Entity.
  • sbt-plugin sbt plugin for code generation.
  • sbt new (gitter8) templates:
    • lightbend/kalix-value-entity.g8
