  glngn server is a low-code business process as a service rapid development system.

  glngn server is a low-code business process as a service rapid development system. Conceptually similar to a programmable Microsoft Access or Apple FileMaker for scalable event sourced business services. In addition to a library, a standalone application is provided that is useful with minimal ceremony. This can be customized with a simple API. As well as deployed to a kubernetes cluster should those advantages be required.

  A deployment is cluster of glngn.server.node.AppNodes serving a dynamic composition of glngn.server.ServiceFragments. Deployments are designed to be fully usable as a standalone local application or a kubernetes service.

  • If your goal is to restrict the configuration or prelude to better suite a business domain then see glngn.server.host.HostApp.
  • If you are debugging a failure of a glngn server process and have the exit code then see glngn.server.host.ExitCodes$

•  trait ServiceEntity extends ServiceActor

  An event sourced persistent entity definition.

  An event sourced persistent entity definition. The entity refers to all actors defined by the the Id.

  This is implemented using typed akka persistent actors and cluster sharding. Additional functionality:

  - always replies when handing a request - will automatically derive a JSON codec for Storage events - StopEnvelope will always stop the entity - entity will automatically passivate after no events

  import glngn.server.prelude._
  
  final object MyServiceEntity extends ServiceEntity {
    val name = "my-service-entity"
  
    // example declaration of state as case class
    final case class State(state: String) extends Message
  
    // standard Proto and Storage declarations as sealed traits
    sealed trait Proto extends Message
    sealed trait Storage extends Proto
  
    // a request event that's recorded to storage
    final case class Add(value: String) extends Command[State] with Storage with Proto
  
    def activity(injector: ImpureInjector, id: Id) = new Activity(injector) {
      val init = State(Map.empty)
  
      def protoHandler(ctx: ActorContext[Envelope], state: State) = {
        case persistedEvent: Storage => Handler.persist(persistedEvent)
        case _: Proto                => Handler.none
      }
  
      def storageHandler(state: State) = {
        case add: Add => state.copy(state = state.state + add.value)
      }
    }
