  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 glngn.server.Nodes serving a dynamic composition of glngn.server.ServiceFragments. Deployments are designed to be fully usable as a standalone local application or a kubernetes service.

•  trait ServiceActor extends AnyRef

  ServiceActor is an actor representing a service within the glngn system.

  ServiceActor is an actor representing a service within the glngn system. Conceptually the API can be thought of as a simplified actor API compared to the full akka API. This API is designed to trade constraints for automation.

  The ServiceFragment class is the typical base class for a domain specific addition.

  To declare a new service actor, define a scala object that inherits from this trait with a sealed protocol Proto. EG:

  import glngn._
  import glngn.prelude._
  
  object SuitTailoringOrders extends ServiceActor {
    sealed trait Proto extends Message
  }

  Technical Deep Dive - This usage pattern contains two choices for constraints. 1. service actor will be defined in an object. 2. a sealed trait for Proto.

  goals:

  • Explicit annotations for command and query requests.
  • actor interface required by ActorService.
  • bridge between ActorService and unconstrained Akka
  • low/zero cost lifting of general akka behaviors / protocols
