Helion Green-box Console - client

High level architecture

Three layers plus event bus:

Three layers (from top to bottom)

  • View (MVVC) layer - where angular directive, controllers are defined.
  • Model layer - where business data objects are defined with methods to retrieve/update the data.
  • API layer - where API objects are defined, which handle http request.

Between layers, each layer can only access the layer directly under it. This means

OK

  • Model layer -> API layer
  • View (MVVC) layer -> Model layer

NOT OK

  • Model layer -> View (MVVC) layer
  • API layer -> View (MVVC) layer
  • API layer -> Model layer
  • View (MVVC) layer -> API layer

Event bus

Event bus cross all the layers. Each layer can access the event bus. Event bus provides a loose-coupling approach to allow communications between:

  • Model layer -> View (MVVC) layer
  • API layer -> View (MVVC) layer
  • API layer -> Model layer
  • View (MVVC) layer -> API layer
