    • Service with Behavior Subject

    • Container Presenter

    • Easy upgrade path to NgRx



  • Interacts with the store

  • Pass observable streams via async pipe

  • Receive events from child presenter components

  • Decide what to do with events/data


  • Receive plain data from parent

  • Display data/make it pretty

  • User/system events are raised to parent via emitters

    • Decisions are deferred

    • Component is reusable and flexible

  • No knowledge of stores, services, selectors, actions, etc.
