Rules of Thumb

You probably don't need NgRx

• Consider

  • Service with Behavior Subject

  • Container Presenter

  • Easy upgrade path to NgRx

Container/Presenter

Container

• Interacts with the store

• Pass observable streams via async pipe

• Receive events from child presenter components

• Decide what to do with events/data

Presenter

• 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.
