Explain how the two programming models, the Aura and the Lightning Web Framework coexist together?

Answer»

We can mix up the Aura and LWC components. The ultimate parent component is Aura. Auras contain both LWC and Aura components, whereas Lightning WEB Components only have their own component.
If Aura and LWC components are ENCLOSED within a parent, they can interact in a variety of ways:

  • Using application and component events to interact directly with the CHILD component.
  • Receive DATA and interact with child component methods and attributes provided through public APIs using JS CustomEvent objects.
  • Lightning Data Service (LDS) allows both the Aura components and LWC to receive and transfer data. There is currently no communication mechanism between Aura and Lightning web components that are not in the same hierarchy.
