Prequel: I have several methods in need of the same @wire operations. The approach I initially took was to make a new
utilities component just for the wire operations and then use the
pubsub library to fire the data that was retrieved.
However I noticed inconsistency in the results. Sometimes that component would fire the event before the consumer components were to register their listeners.
So I remembered that there's
cacheable on the APEX side when using @wire. So I wonder if the results will be cached for all components that use @wire to connect to the same apex method or do the results only cache per component?
The documentation states:
Marking a method as cacheable improves your component’s performance by quickly showing cached data from client-side storage without waiting for a server trip.
But it's not clear to me whether the cache is for all components or is it individual per component.
Additional question: If I have multiple components importing the user ID
import USER_ID from '@salesforce/user/Id'; is that being cached after the first component imports it and then the value gets imported from the client-side for the rest of the components?
