Hi , why we can't we use constructor to fetch the data through apex ? as per the documentation, connectedcallback is always used to initilaize the data.

@ferbragga Жыл бұрын

when should I use the connectedCallback() instead of the wire decorator for fetching records that are dependant on public properties? Usually my goto is the wire decorator.

@CodingWithTheForce Жыл бұрын

There are plenty of situations but one of the more common scenarios I can think of is when you need to elevate record, object or field level access. Also when you’re building more generic/abstract components wire decorators can be somewhat limiting.

Also, the wire decorator by default works only by enabling cacheable on the client and if you go with imperative syntax, you have to take care of the cache. The lightning UI API adapters work only with the wire decorator.
