Returning Data from an Apex Server-Side Controller
Return results from a server-side controller to a client-side controller using the
return statement. Results data must be serializable
into JSON format.
Return data types can be any of the following.
- Simple—String, Integer, and so on. See Basic Types for details.
- sObject—standard and custom sObjects are both supported. See Standard and Custom Object Types.
- Apex—an instance of an Apex class. (Most often a custom class.) See Custom Apex Class Types.
- Collection—a collection of any of the other types. See Collection Types.
Returning Apex Objects
Here’s an example of a controller that returns a collection of
custom Apex
objects.
When an instance of an Apex class is returned from a server-side action, the instance is serialized to JSON by the framework. Only the values of public instance properties and methods annotated with @AuraEnabled are serialized and returned.
For example, here’s a simple “wrapper” Apex class that contains a few details for an
account record. This class is used to package a few details of an account record in a
serializable format.
