@AuraEnabled Methods
By the end of this lesson, you'll be able to:
- Mark an Apex method as callable from an LWC using @AuraEnabled
- Explain why the method must be public or global and static
- Recognize the annotation-based exposure pattern from Module 13
Prerequisites: "Why Apex Needs to Talk to the UI"
Marking a method as callable
public class AccountController {
@AuraEnabled
public static List<Account> getAccounts() {
return [SELECT Id, Name FROM Account];
}
}@AuraEnabled above the method is exactly Module 13's annotation pattern — metadata telling the platform "this method may be called from a Lightning Web Component," without changing what the method's own code actually does.
Why public/global and static
@AuraEnabled
public static List<Account> getAccounts() { ... } // correct shape
@AuraEnabled
private List<Account> getAccounts() { ... } // will NOT work — private, and not staticAn @AuraEnabled method must be public (or global, for methods exposed even outside the org, e.g. in a managed package) and static — the LWC framework calls it directly on the class, the same way TaxCalculator.applyVat(...) was called directly in Module 10, never on a specific object instance.
Exposing a parameterized method
public class AccountController {
@AuraEnabled
public static List<Account> searchAccountsByName(String searchTerm) {
return [SELECT Id, Name FROM Account WHERE Name LIKE :('%' + searchTerm + '%')];
}
}Parameters work exactly like any other method (Module 9) — the LWC's JavaScript passes the argument when it calls into Apex, and everything from Module 20's bind-variable safety still applies unchanged.
Exercise
Add @AuraEnabled to expose this method to an LWC, correcting anything else needed to make it callable.
Show hint
It needs the annotation, and must be public and static.

Summary
@AuraEnabled is the annotation that exposes an Apex method to be called from an LWC — the exact "attach metadata above a method" pattern Module 13 first introduced.
