Import Apex Methods

Use default import syntax in JavaScript to import an Apex method via the @salesforce/apex scoped packages.

Syntax 

 
1import apexMethodName from "@salesforce/apex/namespace.classname.apexMethodReference";
  • apexMethodName—A symbol that identifies the Apex method.
  • apexMethodReference—The name of the Apex method to import.
  • classname—The name of the Apex class.
  • namespace—If the class is in the same namespace as the component, don’t specify a namespace. If the class is in a managed package, specify the namespace of the managed package.

Usage 

When an Apex class name changes outside of the JavaScript source file, the class name is automatically updated in the JavaScript source file. Method and argument name changes aren’t updated in the JavaScript source file.
