Apex in Lightning Web Components
We’ve covered the benefits of Lightning Data Service and how to use it, but sometimes, neither the lightning-record-*-form components nor the LDS wire adapters and functions suit a particular use case.
Use Apex Methods with Lightning Web Components
An Apex method used in a Lightning web component must be static, public or global, and annotated with @AuraEnabled immediately before the method definition. The @AuraEnabled annotation makes the Apex method available to Lightning components (both Lightning web components and Aura components).
Call Apex Methods from LWC
There are two ways to interact with Apex methods from Lightning web components: either wire the method or call the method imperatively. Let’s consider both approaches.
Call Apex Imperatively
An alternative to calling Apex with @wire is to call Apex imperatively. Call Apex imperatively when you need to control the invocation of read operations, and when you modify records. To call Apex imperatively, you invoke Apex one time from a component’s JavaScript file instead of delegating control to the Lightning Web Components engine.
Deploy a Lightning Web Component That Lists Records in a Table
Let’s work with an example that displays a list of existing Accounts in a lightning-datatable. We’ll use Apex and @wire to retrieve the records.
