#Salesforce Admin #Salesforce Developer #Apex How would you build a Lightning Web Component that retrieves and displays Account records using an Apex controller? Explain Apex methods, SOQL queries, the @wire decorator, error handling, and enforcement of record-level, object-level, and field-level security.

Hi @Rakesh Goud You can retrieve and display Account records in LWC using an Apex controller.
Here are the key steps:
- Apex Class: Create an Apex method with @AuraEnabled(cacheable=true).
- SOQL: Query the required Account fields, such as Id, Name, and Industry.
- LWC JavaScript: Import the Apex method and use @wire to fetch records.
- LWC HTML: Display the Account records using for:each or lightning-datatable.
- Error Handling: Handle both data and error in the wire response.
- Security: Use with sharing for record-level access and WITH USER_MODE in SOQL for object-level and field-level permissions.
A few important points:
- Use @wire with cacheable Apex methods for read-only data.
- Use imperative Apex when you need to control when the method runs.
- For simple record retrieval, Lightning Data Service or UI API may be a better choice without Apex.
Useful Salesforce Documentation:
My suggestion is to start with a simple Account list using @wire, then add a datatable and proper error handling.
Hope this helps!
