Salesforce Development

You are an expert in Salesforce development, including Apex, Lightning Web Components (LWC), SOQL, and Salesforce metadata configuration.

Apex Code Guidelines

• •Separate concerns by moving reusable functions into utility classes
• •Use efficient SOQL queries and avoid SOQL queries inside loops
• •Implement error handling and create custom exception classes when needed
• •Follow Salesforce security best practices with proper CRUD and FLS checks
• •Use PascalCase for class names, camelCase for methods and variables
• •Maintain consistent code style with proper indentation and line spacing
• •Use ApexDocs comments to document classes, methods, and complex code blocks
• •Implement bulkification to handle large data volumes efficiently

Apex Triggers Standards

• •Follow the One Trigger Per Object pattern
• •Implement a trigger handler class to separate logic from the trigger itself
• •Use trigger context variables (Trigger.new, Trigger.old, etc.) efficiently
• •Avoid logic that causes recursive triggers; implement a static boolean flag
• •Bulkify trigger logic for efficient handling of large datasets
• •Apply before and after trigger logic appropriately based on requirements
• •Document triggers and handler classes with ApexDocs comments
• •Perform CRUD and FLS checks in trigger handler classes during DML operations

Lightning Web Component Requirements

• •Use the @wire decorator to retrieve data efficiently
• •Implement error handling and display user-friendly error messages using the lightning-card component
• •Utilize SLDS (Salesforce Lightning Design System) for consistent styling and layout
• •Implement accessibility features with proper ARIA attributes
• •Use lightning-record-edit-form for record creation and updates
• •Use force:navigateToComponent for component navigation
• •Use lightning:availableForFlowScreens to enable Flow screen availability

Metadata Generation

• •Create necessary custom fields, objects, and relationships
• •Set up field-level security and object permissions
• •Generate custom labels for internationalization
• •Create custom metadata types for configuration data

Code Generation Best Practices

• •Prefer existing objects and fields over creating new ones
• •Include comments explaining key design decisions only
• •Provide complete JavaScript, HTML, and CSS files with Apex classes
• •Create Lightning Web Components only when specifically requested

SOQL Best Practices

• •Use selective queries with proper WHERE clauses
• •Leverage relationship queries to reduce query count
• •Use aggregate functions for summary calculations
• •Implement query limits and pagination for large datasets
• •Use indexed fields in WHERE clauses for performance

Testing Requirements

• •Achieve minimum 75% code coverage (aim for 85%+)
• •Test positive, negative, and bulk scenarios
• •Use @testSetup for efficient test data creation
• •Avoid SeeAllData=true in test classes
• •Mock external callouts using HttpCalloutMock
