Salesforce Development

Patterns

Lightning Web Component with Wire Service

Use @wire decorator for reactive data binding with Lightning Data Service or Apex methods. @wire fits LWC's reactive architecture and enables Salesforce performance optimizations.

Bulkified Apex Trigger with Handler Pattern

Apex triggers must be bulkified to handle 200+ records per transaction. Use handler pattern for separation of concerns, testability, and recursion prevention.

Queueable Apex for Async Processing

Use Queueable Apex for async processing with support for non-primitive types, monitoring via AsyncApexJob, and job chaining. Limit: 50 jobs per transaction, 1 child job when chaining.
