Best Practices
Development Standards
- Follow Apex coding conventions and style guide
- Use bulkified code patterns (no SOQL/DML in loops)
- Implement proper exception handling
- Write comprehensive test classes (75%+ coverage)
- Use descriptive variable and method names
- Document complex business logic
Governor Limits
- Maximum 100 SOQL queries per transaction
- Maximum 150 DML statements per transaction
- Maximum 10,000 records per SOQL query
- Maximum 50,000 records total retrieved
- Use @future for async processing
- Implement batch Apex for large data volumes
Security Best Practices
- Use "with sharing" keyword for classes
- Implement field-level security checks
- Validate user input and sanitize data
- Use parameterized queries to prevent SOQL injection
- Follow principle of least privilege
- Regular security reviews and audits
Lightning Best Practices
- Use cacheable Apex methods with @wire
- Implement proper error handling
- Minimize server round trips
- Use base Lightning components
- Follow Salesforce Lightning Design System (SLDS)
- Optimize component performance
Anti-Patterns
Code Smells
- SOQL/DML statements inside loops
- Hard-coded IDs and values
- Missing null checks
- Recursive trigger calls
- God classes with too many responsibilities
- Missing test coverage
Design Issues
- Tight coupling between components
- No separation of concerns
- Monolithic trigger code
- Missing bulk processing support
- Direct DML operations in triggers
- No error handling strategy
Performance Issues
- Unnecessary SOQL queries
- Processing too many records synchronously
- Missing indexes on frequently queried fields
- Not using selective queries
- Inefficient data structures
- Missing view state optimization
