Best Practices

1. Follow conventions - Adhere to established naming and structural patterns for consistency
2. Configure appropriately - Set up framework configuration that matches project requirements
3. Validate inputs - Always validate and sanitize inputs before processing
4. Handle errors gracefully - Implement comprehensive error handling and recovery
5. Document decisions - Comment configuration choices and non-obvious implementations
6. Test thoroughly - Write comprehensive tests for all functionality
7. Optimize performance - Profile and optimize critical paths
8. Maintain security - Follow security best practices and guidelines
9. Keep updated - Regularly update framework and dependencies
10. Monitor production - Implement logging and monitoring for production systems

Common Pitfalls

1. Incorrect configuration - Misconfiguration leads to unexpected behavior and bugs
2. Missing error handling - Not handling edge cases causes production issues
3. Poor performance - Not optimizing leads to scalability problems
4. Inadequate testing - Insufficient test coverage misses bugs
5. Security vulnerabilities - Not following security best practices exposes risks
6. Tight coupling - Poor architecture makes maintenance difficult
7. Ignoring warnings - Dismissing framework warnings leads to future problems
8. Outdated dependencies - Using old versions exposes security risks
9. No monitoring - Lack of observability makes debugging difficult
10. Inconsistent standards - Team inconsistency reduces code quality
