\[ \] ❌ Skip input validation "for internal use" - \[ \] ❌ Use direct SQL queries instead of Eloquent ORM or Query Builder - \[ \] ❌ Ignore error handling in background jobs (always try-catch) - \[ \] ❌ Log sensitive information (passwords, API keys, personal data) - \[ \] ❌ Skip database indexes for frequently queried columns - \[ \] ❌ Use synchronous operations for long-running tasks (use Task::add()) - \[ \] ❌ Hardcode configuration values (use config() method) - \[ \] ❌ Skip permission checks in controllers - \[ \] ❌ Ignore rate limiting for external APIs - \[ \] ❌ Use non-existent methods like `queueTask()` (use Task::add() directly) - \[ \] ❌ Use incorrect Task::add() parameters (no 'uuid' parameter needed) - \[ \] ❌ Call non-existent helper methods like `getJobParameter()` #### **✅ Best Practices** - \[ \] ✅ Use environment variables for sensitive configuration (.env file) - \[ \] ✅ Validate all inputs with Laravel Validator rules - \[ \] ✅ Use Laravel's built-in security features (CSRF, XSS protection) - \[ \] ✅ Implement comprehensive error handling with try-catch blocks - \[ \] ✅ Use structured logging with context (service\_uuid, action, data) - \[ \] ✅ Optimize database queries and add indexes on foreign keys - \[ \] ✅ Use Task::add('ModuleJob', 'Module', $data, $tags) with correct parameters - \[ \] ✅ Make configuration flexible using config.php and .env - \[ \] ✅ Implement proper authorization checks in all controller methods - \[ \] ✅ Handle external service failures gracefully with retries - \[ \] ✅ Follow the real API methods from actual module classes - \[ \] ✅ Use correct Task::add() parameters: $data must contain 'module' and 'method' only, no 'uuid' - \[ \] ✅ Always call setProvisionStatus('processing') before queueing tasks - \[ \] ✅ Store service data using setProvisionData() method - - - - - - **Remember**: A well-designed module is secure, performant, maintainable, and provides excellent user experience. Take time to plan, implement best practices, and thoroughly test before deployment.
