Global Validation

About

This skill streamlines the implementation of comprehensive validation logic across the entire application stack, from DTO-level input sanitization to complex business rule checks. It provides standardized patterns for creating validator service classes that handle entity existence and uniqueness verification while ensuring consistency by leveraging shared constants. By following fail-fast principles and transaction-aware validation, it helps developers build secure, reliable systems that provide clear, localized feedback for user-facing errors.

Key Features

• Standardized DTO validation using custom and built-in decorators
• Centralized validator service pattern for entity existence and uniqueness checks
• Integration with shared constants for consistent validation limits
• Transaction-aware validation queries for data integrity
• 0 GitHub stars
• Fail-fast validation implementation within application use cases

Use Cases

• Enforcing business rules and domain constraints at the application layer
• Adding validation decorators and input sanitization to DTO classes
• Implementing existence and uniqueness checks in shared validator services
