Global Error Handling

About

This skill establishes a robust error handling architecture within a NestJS environment by standardizing how exceptions are created, categorized, and thrown. It guides the implementation of custom exception classes that extend a base class, integrates with centralized exception codes, and ensures user-friendly responses through localized error messages. By enforcing fail-fast validation patterns and specific naming conventions, it helps maintain a predictable and maintainable codebase where errors are handled gracefully and consistently across controllers, use cases, and validators.
