Can I use this for custom domain-specific errors?

Absolutely. It provides examples and patterns for creating custom Business Rule Exceptions that extend the base NestJS HttpException.

Does this skill handle database-specific errors?

Yes, it specifically handles Prisma ORM errors such as P2002 (unique constraint violations) and P2025 (record not found), mapping them to proper HTTP status codes.

How do I apply the generated filter to my whole app?

The skill provides the specific line of code needed to register the filter using app.useGlobalFilters() within your NestJS main.ts file.

Is the generated code secure for production use?

Yes, the skill follows security best practices by ensuring stack traces are never exposed to the client and only logging critical server-side errors.

API開発

Generates robust global exception filters and custom business logic exceptions for standardized NestJS error handling.

This skill automates the implementation of centralized error-handling logic in NestJS applications, ensuring a consistent API response format across your entire project. It generates production-ready Global Exception Filters that intelligently handle standard HTTP exceptions, map specific Prisma ORM errors to appropriate status codes, and implement secure logging practices. By distinguishing between client-side mistakes and server-side failures, it helps developers maintain observability while preventing the exposure of sensitive stack traces in production environments.
