NestJS Error Handling

What problem does it solve?

This Skill addresses the challenge of inconsistent and potentially insecure error handling in NestJS applications by providing a standardized approach to global exception filters and error formatting.

Core Features & Use Cases

• Global Exception Filtering: Centralizes error handling logic for consistent JSON responses across the application.
• Platform Agnostic Error Handling: Utilizes HttpAdapterHost to avoid direct dependency on Express or Fastify types.
• Standardized Error Structure: Enforces a consistent format for API error responses, preventing information leakage.
• Use Case: Ensure all API errors, from validation failures to internal server errors, return a predictable JSON structure, enhancing client-side integration and security.

Quick Start

Implement a global exception filter in your NestJS application to standardize error responses.
