Pandatech.ResponseCrafter

Introduction

ResponseCrafter is a comprehensive NuGet package for .NET 8+, specifically designed for enhanced exception handling and logging in ASP.NET applications. This package simplifies the process of handling standard and custom exceptions by crafting detailed error responses suitable for both development and production environments.

Features

• Custom Exception Handling: Streamlines the process of managing both standard HTTP exceptions and custom exceptions.
• Detailed Error Responses: Generates verbose error messages, including stack traces for in-depth debugging in development environments.
• Environment-Sensitive Logging: Offers a class PandaExceptionHandler which can be configured for message verbosity. In production environments, only the exception type and message are logged. In development environments, the entire exception is logged, including the stack trace.
• Frontend-Friendly Error Messages: Encourages the use of snake_case in error messages, facilitating easier integration with frontend localization systems.
• Organized/Readable and standardized error responses: Provides a standardized error response format for all exceptions, making it easier for frontend applications to parse and display error messages. The error response format is shown below:

{
  "TraceId": "0HMVFE0A284AM:00000001",
  "Instance": "POST - 164.54.144.23:443/users/register",
  "StatusCode": 400,
  "Type": "BadRequestException",
  "Errors": {
    "email": "email_address_is_not_in_a_valid_format",
    "password": "password_must_be_at_least_8_characters_long"
  },
  "Message": "the_request_was_invalid_or_cannot_be_otherwise_served."
}
