ErrorLib.AspNetCore

๐ŸŒ Robust global exception handling middleware for ASP.NET Core built on top of ErrorLib.Core.

ErrorLib.AspNetCore provides seamless integration for standardized error handling, exception-to-HTTP mapping, and structured result responses in ASP.NET Core applications.

โœจ Features

  • โœ… Global exception capturing middleware
  • ๐Ÿ”„ Unified JSON error responses
  • ๐Ÿ”— Integration with Result, ErrorResult, ValidationErrorResult
  • ๐Ÿง  Customizable IExceptionMapper
  • ๐Ÿ”Œ Pluggable ILogger support (Console or Microsoft.Extensions.Logging)
  • ๐Ÿงช Supports .NET 6, .NET 7, .NET 8

๐Ÿ“ฆ Installation

Install both core and ASP.NET Core-specific packages:

dotnet add package ErrorLib.Core
dotnet add package ErrorLib.AspNetCore
๐Ÿš€ Usage
1. Register Required Services (in Program.cs):

builder.Services.AddSingleton<ILogger, ConsoleLogger>(); // or MicrosoftLoggerAdapter
builder.Services.AddSingleton<IExceptionMapper, DefaultExceptionMapper>();
You can create and register your own IExceptionMapper to customize behavior.

2. Enable Middleware:

app.UseCustomExceptionHandler();
๐Ÿงช Example JSON Error Response
json

{
  "isSuccess": false,
  "message": "Something went wrong",
  "errorCode": "INTERNAL_SERVER_ERROR",
  "statusCode": 500,
  "traceId": "abc123",
  "validationErrors": []
}
๐Ÿง  Custom Exception Mapping
To define how exceptions map to status codes and messages:


public class MyExceptionMapper : IExceptionMapper
{
    public int MapStatusCode(Exception ex) =>
        ex switch
        {
            NotFoundException => 404,
            BusinessException => 409,
            _ => 500
        };

    public string MapMessage(Exception ex) => ex.Message;
    public string MapErrorCode(Exception ex) => "GENERIC_ERROR";
}
๐Ÿ”Œ Logging Options
Use ILogger interface provided by ErrorLib.Core.


ILogger logger = new ConsoleLogger();
logger.LogError("Something failed", ex);
Or integrate with ASP.NET Core:


ILogger logger = new MicrosoftLoggerAdapter(yourInjectedLogger);
