ilandev.AspNetCore.ExceptionHandler

Customizable exception mapping middleware for ASP.NET Core. Allows you to specify custom response lambdas for specific exception types.

Usage

1. Call builder.Services.AddExceptionHandlingMiddleware() and pass in a configuration action to configure the middleware.
2. Call app.UseExceptionHandlingMiddleware() after the call to app.UseRouting().

Examples

builder.Services.AddExceptionHandlingMiddleware(c => c
	.AddHandler<UserNotFoundException>(e => new ExceptionMapping
	{
		StatusCode = HttpStatusCode.BadRequest,
		Response = new
		{
			ErrorCode = "user_not_found"
		}
	})
);

// ...

app.UseExceptionHandlingMiddleware();

Any exceptions thrown of type UserNotFoundException (or any exceptions inheriting from this type) will cause the above-mentioned response to be written.
