🌐 FunqTypes.AspNet - Helpers for Asp.Net

🎯 What is FunqTypes?

FunqTypes is a set of functional types and helpers for .NET that brings null-safety, error handling and composition to C# applications. It provides:

  • ✅ Result<T> type - Monadic error handling with Ok/Fail or Gotcha/Oops alternative aliases
  • ✅ Option<T> type - Null-safe optional values with Some/None or Yeah/Nah alternative aliases
  • ✅ LINQ & FP Support - Fluent mappings, binding, filtering
  • ✅ Zero Overhead - Efficient readonly record struct implementation

Standard Usage (Default 200 OK)

[HttpGet("{id}")]
public async Task<IActionResult> GetAccount(int id)
{
    return await GetAccountById(id).ToActionResultAsync();
}
  • Returns 200 OK on success.
  • Returns 400 Bad Request on failure.

201 Created for POST Requests

[HttpPost]
public async Task<IActionResult> CreateAccount([FromBody] CreateAccountRequest request)
{
    return await CreateAccount(request).ToActionResultAsync(HttpStatusCode.Created);
}
  • Returns 201 Created on success.
  • Returns 400 Bad Request on failure.

Custom Error Mapping with HttpStatusCode

private static HttpStatusCode MapErrorToStatusCode(ValidationError error) =>
    error.Code switch
    {
        "NOT_FOUND" => HttpStatusCode.NotFound,
        "INVALID_INPUT" => HttpStatusCode.UnprocessableEntity,
        "UNAUTHORIZED" => HttpStatusCode.Unauthorized,
        _ => HttpStatusCode.BadRequest
    };

Then, use it in the controller:

[HttpPut("{id}")]
public async Task<IActionResult> UpdateAccount(int id, [FromBody] UpdateAccountRequest request)
{
    return await UpdateAccount(id, request).ToActionResultAsync(HttpStatusCode.OK, MapErrorToStatusCode);
}
  • 404 Not Found for NOT_FOUND
  • 422 Unprocessable Entity for INVALID_INPUT
  • 401 Unauthorized for UNAUTHORIZED
  • 400 Bad Request for other errors
