Nlabs.Result 9.0.0

NLabs.Result NuGet Package

Overview

The NLabs.Result package is designed to encapsulate the result of operations in .NET applications, offering a structured way to handle success and failure states with associated data or error messages. It is ideal for improving error handling and response consistency across various application layers.

Features

• Generic Result Type: Facilitates strong typing of the operation outcome, accommodating any data type.
• Error Handling: Enables capturing multiple error messages or detailed error structures using Dictionary<string, List<string>>, suitable for scenarios requiring detailed feedback.
• HTTP Status Code Integration: Aligns operation results with HTTP response standards, enhancing API development.
• Implicit Conversions: Streamlines result creation from data or errors through implicit conversion operators.

Getting Started

Installation

To integrate NLabs.Result into your project, install it via the NuGet package manager:

Install-Package NLabs.Result

Or through the .NET CLI:

dotnet add package NLabs.Result

Usage

• For a successful operation, instantiate a Result object with the desired data:

var successResult = new Result<string>("Operation successful.");

• Alternatively, leverage implicit conversion from data:

Result<string> result = "Operation successful.";

• For failures, create a Result object with an HTTP status code and error messages:

var errorResult = new Result<string>(400, new List<string> { "Error 1", "Error 2" });

• Or use implicit conversion from error details:

Result<string> result = (400, new List<string> { "Error 1", "Error 2" });

• For single error messages:

Result<string> result = (400, "Single error message");

• One error message return 400 status code

Result<string> result = Result<string>.Fail("Is fail!"); //return 400 status code

• Multiple error messages return 400 status code

Result<string> result = Result<string>.Fail(new List<string>() {"Is fail!","Is not unique!"}); //return 400 status code

• **For example, to return multiple validation errors for specific fields:

var errorDetails = new Dictionary<string, List<string>> 
{
    { "Email", new List<string> { "Invalid email format", "Email already in use" } },
    { "Password", new List<string> { "Password must be at least 6 characters long" } }
};

Result<string> result = (400, errorDetails);

• **Extended Failure Method for Error Details
• In scenarios where detailed validation errors are required, you can use the following syntax:

Result<string> errorResult = Result<string>.Fail(400, new Dictionary<string, List<string>>
{
    { "Email", new List<string> { "Invalid email", "Email is already taken" } },
    { "Password", new List<string> { "Password must be stronger" } }
});
