ATK.Command.Communication.Models

A lightweight .NET Standard 2.1 class library providing reusable data models for web API communication. This library offers essential models for building standardized API responses, handling pagination, managing notifications, and transferring file data.

Features

• ApiResponse - Generic API response wrapper with status, data, message, and notifications support
• Paging - Configurable pagination request model with filter, skip, and take parameters
• PaginationResponse - Generic pagination response model for paginated data
• Notification - Notification model with severity levels and factory methods (Success, Info, Warning, Error)
• FileModel - File transfer model with support for both binary and Base64-encoded content

Installation

Install the NuGet package:

dotnet add package ATK.Command.Communication.Models

Or using the NuGet Package Manager:

Install-Package ATK.Command.Communication.Models

Quick Start

ApiResponse

The ApiResponse<T> class provides a standardized API response format with status tracking and notification support:

using ATK.Command.Communication.Models;

// Create a successful response
var response = new ApiResponse<User>
{
    Status = "success",
    Data = user,
    Message = "User retrieved successfully"
};

// Check response status
if (response.IsSuccess)
{
    // Handle success
}

// Add notifications
response.Notifications.Add(Notification.Info("Data loaded from cache"));

Pagination

Use the Paging model for pagination requests and PaginationResponse<T> for responses:

// Create a paging request
var paging = new Paging
{
    Filter = "active",
    Skip = 0,
    Take = 20
};

// Create a paginated response
var response = new PaginationResponse<User>
{
    Total = 150,
    Items = users
};

Notifications

The Notification class provides factory methods for creating different severity levels:

// Create notifications using factory methods
var success = Notification.Success("Operation completed", "Success", new { userId = 123 });
var info = Notification.Info("This is informational", "Info");
var warning = Notification.Warning("Please review this", "Warning");
var error = Notification.Error("An error occurred", "Error");

// Add to response
response.Notifications.AddRange(new[] { success, info });

File Transfer

The FileModel class supports both binary and Base64-encoded file content:

var fileModel = new FileModel
{
    Name = "document.pdf",
    ContentType = "application/pdf",
    Content = fileBytes
};

// Convert to Base64 for transmission
fileModel.ToBase64();

// Convert back from Base64
fileModel.FromBase64();
