Pros of CleanArchitecture (Jason Taylor)

• More comprehensive, including features like authentication, authorization, and API versioning
• Utilizes modern .NET features and patterns, such as Minimal APIs and Vertical Slice Architecture
• Includes a robust testing suite with examples of unit, integration, and functional tests

Cons of CleanArchitecture (Jason Taylor)

• May be overwhelming for beginners due to its complexity and extensive feature set
• Opinionated approach might not fit all project requirements or team preferences
• Steeper learning curve compared to simpler implementations

Code Comparison

CleanArchitecture (Jason Taylor):

public sealed class CreateTodoItemCommandHandler : IRequestHandler<CreateTodoItemCommand, int>
{
    private readonly IApplicationDbContext _context;

    public CreateTodoItemCommandHandler(IApplicationDbContext context)
    {
        _context = context;
    }

CleanArchitecture (Ardalis):

public class CreateProjectCommandHandler : IRequestHandler<CreateProjectCommand, int>
{
  private readonly IRepository<Project> _repository;

  public CreateProjectCommandHandler(IRepository<Project> repository)
  {
    _repository = repository;
  }

Both examples showcase similar command handler structures, but Jason Taylor's implementation uses a custom database context interface, while Ardalis' version utilizes a generic repository pattern.

Pros of eShopOnWeb

• More comprehensive e-commerce example with real-world scenarios
• Includes additional features like basket management and ordering
• Better documentation and explanations of architectural decisions

Cons of eShopOnWeb

• More complex and potentially overwhelming for beginners
• Less focused on clean architecture principles
• Harder to extract and apply to non-e-commerce projects

Code Comparison

CleanArchitecture:

public class DeleteProjectCommand : IRequest
{
    public int Id { get; set; }
}

public class DeleteProjectCommandHandler : IRequestHandler<DeleteProjectCommand>
{
    private readonly IRepository<Project> _repository;

    public DeleteProjectCommandHandler(IRepository<Project> repository)
    {
        _repository = repository;
    }

eShopOnWeb:

public class CreateOrderCommand : IRequest<int>
{
    public string BuyerId { get; set; }
    public Address ShippingAddress { get; set; }
    public Address BillingAddress { get; set; }
    public List<OrderItemDTO> Items { get; set; }
}

public class CreateOrderCommandHandler : IRequestHandler<CreateOrderCommand, int>
{
    private readonly IOrderRepository _orderRepository;

Both repositories demonstrate CQRS pattern usage, but eShopOnWeb's example is more complex, reflecting real-world e-commerce scenarios. CleanArchitecture focuses on simpler, more generic implementations that are easier to adapt to various project types.

Pros of clean-architecture-manga

• More comprehensive implementation of Clean Architecture principles
• Includes additional features like CQRS and Event Sourcing
• Provides a more detailed domain model and use cases

Cons of clean-architecture-manga

• Higher complexity, which may be overwhelming for beginners
• Steeper learning curve due to advanced concepts and patterns
• Less focus on simplicity and ease of understanding

Code Comparison

CleanArchitecture:

public class DeleteProjectHandler : ICommandHandler<DeleteProjectCommand, ProjectDto>
{
    private readonly IRepository<Project> _repository;
    public DeleteProjectHandler(IRepository<Project> repository) => _repository = repository;
    public async Task<ProjectDto> Handle(DeleteProjectCommand request, CancellationToken cancellationToken)
    {
        var projectToDelete = await _repository.GetByIdAsync(request.ProjectId);
        await _repository.DeleteAsync(projectToDelete);
        return new ProjectDto(projectToDelete.Id, projectToDelete.Name);
    }
}

clean-architecture-manga:

public sealed class CloseAccountUseCase : ICloseAccountUseCase
{
    private readonly IAccountRepository _accountRepository;
    private readonly IUnitOfWork _unitOfWork;
    public CloseAccountUseCase(IAccountRepository accountRepository, IUnitOfWork unitOfWork)
    {
        _accountRepository = accountRepository;
        _unitOfWork = unitOfWork;
    }
    public async Task<CloseAccountOutput> Execute(CloseAccountInput input)
    {
        var account = await _accountRepository.Get(input.AccountId);
        if (account == null) throw new AccountNotFoundException($"The account {input.AccountId} does not exist or is already closed.");
        account.Close();
        await _accountRepository.Update(account);
        await _unitOfWork.Save();
        return new CloseAccountOutput(account);
    }
}

Pros of EquinoxProject

• Implements Event Sourcing and CQRS patterns, providing a more comprehensive approach to domain-driven design
• Includes integration with Swagger for API documentation
• Offers a more extensive set of features, including identity management and JWT authentication

Cons of EquinoxProject

• More complex architecture, which may be overkill for smaller projects
• Steeper learning curve due to the additional patterns and technologies used
• Less frequently updated compared to CleanArchitecture

Code Comparison

CleanArchitecture:

public class DeleteToDoItemCommand : IRequest
{
    public int Id { get; set; }
}

EquinoxProject:

public class RegisterNewCustomerCommand : Command
{
    public Guid Id { get; private set; }
    public string Name { get; private set; }
    public string Email { get; private set; }
    public DateTime BirthDate { get; private set; }
}

The EquinoxProject example shows a more detailed command structure with additional properties, reflecting its focus on CQRS and event sourcing. CleanArchitecture's example is simpler, aligning with its more straightforward approach to clean architecture.

Pros of modular-monolith-with-ddd

• Implements a more comprehensive Domain-Driven Design (DDD) approach
• Provides a detailed example of modular monolith architecture
• Includes more advanced patterns like CQRS and Event Sourcing

Cons of modular-monolith-with-ddd

• More complex structure, potentially steeper learning curve
• Less focus on Clean Architecture principles
• May be overkill for smaller projects or teams new to DDD

Code Comparison

CleanArchitecture:

public class DeleteTodoItemCommand : IRequest
{
    public int Id { get; set; }
}

modular-monolith-with-ddd:

public class CreateMeetingGroupCommand : CommandBase<MeetingGroupId>
{
    public string Name { get; }
    public string Description { get; }
    public MeetingGroupLocation Location { get; }
}

The modular-monolith-with-ddd example shows a more detailed command structure with domain-specific types, while CleanArchitecture uses a simpler approach with primitive types.

Both repositories offer valuable insights into structuring .NET applications, but they cater to different levels of complexity and architectural focus. CleanArchitecture provides a cleaner, more straightforward implementation of Clean Architecture principles, while modular-monolith-with-ddd offers a more comprehensive example of DDD and modular monolith patterns.

Pros of NorthwindTraders

• Implements a more comprehensive set of Clean Architecture principles
• Includes a broader range of features and technologies (e.g., CQRS, MediatR)
• Provides a more realistic and complex example of a business application

Cons of NorthwindTraders

• May be overwhelming for beginners due to its complexity
• Requires more setup and configuration to get started
• Has a steeper learning curve compared to CleanArchitecture

Code Comparison

NorthwindTraders:

public class CreateCustomerCommand : IRequest<int>
{
    public string Id { get; set; }
    public string CompanyName { get; set; }
    public string ContactName { get; set; }
}

CleanArchitecture:

public class CreateToDoItemCommand : IRequest<ToDoItemRecord>
{
    public string Title { get; set; } = string.Empty;
    public string Description { get; set; } = string.Empty;
}

Both repositories demonstrate the use of CQRS patterns, but NorthwindTraders shows a more complex command structure with additional properties, reflecting its more comprehensive approach to Clean Architecture principles.
