Late4dTrain.Domain.Abstractions

This library provides a set of abstractions for Domain-Driven Design elements such as Entities, Value Objects, and Aggregate Roots. These abstractions serve as the building blocks for your domain model and enforce key characteristics required by each element.

Installation

Install the library using the following command:

dotnet add package Late4dTrain.Domain.Abstractions

Usage

Here is an example of how you can use the library:

public class Customer : AggregateRoot<Guid, DomainEvent>
{
    public string Name { get; private set; }

    public Customer(string name)
    {
        Id = Guid.NewGuid();
        Name = name;
        Events.Add(new CustomerCreated(Id));
    }
}

public class CustomerCreated : DomainEvent
{
    public Guid CustomerId { get; }

    public CustomerCreated(Guid customerId)
    {
        CustomerId = customerId;
    }
}

In this example, Customer is an Aggregate Root that uses a Guid as an identifier and DomainEvent as its domain event type. When a new customer is created, a CustomerCreated is added to the list of domain events.

Entity

Entities are fundamental building blocks of domain-driven design. They are mutable objects with a consistent thread of identity. Here is a basic example of how to create an entity:

public class SampleEntity : Entity<Guid>
{
    public override Guid Id { get; protected set; } = Guid.NewGuid();

    // Additional properties and methods here...
}

In this example, SampleEntity is an entity with a unique identifier of type Guid

Value Object

Value objects are objects that we care about only because of their properties and the values those properties have. They don't have an identity, meaning two value objects with the same properties are considered equal. Here's an example:

public class SampleValueObject : IValueObject
{
    // Properties and methods here...
}

In this example, SampleValueObject is a value object.
