Aspireng.Domain

Purpose: Pure domain building blocks that remain stable across microservices:

  • Base entity contract (BaseEntity)
  • Repository abstraction (IRepository<T>)
  • Specification pattern (ISpecification<T>, SortDescriptor<T>)

No infrastructure or framework dependencies. Keep this package small, stable, and free of runtime side-effects.

Contents

  • Entities/BaseEntity.cs – common entity Id + optional concurrency token.
  • Abstractions/IRepository.cs – storage-agnostic repository contract.
  • Abstractions/ISpecification.cs – composable, provider-friendly query description.
  • Abstractions/SortDescriptor.cs – ordering rules for specifications.

Design Guidelines

  • DDD location: Repository abstractions live in the domain layer; concrete implementations live in Infrastructure.
  • Expressions only: ISpecification<T>.Criteria is an Expression<Func<T,bool>> to allow EF translation or in-memory evaluation.
  • No ad-hoc SQL: Avoid string queries; introduce named specifications instead.
  • Portability: BaseEntity.Id is string to play nicely with files, SQL, memory, etc.

Example

using System.Linq.Expressions;
using Aspireng.Domain.Abstractions;
using Aspireng.Domain.Entities;

public sealed class CreatedTodaySpec<T> : ISpecification<T> where T : BaseEntity, IHasCreatedAt
{
    public Expression<Func<T, bool>>? Criteria { get; } =
        x => x.CreatedAt.Date == DateTimeOffset.UtcNow.Date;

    public IReadOnlyList<SortDescriptor<T>> OrderBy { get; } =
        new[] { new SortDescriptor<T>(x => x.CreatedAt, ascending: false) };

    public int? Skip { get; } = null;
    public int? Take { get; } = 100;
}

What not to put here

  • No EF Core types, DbContexts, file IO, HTTP, caching, logging, or DI.
  • No microservice-specific domain entities. Each service owns its domain models.

Versioning

  • Semantic Versioning (SemVer). Avoid breaking the repository/specification surface.
  • Add capabilities via new interfaces or extension methods when possible.
