Architecture Overview

JD.Domain Suite architecture and package organization.

System Design

JD.Domain follows a modular, layered architecture:

Core Layer

  • Abstractions - Contracts and primitives (Result, DomainError, DomainManifest)
  • Modeling - Fluent DSL for domain definitions
  • Configuration - EF Core configuration DSL
  • Rules - Business rules DSL
  • Runtime - Rule evaluation engine

Integration Layer

  • EFCore - Entity Framework Core integration
  • AspNetCore - ASP.NET Core middleware and filters
  • Validation - Shared validation contracts

Generation Layer

  • Generators.Core - Base generator infrastructure
  • DomainModel.Generator - Rich domain type generator
  • FluentValidation.Generator - Validator generator

Tooling Layer

  • Snapshot - Domain snapshot serialization
  • Diff - Change detection and comparison
  • Cli - Command-line tools
  • T4.Shims - T4 template integration

Package Dependencies

Abstractions (netstandard2.0)
    ├─ Modeling → Configuration → EFCore
    ├─ Rules → Runtime → AspNetCore
    ├─ Generators.Core → DomainModel.Generator
    ├─ Generators.Core → FluentValidation.Generator
    └─ Snapshot → Diff → Cli

Design Goals

  1. Opt-in - No forced dependencies or base classes
  2. Modular - Use only what you need
  3. Deterministic - Stable, predictable outputs
  4. Extensible - Clear extension points
