Architecture Patterns

Master proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design to build maintainable, testable, and scalable systems.

When to Use This Skill

Designing new backend systems from scratch
Refactoring monolithic applications for better maintainability
Establishing architecture standards for your team
Migrating from tightly coupled to loosely coupled architectures
Implementing domain-driven design principles
Creating testable and mockable codebases
Planning microservices decomposition

Core Concepts

1. Clean Architecture (Uncle Bob)

Layers (dependency flows inward):

Entities: Core business models
Use Cases: Application business rules
Interface Adapters: Controllers, presenters, gateways
Frameworks & Drivers: UI, database, external services

Key Principles:

Dependencies point inward
Inner layers know nothing about outer layers
Business logic independent of frameworks
Testable without UI, database, or external services

2. Hexagonal Architecture (Ports and Adapters)

Components:

Domain Core: Business logic
Ports: Interfaces defining interactions
Adapters: Implementations of ports (database, REST, message queue)

Benefits:

Swap implementations easily (mock for testing)
Technology-agnostic core
Clear separation of concerns

3. Domain-Driven Design (DDD)

Strategic Patterns:

Bounded Contexts: Separate models for different domains
Context Mapping: How contexts relate
Ubiquitous Language: Shared terminology

Tactical Patterns:

Entities: Objects with identity
Value Objects: Immutable objects defined by attributes
Aggregates: Consistency boundaries
Repositories: Data access abstraction
Domain Events: Things that happened

# Architecture Patterns

Master proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design to build maintainable, testable, and scalable systems.

Daftar alat adalah petunjuk metadata, bukan kompatibilitas teruji. Prompt adalah saran.

Mulai dengan tugas kecil

1Baca sumber dan pastikan masukan, keluaran, dependensi, serta izin.
2Minta rencana dari agent. Setujui pengaturan dan biaya sebelum uji terisolasi.
3Periksa hasil dan berkas yang berubah. Laporkan hanya yang dijalankan dan simpan revisi sumber.

Periksa dependensi, kunci API, dan biaya layanan pihak ketiga pada sumber. Repositori publik tidak berarti semua layanan gratis.
