Application Architecture

This section covers fundamental application architecture patterns and design principles for building scalable, maintainable software systems.

Topics Covered

🏗️ Core Patterns

• Microservices Architecture - Decomposing applications into small, independent services

• Getting Started with Microservices - Building microservices with shared TypeScript packages and GitLab registry

• Domain-Driven Design - Aligning software design with business domains

• MVC Without View Pattern - Backend-focused MVC adaptation for API services

Coming Soon

📐 Additional Patterns

• Clean Architecture - Ports and adapters pattern with dependency inversion

• Hexagonal Architecture - Isolating core business logic from external concerns

• Layered Architecture - Traditional N-tier architecture approach

• CQRS (Command Query Responsibility Segregation) - Separating reads from writes

• Modular Monolith - Well-structured monolith with clear module boundaries

🎯 Specialized Patterns

• Backend for Frontend (BFF) - API optimization for different client types

• Micro-frontends - Frontend decomposition strategies

• Component Design Systems - Atomic design principles and implementation

Key Principles

• Separation of Concerns - Clear boundaries between different responsibilities

• Single Responsibility - Each component has one reason to change

• Dependency Inversion - Depend on abstractions, not implementations

• Loose Coupling - Minimize dependencies between components

• High Cohesion - Related functionality grouped together

When to Use

Choose the right pattern based on:

• Team size and structure

• System complexity

• Scalability requirements

• Domain understanding

• Operational capabilities

• Technology constraints
