Learn Software Architecture - Patterns & Principles for Modern Systems

Master software architecture from foundational design patterns to advanced distributed system patterns. Learn clean architecture, microservices, domain-driven design, CQRS, event sourcing, and more with practical TypeScript examples. Build systems that are scalable, maintainable, and resilient.

Prerequisites

Before diving into software architecture, you should have solid experience with TypeScript or JavaScript and be familiar with object-oriented programming concepts. Experience with backend development (Node.js, Express) is recommended.

Frequently Asked Questions

What is software architecture?

Software architecture is the high-level structure of a software system, defining how components are organized, how they interact, and the principles guiding their design. It encompasses decisions about technology choices, design patterns, data flow, and system boundaries that impact scalability, maintainability, and performance of the entire application.

What is the difference between clean architecture and hexagonal architecture?

Clean architecture and hexagonal architecture both enforce separation of concerns and dependency inversion, but differ in their conceptual models. Clean architecture uses concentric circles with entities at the core, surrounded by use cases, interface adapters, and frameworks. Hexagonal architecture (ports and adapters) focuses on ports for input/output and adapters that connect to external systems. In practice, both achieve similar goals of keeping business logic independent from infrastructure.

When should you use microservices vs monolith?

Start with a monolith when your team is small, the domain is not well understood, or you need to move quickly. Consider microservices when you have independent teams that need to deploy separately, different scaling requirements for different parts of the system, or when a modular monolith has become difficult to maintain. Many successful companies start with a monolith and gradually extract microservices as needed.

What are the most important design patterns?

The most important design patterns for modern software development include creational patterns like Factory and Builder, structural patterns like Adapter and Decorator, and behavioral patterns like Observer and Strategy. Beyond GoF patterns, architectural patterns such as Repository, Dependency Injection, CQRS, and Event Sourcing are essential for building scalable, maintainable applications with clean separation of concerns.
