Book Review: Clean Architecture

Quick Summary

• Title: Clean Architecture: A Craftsman's Guide to Software Structure and Design
• Author: Robert C. Martin (Uncle Bob)
• Rating: 4.5/5
• Reading Time: ~8 hours
• Target Audience: Mid to Senior level developers

What I Liked

1. Clear Principles

The book excellently explains the SOLID principles:

• Single Responsibility
• Open-Closed
• Liskov Substitution
• Interface Segregation
• Dependency Inversion

2. Practical Examples

// Bad: High coupling
class OrderProcessor {
    private MySQLDatabase db;
    
    public void processOrder(Order order) {
        db.save(order);
    }
}

// Good: Dependency Inversion
class OrderProcessor {
    private DatabaseInterface db;
    
    public OrderProcessor(DatabaseInterface db) {
        this.db = db;
    }
    
    public void processOrder(Order order) {
        db.save(order);
    }
}

3. Modern Relevance

Despite being written before the rise of microservices and serverless, the principles apply perfectly to modern architectures.

What Could Be Better

1. More JavaScript/TypeScript examples
2. Cloud architecture considerations
3. Microservices-specific guidance

Key Takeaways

1. Architecture is about boundaries
2. Dependencies should point inward
3. Business rules should be isolated
4. Framework decisions are details

Should You Read It?

Yes, if you:

• Want to understand architectural principles
• Need to make better system design decisions
• Work on large-scale applications

No, if you:

• Are just starting programming
• Need framework-specific guidance
• Want quick, practical solutions
