Designing Extensible Behavior – From Strategy to Plugin Architectures and Configuration-Driven Logic by Rainer Sanchez Navarro
Modern software must adapt—quietly, safely, and often long after it ships. Extensibility is no longer a luxury; it's a requirement. This book is a practical guide to designing systems whose behavior grows without friction and evolves without rewrites.
From the foundations of the Strategy pattern to robust plugin systems and configuration-driven logic, this book walks through the architectural principles that make software flexible and maintainable. Each chapter focuses on pragmatic techniques, real-world patterns, and clear examples that show how to introduce variability, decouple logic, and open your systems to extension while keeping complexity under control.
You will learn how
Build systems around well-defined contracts and interchangeable behaviors
Move from basic strategies to fully modular plugin architectures
Use configuration as a first-class tool to modify behavior at runtime
Avoid common pitfalls when introducing extensibility into existing codebases
Structure your application to support growth, integrations, and evolving requirements
