Description
Transition from Rails' traditional MVC trio to layered abstractions with state machines, workflows, and AI integrations and evolve your codebase into a flexible, future-ready applicationFree with your book: DRM-free PDF version + access to Packt's next-gen Reader*Key Features:- Understand Rails' architectural patterns, their strengths and limits- Organize business logic in Rails apps when the default MVC approach is insufficient- Introduce abstractions to integrate and manage AI features effectively- Purchase of the print or Kindle book includes a free PDF eBookBook Description:Rails accelerates web development with its convention-over-configuration principle and MVC pattern. But as your app grows, that simplicity can turn into tangled complexity, making it harder to maintain and extend. The second edition of Layered Design for Ruby on Rails Applications helps tackle this challenge head on, guiding you toward a more scalable and maintainable architecture.Written by a seasoned software engineer and open source contributor to Ruby on Rails, this updated edition refines the proven techniques from the first edition and introduces timely new topics that reflect today's development challenges. You'll dive deeper into state machines and workflows, learning how to identify, embed, and eventually isolate them for clarity and resilience. You'll also explore the exciting frontier of abstractions in the AI era, treating LLMs as APIs, structuring agent layers, and integrating third-party libraries to keep your AI features organized and testable.By embracing layered abstractions, you'll not only reduce complexity but also improve your ability to adapt to change - whether adding new features, scaling systems, or weaving AI capabilities into your applications.By the end of the book, you'll be equipped to design clean, extensible, and future-ready Rails applications.*Email sign-up and proof of purchase requiredWhat You Will Learn:- Get to grips with Rails' core components and its request/response cycle- See how Rails' convention-over-configuration principle shapes development- Explore patterns for flexibility, extensibility, and testability in Rails- Identify and refactor Rails anti-patterns for improved maintainability- Implement patterns to tame bloated models and messy views- Transition from implicit to explicit state machines and workflows- Treat LLMs as APIs and extract agent layers for AI-powered features- Use third-party libraries and RAG strategies to manage AI context effectivelyWho this book is for:This book is for Rails developers who want to manage and master the growing complexity of their applications. Whether you're extending an MVP into a robust system, scaling a monolithic app, or exploring AI-driven features, this book equips you with the design patterns and abstractions to keep your codebase future-proof. A solid understanding of Rails principles is required, and prior experience building Rails apps will help you put these patterns into practice.Table of Contents- Rails as a Web Application Framework- Active Models and Records- More Adapters, Less Implementations- Rails Anti-Patterns- When Rails Abstractions Are Not Enough- Data Layer Abstractions- State Transitions and Workflows- Handling User Input Outside of Models- Pulling Out the Representation Layer- Authorization Models and Layers- Crafting the Notifications Layer- Better Abstractions for HTML Views- Abstractions in the AI Era- Configuration as a First-Class Application Citizen- Cross-Layers and Off-Layers- Appendix: Gems and Patterns
