Description

The Ruby on Rails framework boosts productivity by leveraging the convention-over-configuration principle and model-view-controller (MVC) pattern, enabling developers to build features efficiently. This initial simplicity often leads to complexity, making a well-structured codebase difficult to maintain. Written by a seasoned software engineer and award-winning contributor to many other open-source projects, including Ruby on Rails and Ruby, this book will help you keep your code maintainable while working on a Rails app. You’ll get to grips with the framework’s capabilities and principles to harness the full potential of Rails, and tackle many common design problems by discovering useful patterns and abstraction layers. By implementing abstraction and dividing the application into manageable modules, you’ll be able to concentrate on specific parts of the app development without getting overwhelmed by the entire codebase. This also encourages code reuse, simplifying the process of adding new features and enhancing the application's capabilities. Additionally, you’ll explore further steps in scaling Rails codebase, such as service extractions. By the end of this book, you’ll become a code design specialist with a deep understanding of the Rails framework principles.

This book is mostly geared towards intermediate to senior-level Rails engineers, but more junior-level folks can still benefit from the information contained therein.The first several chapters are an overview of how Rails works which are essential for any engineer who wants to get the most out of Rails. The rest of the book are a collection of different design patterns that someone could employ to make an existing application easy to reason about.I wouldn't recommend starting with these advanced design patterns or else you run the risk of over-engineering and introducing too much complexity unnecessarily, but if you've got an existing app that's starting to look a little crufty, these patterns can help you to abstract away the cruft in more convention-y way.The content of the book is great. It's easy to read and follow. A bit dry at times (but what technical resource isn't dry?).

I loved this book, and found it very timely given the many questions and opinions I've seen in the community over the past couple years, about how to grow Rails applications beyond what the framework gives you out-of-the-box.As an overarching concept, Vladimir lays out a compelling vision for an "Extended Rails Way" that first guides us on how to use the baked-in abstractions well, and then helps us imagine how we could extract new abstraction layers that really feel like they could be Rails.The book helped me see how I could turn design patterns into new, cohesive abstractions that rhyme with Rails, creating more harmonious codebases with reduced cognitive burden.Vladimir provides clear perspective and helpful recommendations around some of Rails' most contentious features, including callbacks and concerns.Throughout the book, there's a repeated pattern of showing less-than-ideal examples, and then reasoning our way into one or more improved solutions. I found observing his thinking here to be really informative and helpful.I was impressed by how comprehensive the book is, covering all the topics you'd expect, like Active Record and Active Storage, plus those you might not expect, like filter objects, notifications, view components, and even configuration and logging.Long story short, this is now one of two Rails books I'll be recommending that all Rails devs read.

I've been a huge fan of Vladimir's content from his conference talks and from his work at Evil Martians. "Layered Design for Ruby on Rails Applications" is a game-changer for Rails developers. With clear explanations and practical examples, it takes you from the basics of layered architecture to advanced implementation. The hands-on approach, code snippets, and best practices make it incredibly valuable. Not just theory, it tackles real-world challenges and provides insights into refactoring. This book not only teaches layered design but also transforms how you approach clean and maintainable code. For anyone serious about enhancing their Ruby on Rails skills, this book is an indispensable resource.
