About the Book
(This book is currently in a "beta" state, with some medium-sized changes coming to its code in the near future. Hence the "95% complete" part. I'd still love for people to read it in the meantime though!)
The default structure of Rails applications hasn't changed all that much in over a decade. And with good reason: this directory structure makes it easy to jump into building a Rails application.
While I agree that this way is still extremely simple and great for getting started within a Rails application, I do not agree that this is the best way to organise a Rails application in 2018 with long-term maintenance in mind. A decade of Ruby development has produced some great alternatives to Rails' MVC directory structure that are definitely worthwhile to consider.
The `rom-rb` gems allow us to interact with a database with just as much ease as Active Record, but with the added benefit that persistence and business logic aren't bundled together in the same class.
The `dry-rb` gems allow for splitting the validation logic away from the business logic's class (dry-validation) and also provides a sensible alternative to the community-wide pattern of service objects (dry-transaction).
This guide covers how you would go about integrating these gems into a brand new Rails application, building features in an iterative fashion.
