About the Book
For the longest time, Ruby and Rails developers had gems and engines as their main tools for creating structure to manage large-scale structures within their applications. This book is about a new tool in their toolbelt: packages.
Based on the work on packwerk by Shopify packages allow a much more fluid move to modularization then components ever did. The effects are astounding: discussions about where to draw boundaries can be far less technical and focus more on the business because the underlying technology gets out of the way.
The concept underlying this is gradual modularization, which the author expects we will see spread into other languages and frameworks over the coming years. Why? Because gradual modularization allows for a not-before seen level of approachability and flexibility to modularization work. Work that required difficult decisions that were hard to reverse changes. Those decisions are now the extreme points on a spectrum of options where the right thing for the team can be somewhere in between.
About the Author
Stephan leads the product infrastructure engineering team at Gusto. Gusto has quite a bit of Ruby on Rails in the software behind their offerings and provides the perfect ground for the analysis of complex applications due to "Payroll" being both a deep and very wide domain. And Gusto is a lot more than payroll.
Stephan is the author of Component-based Rails Applications in which he lays out the previous iteration of Ruby and Rails modularization based on gems and engines. He is currently working on a new book called Gradual Modularization for Ruby and Rails, which improves on his previous ideas by reducing the cost of the needed work and increasing the opportunities for benefiting from it.
