“A practical handbook that will provide tremendous help while designing the codebase of your mobile app” —Jovche Mitrejchevski, Software Craftsman "A great book if you're starting to understand architectures. It starts from the very scratch and keeps evolving till you get the main concepts of clean architecture I was impressed at how many similar opinions we have about this." --Antonio Leiva, Android Google Developer Expert"This book really surprised me. I found the architectural design advice useful for any software developer. Petros's writing style is very easy to read, and I was able to get through the whole book in a couple of days. If you are a mobile developer, you will get even more from this book. If you are not, you still should read it." -- Sandro Mancuso Software Craftsman / Managing Director at Codurance“Provides a carefully balanced view on designing, and growing, an app's architecture in line with the size and requirements of the codebase. A very helpful tool to make more practical sense of how an app's architecture can (and should) evolve over time.” —Donny Wals, iOS consultant & author—————————————————————————————————————————The long-awaited book tailored to the architectural needs of Mobile Applications. Clean Architecture is by now a standard in Mobile development. It is listed in every job ad and is assessed in every technical interview. Particularly for senior, architect, and lead positions.Most software books are written with Backend systems in mind. While the software basics are common, the details differ. And details are crucial. Translating their wisdom into Mobile codebases requires effort and often includes several unsuccessful attempts. This is the one book you need to properly architect Mobile apps. It is platform-agnostic and includes coding samples of both Android & iOS. Read it, and you’ll learn how to:Architect your mobile application by Clean Architecture.Apply the S.O.L.I.D principles.Leverage Reactive Programming & MVI.Draw proper architectural boundaries.Define adequate testing strategies.Leverage Evolutionary design and increase agility.Identify when Clean Architecture is needed and when simpler approaches work better.“Best practices” don’t exist. Some practices solve specific problems while introducing problems that didn’t exist before. What works for a startup doesn’t work for an enterprise app, and vice versa. This book goes the extra mile to clarify when each practice is helpful. And most importantly, when to avoid it.The book doesn’t only stick to theory. It includes several repos with sample apps that put everything into practice. Theory backed up by practice is called experience. That’s what makes an architect.
