We need more books of this nature. The free chapter didn't really sell me on the book, but for $26 even if there's only one insight I pick up it may be useful. So I picked up a copy, but I do have some concerns.
I've been pretty cautious about technology decisions. When some new tech gets hyped up, it automatically gets flagged in my brain almost like spam or some infomercial product. Everything has tradeoffs and if the whole industry is telling me I must do X without stating any of the downsides of X those red flags go up. I'll use my own judgement to see if X makes sense. And for the last decade or more I feel I've been on the right side of history. I read the free chapter and the immediate concern is the next chapter which dives into CQRS. CQRS is one of those technologies that was massively hyped up and I'm sure caused lots of projects to fail. Search HN on CQRS and it typically falls into "architecture mistakes" more often than not. So I'm hoping the book is very careful in its recommendations or at least dives into some tradeoffs.
One side note: I slightly disagree a bit with the free chapter's "four steps of evolution". The app I'm building has a very complex domain such that we don't have many competitors and the barrier to entry is high. You can't simply build an MVP that does some small subset and hope to add as you grow as the product would not be functional. You need to handle the domain complexity up front just to deliver an MVP that does some bare minimum. So perhaps this app or industry may be an edge case, but perhaps some caveat is needed in that chapter.
Thanks for this comment. It is important to consider everything you said. CQRS is part of this book, but it is more of an explanation and might help you at some point (but does not need to). I think that's the main problem of CQRS - it is not understood well.
Throughout the book, I describe many concepts. Sometimes, I give some recommendations, and sometimes, no.
I accept your note—these four steps of evolution help you find yourself in one of them. Simplicity can be solved in multiple different ways; it is just the direction of keeping the solution as simple as possible (sometimes it will be more complicated, and sometimes less).
Enjoy reading it; if you don't like it, you can always return it within 60 days (Leanpub policy).
