I am in the middle of setting the foundations of a new product project going DDD, CQRS and Event Sourcing so imagine my surprise when I see a book about... that.

Then I see JavaScript and Node.js.

So this isn't a book on either of DDD, CQRS or EventSourcing. It's about JS.

This comment breaks both the HN guidelines and the Show HN guidelines. Please don't do that. We're trying to have a culture in which people who share their work get substantive feedback and discussion. Cheap dismissals undermine that badly—and since they're the internet default, we need to be conscious about this.

In fact, the book was called "Implementing DDD, CQRS and Event Sourcing in Node.js" up until the release of its complete version. I thought about this for a longer time and decided to remove the "in Node.js" part from the title. Instead, I made it clear in the book description. In my opinion, the book can be valuable for anyone who is interested in the concepts, regardless of technology choices.

I think that it is fair to say that my book is partially also about Node.js, but not primarily. I wouldn't say though it is about JS. In fact, many of the code examples would look similar in other languages. Furthermore, the use of Node.js helps to provide concise code examples and executable code without much ceremony.

When reading "Implementing Domain-Driven Design" by Vaughn Vernon, all the code examples are in Java. The book "Enterprise Integration Patterns" has a lot of code examples and all of them are also in Java. The most recent edition of "Refactoring" by Martin Fowler uses JavaScript. Still, I wouldn't say that these books are about a particular programming language.

What's wrong with this? The underlying architectural patterns and abstractions you should be able to pick out and apply to your technology of choice.

I don't know where that came from but please don't make things up that look like quotes when they're not, and especially please don't use that as a snark trope.

(If someone said that and you're actually quoting them and they edited it out, that's of course different.)
