Original author here. Yes this book was written a long time ago when I was into the node ecosystem. A lot of the book was copied into the official docs later https://github.com/libuv/libuv/pull/1246 https://github.com/libuv/libuv/pull/1246. The book definitely does not capture new things. I do not intend to update it, but I still look at pull requests.
