This is a robust and easy to follow along guide for learning the Vue.js framework. I was thrown into using Vue.js in a project, but I love it a little more every day. It's well supported, has a minimal bug record on Git, and allows developers to work on HTML, CSS, and JS all on one page, which speeds up development. The only gripe I have about Vue.js in Action is that I would have liked to see a way more advanced project with all the chapters contributing towards it. Half-way through the book, the author leaves the project on the wayside and comes back to it in the last 2-3 chapters. Overall though, it's a solid book that will take you some time to finish if you are new to Vue and following along. The best attribute of the book = connecting your data to Firebase. This was a win for me.
