Single Page App Backends: Where Laravel Beats Node.js

I’ve been commissioned to write a book about building full stack Vue.js apps. Since many Laravel developers are interested in Vue (Vue now ships with Laravel), the publisher wants the book to focus on full stack Vue.js with Laravel.
In preparing for the book, I knew I would have to answer a very important question for myself: why would anyone even want to use Laravel as a backend for a single page app when they can use Node.js?
