Single page apps in depth
This free book is the book I would have wanted when I started working with single page apps. It's not an API reference on a particular framework, rather, the focus is on discussing patterns, implementation choices and decent practices.
I'm taking a "code and concepts" approach to the topic - the best way to learn how to use something is to understand how it is implemented. My ambition here is to decompose the problem of writing a web app, take a fresh look at it and hopefully make better decisions the next time you make one.
