Hi all,
The book aims at being a guide for writing performant applications with Play, navigating around some of the pitfalls that come with the evented server model. It also gives an introduction to some of the fundamental aspects of functional programming that turn out to be quite useful when writing asynchronous programs, and introduces some useful tools available for this purpose in Scala (Futures, Actors, Reactive Streams). Lastly, it also addresses a few useful topics such as where and how to keep state, how to deploy and operate a Play application, and how to test it (performance-wise).
More background on the book can be found on
my blog.
Last but not least, there is a 50% discount with the code mlbernhardt.
Cheers!
