Play Framework Cookbook
Author : Alexander Reelsen
Play framework is an upcoming framework that comes in the growing breed of rapid application development, using convention over configuration based web application development.
The thing that sets apart this framework apart from others is the customizability of the framework in the jvm, while taking advantage of either java or scala as desired. However, owing to the late arrival of play, there has been a lack of tutorials and documentation in order to solve real world problems with this framework.
This book, being a cookbook covers the topics, head-on and gives practical insight into building web application while covering loads of practical topics, from installation to deployment.
The book has been divided into 7 chapters and a small appendix. The first chapter covers the basics and is good for those coming without rails experience. However, the chapter also presents recepies for customizing all parts of the framework- pretty much everything that other technology cookbooks pack into themselves from cover to cover. The middle chapters dig deeper into the framework and integration with external services. One thing that is special in this cookbook is it devotes 3 chapters to modules as extensibility via modules is one of the main differentiating factor that play framework offers. In line with practicality, the book devotes its last chapter totally on deployment and release functions. This does omits the cloud vendors that provide paas for play framework directly, but as a lot of cloud offerings for play are unfinalized, they do not find any mention. The appendix is a disappointment as there are no pointers for carrying out further. As with any upcoming technology, it is imperative to look out for more resources in order to update and correct ourselves with its ecosystem. This is especially important as play 2.0 would be out on beta by the end of this year and a reader always expects pragmatism from a hands-on cookbook. Also, due to the flexibility of this framework, various PAAS vendors are providing, or planning to provide play support, which deserves at least a listing of these services. The author clearly states his intention behind leaving scala based applications in play, and this hopefully might make its way in future editions.
Overall, this is a book that lives well up to its expectations on providing us with something apart from the documented portions and the stock examples supplied with the play distribution while providing insights into the activities covered and making them flexible enough to be used practically.
For anyone learning play framework and looking to go beyond the examples for making interesting and practical applications, I’d heartily recommend this book.
