Play is a framework to write web applications using Scala or Java. It provides a productive development environment, allowing you to just hit the "refresh" button in your browser to compile your changes and reload the application. Because of its stateless nature, the framework makes it easy to build applications that scale. Play provides a reactive programming model to harness the event-driven HTTP layer.
This book provides a step-by-step walkthrough of how to build a complete web application following best application development practices using Play framework 2. All aspects specific to web-oriented architectures are covered: the HTTP layer, JSON manipulation, HTML templating, asset compression and concatenation, form submission, content negotiation, security, and HTTP streaming. The book will also provide detailed architectural insights into Play framework to give you a better understanding in order to successfully build scalable applications.
