Learning Play! Framework 2

By: Andy Petrella

Overview of this book

<p>The Learning Play! Framework 2 has been created for web developers that are building web applications. The core idea is to focus on the HTTP features and to enable them through a simplification lens. Building a web application no longer requires a configuration phase, an environment setup, or a long development lifecycle - it's integrated!<br /><br />Learning Play! Framework 2 will enable any web developers to create amazing web applications taking advantage of the coolest features. It's the fastest way to dive into Play!, focusing on the capabilities by using them in a sample application. Although essentially Java based code, a Scala version is presented as well – giving an opportunity to see some Scala in action.<br /><br />After setting up the machine and learning some Scala, you will construct an application which builds from static to dynamic, before introducing a database. <br /><br />Then we'll focus on how data can be consumed and rendered in several ways. This will enable some real time communication through WebSocket and Server-Sent Event – on both server and client sides.</p> <p>The book will end with testing and deployment, which completes any web development project.</p>

Summary


We're at the halfway point of the book and we've already built a forum-like web application with really basic features, but we are able to at least create chatrooms for particular topics, join them, participate with messages, or add images to them. All this without any pain or boilerplate, thanks to the content management features that Play! Framework 2 puts in our hands for free.

Indeed, in this chapter we were able to deal with complex routing involving several ways to provide information, using different HTTP methods and URLs with or without extra parameters. Such requests were used to feed the server with data very easily, by using a single API that is independent of how the data is represented. For instance, on both sides we were dealing with forms.

Body parsing was there to help us, and to facilitate resource binding with our constrained forms. Moreover, they are consuming data in such a way that even large data sets won't crash the server—they are consumed reactively.
