Introduction

Play is a developer-friendly and modern web application framework for both Java and Scala. This first chapter will take you through the steps in installing Play Framework for local development. This chapter will describe the Play application project directory structure, its various members and its function in a Play application.

This chapter will also introduce you to the Activator command, which replaces the old Play command. Activator is used for various stages during development, including compilation, downloading library dependencies, testing, and building. It is really quite similar to other build tools such as Ant or Maven.

This first chapter will also go about implementing Model-View-Controller (MVC) components available in Play Framework. This will be followed by source code to create controllers and routing actions using View templates and model components used to interface with an RDBMS (such as MySQL). This chapter will tackle basic HTTP forms, recognizing the importance of modern web applications being able to deal with user interactivity and data and how Play Framework provides various APIs to make life easier for developers.

By the end of the chapter, you should have a good grasp of how to implement basic web application functionalities such as form submissions and data access with MySQL, create URL routes to web actions, and create views composed of smaller, modular, and reusable view components.

Most of the recipes in this chapter assume that you have a level of familiarity with Java development, web application development, command-line interfaces, Structured Query Language (SQL), development build tools, third-party library usage, dependency management, and unit testing.
