In this chapter, we introduced the Play Framework and covered typical examples where requests are routed to controllers and rendered through views following the well-known MVC pattern. We saw that the usage of the Scala syntax inside the definition of routes and templates gives us the extra benefit of compile-time safety. Such help provided to the programmer largely increases productivity and avoids spelling mistakes while refactoring, making the whole experience more enjoyable.

We also added some basic HTTP authentication to a helloworld application sample. In the next chapter, we are going to tackle the issue of Persistence/ORM, a part that is essential in any web application, involving the usage of a database in the backend to store and retrieve data. We will see how to integrate the existing persistence standards used in Java, such as JPA, and will introduce a novel but powerful approach to Persistence through the Slick framework.
