Summary


In this chapter, we have experimented with the iteratees pattern supported by the Play Framework to handle streams reactively. We have then used it along with WebSockets and Akka to write a small, reactive web application.

The samples of reactive web applications that we have addressed and discussed in this chapter are just a glimpse of the endless possibilities of making applications that react to events and are resilient to failure and load. As web applications grow in complexity, such architectures should gain in popularity and adoption rate.

Being able to asynchronously process streams in real time is, in our opinion, a big competitive advantage if this functionality is built in a manageable and maintainable way. This is precisely the goal that the Play Framework combined with Akka illustrates.

In the next and the last chapter of this book, we are going to consider a few areas where we think Scala provides additional, convenient help.
