Scala Reactive Programming

By: Rambabu Posa

Overview of this book

Reactive programming is a scalable, fast way to build applications, and one that helps us write code that is concise, clear, and readable. It can be used for many purposes such as GUIs, robotics, music, and others, and is central to many concurrent systems. This book will be your guide to getting started with Reactive programming in Scala. You will begin with the fundamental concepts of Reactive programming and gradually move on to working with asynchronous data streams. You will then start building an application using Akka Actors and extend it using the Play framework. You will also learn about reactive stream specifications, event sourcing techniques, and different methods to integrate Akka Streams into the Play Framework. This book will also take you one step forward by showing you the advantages of the Lagom framework while working with reactive microservices. You will also learn to scale applications using multi-node clusters and test, secure, and deploy your microservices to the cloud. By the end of the book, you will have gained the knowledge to build robust and distributed systems with Scala and Akka.

Play Framework View Template constructs

Play Framework uses the Twirl Template engine for its View Components. We will discuss some of the important, useful, and frequently used Twirl Template engine constructs so that we don't get confused while developing Play Framework examples in the upcoming sections.

Twirl View Templates

Play Framework supports different View Templates using the Twirl Template engine. We can even create our own View Template types.

Some of the important Play View Template types are as follows:

  • Scala Template: main.scala.html

Here we use main as the template name and scala to identify this as a Scala-based HTML template type.

  • Text Template: main.scala.txt

Here we use main as the template name...
