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.

Reactive Microservices with Lagom

In this chapter, we will discuss Lightbend's Reactive Platform. It has a Reactive Microservice Framework, that is, the Lagom Framework. We will be developing our WF (Weather Forecasting) Reactive System, using this framework.

Nowadays, like Reactive, microservices or microservice architectures are becoming more popular. Everyone is moving to the microservices architecture. All greenfield projects are starting with this architecture, and old monolithic applications are also converting to microservices step by step to get their benefits.
