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.

Useful ConductR commands

So far, we have discussed a couple of important and frequently used ConductR Sandbox commands. In this section, we will discuss some more useful ConductR Sandbox commands:

  • To get some help about sandbox command, please use the following command:
ram$ sandbox -h
usage: sandbox [-h] {version,run,start,restart,stop,ps,logs} ...

The following -h or --help are optional arguments:

-h, --help show this help message and exit
  • The following are Sandbox's useful commands:

To use one of the following sub-commands:

version     Print version
run (start) Run ConductR sandbox cluster
restart Restart ConductR sandbox cluster
stop Stop ConductR sandbox cluster
ps List the pids for ConductR core and agent sandbox processes
logs Fetches the logs of ConductR core and agent processes
