In this second and last part, we’ll see how to use Akka HTTP to create RESTful Web Services. The idea is to expose the operations defined in the first part of this article, using HTTP and JSON.

Akka HTTP implements a full server/client-side HTTP based on top of Akka Actors. It describes itself as “a more general toolkit for providing and consuming HTTP-based services instead of a web-framework“. One interesting aspect is that it provides different abstraction levels for doing the same thing in most of the scenarios, i.e., provides high and low level APIs. Akka HTTP is pretty much the continuation of the Spray Project and Spray’s creators are part of Akka HTTP team. In our example, we’ll be using the high level Routing DSL to expose services, which allows routes to be defined and composed by directives. We’ll also use the Spray Json project to provide the infrastructure needed to use JSON with Akka HTTP.

This article is split in 2 parts and it aims to show how to create a small application (or a microservice if you prefer) using Akka HTTP (Scala) and Redis database.The application is very focused and provides means for a customer to be added, removed and retrieved.

In terms of technologies/tools/libs, the following ones will be used:

• Scala
• SBT
• Akka HTTP/Akka HTTP Json Support/Akka HTTP Test kit
• Rediscala
• Scalatest
• Redis database

In this first part, we’ll focus on the layer responsible for communicating with Redis, while the second part will focus on Akka HTTP.
