Lagom Hello Reactive System

In this section, we will develop and explore our first Lagom Framework microservice, that is, the Hello Reactive System. Even though it is a simple example, we will explore most of the required concepts in detail so that it is easy to develop our actual WF Reactive System in the coming section.

Getting Hello Service code

Fortunately, we don't need to create Lagom services from scratch. Like Play Framework, Lagom Framework also has some built-in examples. We can use them as the base to develop our services.

Perform the following steps to get the base project:

1. Access Tech Hub Project Starter using the following URL:

https://developer.lightbend.com/start/?group=lagom&project=lagom-scala-sbt

It looks like this:

2. Click on the CREATE A PROJECT FOR ME! button; it will download the lagom-scala-sbt.zip file into your filesystem.
3. Alternatively, we can clone Giter8 repositories using the following SBT command:

sbt -Dsbt.version=0.13.16 new https://github.com/lagom/lagom-scala...
