I recently took a course on Scala Basics. To further my knowledge, I decided to deploy a simple API on OpenShift using the Pipelines feature and build it using the Scala build tool(not Maven, as there are plenty of tasks for that).
Phase 1
First, we need an app, so as a part of the course, I developed a simple expense tracking API that has all the CRUD features and an endpoint to sum all your expenses. I'm going to walk you through the app. In order to build an API, we're going to leverage the use of the Play Framework.
